Product introduction of VK12-24P solid-sealed pole type indoor medium voltage vacuum circuit breaker

VK12-24P solid-sealed pole type indoor medium voltage vacuum circuit breaker is a solid-sealed pole-type circuit breaker specially designed by our company to invite domestic and foreign experts to specialize in design, with unique technology and obtain a proprietary model certificate. The main design concept: the main circuit uses solid-sealed poles to improve the environmental adaptability and insulation reliability of the circuit breaker; improve the mechanism design, extend the mechanical life and improve the mechanical reliability. Reliable mechanical and electrical performance, extended mechanical and electrical life make maintenance-free circuit breakers possible.
The VK12-24P circuit breaker is an indoor switchgear component with rated voltage of 24KV and AC 50Hz. The product complies with the relevant domestic and international standards such as GB, DL and IEC, and its performance reaches the level of M2-E2-C2.
The VK12-24P circuit breaker is equipped with a special propulsion mechanism to form a handcart unit. The circuit breaker is equipped with a reliable interlocking unit to meet the user's “five-proof” protection.
Product information of VK12-24P solid-sealed pole type indoor medium voltage vacuum circuit breaker  
1. The main circuit adopts a solid-sealed pole.
The main circuit of the circuit breaker adopts APG process forming technology. The high-performance epoxy resin is used to seal the vacuum interrupter and the upper and lower outlets together, so that the vacuum interrupter is protected from dust, moisture and pollution, and the environmental adaptability is improved. And insulation reliability.
2. There is an umbrella group between the upper and lower outlets of the solid-sealed pole.
An umbrella group is designed between the upper and lower outlets of the solid-sealed pole, which increases the creepage distance of the outer insulation between the fractures and improves the insulation reliability of the circuit breaker.
3, the circuit breaker is M2 pole circuit breaker  
Superior mechanical performance, can be used in frequent operation, the circuit breaker meets the requirements of M2 circuit breaker, and the mechanical life is up to 20,000 times.
4, the circuit breaker is E2 circuit breaker  
The circuit breaker passed all type inspections at the Shanghai High Voltage Electrical Appliance Testing Center, meeting the requirements of the E2 circuit breaker. The small current circuit breaker broke the full capacity short circuit current for 30 times, and the large current circuit breaker broke the full capacity short circuit current for 20 times. .
5, the circuit breaker is a C2 circuit breaker  
During the breaking current of the circuit breaker, it has a very low probability of heavy breakdown and meets the requirements of the C2 class circuit breaker.
6, the circuit breaker mechanism has excellent anti-corrosion function  
The mechanism parts adopt advanced surface treatment technology to make the parts more resistant to corrosion and higher mechanical stability.
7, using buffers with excellent cushioning performance  
The specially designed buffer reduces the overshoot and tripping of the circuit breaker and improves the mechanical life of the circuit breaker.
8. Insulation rods made of BMC material  
The insulating material of the insulating rod is BMC, which not only meets the requirements of mechanical strength but also has a large creepage distance along the surface, which improves the insulation performance of the circuit breaker.
9, the circuit breaker can be used at a temperature of -25 ° C  
The circuit breaker uses special low temperature grease and a buffer that can operate at low temperatures, making the circuit breaker fully usable at -25 °C.
