What is the intelligent test platform for the generator (product library purchase supply) group?
Based on the traditional load test equipment, Kaixiang Technology has developed a new intelligent test platform for generator sets based on years of research and summary of customer needs.
   The genset intelligent test platform is a system integration project that can efficiently connect the customer's genset to be tested, load test equipment, electric drive system and data acquisition system, and control through intelligent and automatic software (purchasing and supply of product warehouse). To achieve rapid testing of multi-station, multi-voltage level generator sets, greatly saving labor costs, improving test efficiency, and reducing the cost and difficulty of maintenance and upgrade.
   Kaixiang solution
   Kaixiang generator set intelligent test platform is designed to solve the above-mentioned common problems of testing, and provide users with a new test system that can adapt to a variety of test requirements, can complete tests quickly and efficiently, and has the potential to upgrade and expand.
   The following is a combination of Kaixiang Technology's intelligent test platform project for a generator set built by a generator set manufacturer to explain the design concept and characteristics of the platform.
   The maximum test power of the platform is 27800kVA, and the voltage can cover the main voltage level of three-phase 400V to 11kV, the power factor is adjustable by 0.8, and the frequency is 50/60Hz.
   The platform consists of the main parts such as console, switch cabinet, connecting cable, communication cabinet, integrated protection cabinet, transformer (purchasing supply), and load cabinet.
   System control room
  Â
   The center of the intelligent test platform of the generator set is the system control room, which can display the load loading state, control the loading and unloading of the load, the parallel of the generator set, select the voltage, and select the working mode. It can be controlled by the switch of the console, and it can be controlled by the test software.
   System control software
   Pre-installed control software in the console can display test data in real time, and can realize one-click addition and subtraction through the preset process, and automatically complete the specified test content.
   Test data can be automatically stored and test reports in a standard format can be generated to assess the health of the generator set.
   Intelligent software control can greatly improve the efficiency of operators, eliminating the need for cumbersome manual operations and reducing work costs.
   Switchgear
   The switchgear is the coordination center of the system, and the control software indirectly controls other components through the switchgear.
   The test platform usually has more than 2 working stations, and the test voltage, frequency and power of each station may be different. In order to ensure the safety and reliability of the connection between the generator set and the load cabinet, it is necessary to ensure the scientific operation of the parallel operation through the orderly opening and closing of the switch cabinet.
   Tubular bus
   The tubular busbar is used to connect the primary circuit in the system. Compared with the copper busbar used in the traditional test system, the tubular busbar has a larger current carrying capacity, higher thermal resistance coefficient of the insulating material, no environmental interference, high reliability, and installation. Convenient and less maintenance work, more suitable for high-power test environment. Thereby the maximum test capacity and reliability of the system is further improved.
   Contact cabinet and control cabinet
   The communication cabinet and the control cabinet can combine the resources of each work station to realize the parallel or interlocking of the load and the generator set, thereby realizing the rapid switching between various test voltages and powers, so that the operator can test the units of different specifications. There is no need to repeatedly wire the unit and the load, and the switching can be done quickly by software.
   At the same time, the redundancy of the system is also increased because the resources of each station can be shared and combined. Even if the test equipment of a certain station needs to be repaired and rebuilt, it will not affect the normal work of other stations, and greatly improve the continuous working capacity of the system.
   Comprehensive protection cabinet
   In order to ensure the electrical safety of the liaison cabinet during parallel operation, the system realizes the differential protection of the generator set and the high and low backup protection of the transformer through the integrated protection cabinet. Therefore, the system avoids a short circuit accident when the test voltage is switched and the units of each working station are combined.
The integrated protection cabinet is the lowest level of protection for one-click operation of the software, which greatly improves the system fault tolerance and further reduces the requirements for operators.
   transformer
   Through the transformer, the test voltage can be switched from low voltage 400V, 690V to medium voltage 3.3kV, 6.6kV, 11kV, and the need for the load cabinet's own voltage level is reduced. Thereby reducing the cost investment of the load cabinet in the system and increasing the system adaptability.
   Load cabinet
   The load cabinet converts the power output of the generator set during the test and safely consumes it. Load cabinets are usually installed outdoors and are weather and corrosion resistant. The load cabinet of this system adopts special insulation design to ensure insulation safety even if it is working in rainwater environment for a long time. The load cabinet also has a self-protection function, which can automatically stop and protect in time when the system voltage, current and temperature are abnormal.

There are many kinds of products which need filtration in industrial production. The material properties of these products are very different, and the purpose of separation is different. Therefore, it is necessary to select the filter equipment scientifically and reasonably according to the production needs such as material characteristics and separation purposes, in order to play its role effectively.
At present, the requirement of filtration equipment in industry is that the filtration accuracy is high, so that the solid content in the filtrate is low, and even the filtration precision is based on the number of solid particles in the filtrate.
In order to ensure the stability and reliability of the system, the cleanliness of the oil with precision components such as servo parts is strictly controlled in the international hydraulic system, and the new oil cleanliness is required to reach the fifth grade of the American Aerospace Standard nas1638 (American Aerospace Standard), so as to ensure the stability and reliability of the system. But in reality, the cleanliness of new oil is only 10-11 of nas1638. If the new oil is used without strict filter and purification, it will bring serious harm to the life of the precision components and the reliability of the work of the whole system. The cleanliness of hydraulic oil can be improved fundamentally only when circulating filtration is carried out simultaneously with the operation of hydraulic system.
Reverse osmosis filtration equipment is widely used in industrial production, industrial pure water system is designed from reverse osmosis process, referred to as reverse osmosis equipment. The water quality of reverse osmosis equipment is required before influent. If the water flow through reverse osmosis membrane directly through high pressure for a long time, it will cause membrane blockage.
In general, there are multi-medium filters, ion exchange, various kinds of Precision Filters in the pre-treatment equipment of the whole pure water system. These pre-treatment filters can effectively remove the suspended matter in the water.
According to the needs of the users, different levels of processes are used to make the quality of the produced water up to the standard. Of course, its price is also determined by the configuration of reverse
osmosis equipment.
