VN1-40.5E medium-voltage AC vacuum circuit breaker is a new product designed by our company. The main circuit is with the solid insulated structure and uses the advanced epoxy resin sealed technology. Firstly it assembles a integrated sealed pole column with the vacuum interrupter, the main circuit, the insulated support and so on, which enhances the environment endurance of the vacuum circuit breaker. 1. The main circuit section and operating mechanism section is upper and lower arrangement, which optimize the electric field distribution, increase the insulated reliability, also reduce the circuit breaker depth direction size and reduce the matched switchgear depth greatly. 2. The live part of main circuit is cast in the epoxy resin cylinder, which make the interrupter be exempt from the environmental effect and the external mechanical force injury, also cause the circuit breaker no arc-over between phases and on the interrupter's surface and enhance the insulation of circuit breaker. 3.Current carries are fixed reliably in the position by the epoxy resin, do not need the extra fastener, reduce the number of accessories used for assembling circuit breaker pole columns, reduce the installation error and enhance the reliability of installing the circuit breaker. 4. As a result of using the sealed technology, the circuit breaker volume reduces greatly. The matched cabinet width is only 1200mm, heighten 2400mm, depth 2600mm. 5. The VN1 circuit breaker is based on the self-supporting structure of bottom plate, has overcome the primary contacts linking due to the circuit breaker submersion and also transport conveniently.

Our old Greek customer, Evander, emailed me in November last year that he sent me a sample of hydraulic cartridge relief valve, and stressing that it was not his, but one of his partners, Ptolemy, and also attached Ptolemy's contact information. After receiving the sample and communicating with Ptolemy, we learned that the hydraulic cartridge relief valve was produced by a local cartridge valve manufacturer in Greek and installed in their hydraulic cylinder, which was unstable. Their engineers said that the root cause was the high back pressure of the hydraulic system and the insensitive opening of the hydraulic cartridge valve. We can't determine the hidden dangers of the hydraulic cartridge valve just according to the original sample. I suggested Evander sending us the video of abnormal hydraulic cylinder, the drawing of hydraulic cartridge valve, and the schematic of the system. After discussing, AAK engineers advised that the problem can only be solved by reducing the opening back pressure resistance of the hydraulic cartridge valve. Perhaps because of Evander's endorsement, Ptolemy paid the development fee on the second day. I have always believed that for industrial products such as hydraulic cartridge valves, it is difficult to get the order without trust. With trust and reliable manufacturing quality, it is easy to get the order. After 40 days, AAK sent 20 samples of hydraulic cartridge valve. Yesterday, Ptolemy emailed me that AAK hydraulic cartridge relief valve was used on the hydraulic cylinder. The prototype operated stably and the hydraulic cartridge valve opened sensitively. AAK hydraulic cartridge valve is stable and sensitive under high back pressure. We optimized the structure of the original hydraulic cartridge relief valve from 3 aspects. 1. The valve sleeve of the hydraulic cartridge relief valve has an oil inlet cavity, and the outer circle of the valve sleeve is provided with a plurality of annular through holes as oil outlet, and oblique holes are set to control the oil outlet. 2. The middle part of the main valve spool is provided with a small hole connecting the oil inlet cavity and the inclined hole, and the main valve spool can slide in the valve body to form a spring cavity that is relatively closed to the oil inlet cavity, and the spring cavity is equipped with a pressure regulating spring. 3. The left end of the valve body is installed with an adjustable rod that can be rotated and retracted and has a lock nut. The pressure regulating spring on the adjusting rod is connected to the main valve spool. The outer diameter of the right end of the valve body is provided with a sealing groove to place the sealing ring group. Two sealing grooves are set on the left side of the external thread of the valve body, and the sealing ring group is placed to seal the connection with the socket to prevent oil leakage. The optimized AAK hydraulic cartridge relief valve equalizes the pressure difference

The Mexican manufacturer can't get the hydraulic pressure control valve done, and AAK succeeded in the first sample Bahamonde is from Mexico and has cooperated with AAK on several non-standard hydraulic valves. At the beginning of this year, he was stuck by a hydraulic pressure control valve. A hydraulic crank-type lift developed by their company will appear at the exhibition in July. In order to get the test run successful as early as possible, Bahamonde found a local hydraulic pressure control valve manufacturer to make samples. The equipment commissioning was not smooth, and the fluid flow and pressure at the oil outlet of the hydraulic pressure control valve are unstable, resulting in inaccurate positioning of the hydraulic crank-type lift and unstable operation control. The original manufacturer said that the sample was based on the original design. Maybe there are defects in the original design. Bahamonde had contacted several local hydraulic valve manufacturers one after another, but none of them were willing to cooperate in redesigning the hydraulic pressure control valve and making samples. As the exhibition period was about to arrive, Bahamonde was very worried. Bahamonde thought of AAK because we had the experience of modifying their original design before. According to his hydraulic schematic diagram and the design of the original hydraulic pressure control valve, our engineers have a basic idea after discussing, but it takes time. Bahamonde told me that he could give me 50 days at most. After 3 times of design adjustment and 6 times of simulation, a new design scheme was determined. After 45 days, 30 samples of hydraulic pressure control valves were sent out. 2 weeks later, Bahamonde told me that the test was successful, and asked me to wait for the good news of their exhibition. Last week, Bahamonde placed an annual order of 1,200 hydraulic pressure control valves, and also mentioned that their hydraulic crank-type lift was very popular during the exhibition. Their engineers admire our technical team's brainy thinking. AAK made it successful this way: For this hydraulic pressure control valve, we changed the structure of the balance cone valve to the balance plunger type, which can let the pressure, connect the control working port and the pilot control port, control the fluid flow and pressure at the oil inlet, and conduct pilot control at the pilot port. At the same time, the hydraulic pressure control valve acts as the main stage of pressure control. The pilot flow of the valve is very small but the flow capacity is very strong, so the circuit design is flexible. And the newly designed hydraulic pressure control valve can integrate all pressure control circuits with external control functions, such as external control opening, external control closing, multi-stage pressure setting, etc., into the circuit, improving the stability of operation control.
