10kv high-voltage vacuum circuit breaker manufacturers choose ZW32-12M outdoor high-voltage permanent magnet vacuum circuit breaker using advanced high-reliability permanent magnet operating mechanism, equipped with intelligent controller. As the outdoor distribution equipment with rated voltage of 12kV and three-phase AC 50Hz, it is mainly used for breaking and closing the load current, overload current and short circuit current in the power grid. It is widely used in substations, industrial and mining enterprises, and rural power grid distribution systems for protection and control and frequent operation places. This product is matched with the SDMDR intelligent controller, which can meet the requirements of the distribution automation system. 1. The oil circuit breaker uses insulating oil as the arc extinguishing medium, which is called the oil circuit breaker. It can be divided into more oil circuit breakers and less oil circuit breakers.
The insulating oil in the multi-oil circuit breaker is used not only as the arc extinguishing medium, but also as the main insulation between the contacts after the contacts are disconnected and the main insulation between the live part and the grounded shell. Many, metal consumables are large, prone to fire or explosion, large volume, low processing requirements, durability, low price and so on. At present, in the power system, except for the outdoor multi-oil circuit breakers of individual models such as 35 kV, the production and use of other multi-oil circuit breakers have been discontinued.
The insulating oil in the oil-less circuit breaker is mainly used as an arc extinguishing medium, and the insulation between the live part and the ground is mainly made of porcelain bottles or other organic insulating materials. This type of circuit breaker is called a low oil circuit breaker because it uses less oil. The oil-less circuit breaker has the advantages of less consumables and low price, but it needs regular maintenance, which may cause fire and explosion. Although oil-less circuit breakers are currently used, they have been gradually replaced by new circuit breakers such as vacuum circuit breakers and sulfur hexafluoride circuit breakers.
2. Vacuum circuit breaker Vacuum circuit breaker is a circuit breaker that uses "vacuum" as the insulating medium and arc extinguishing medium. The so-called "vacuum" here can be understood as a gas space with a gas pressure far below an atmospheric pressure, and gas molecules in the space are extremely rare. Vacuum circuit breaker is a circuit breaker made by installing its dynamic and static contacts in a "vacuum" sealed container (also called vacuum interrupter).
3. Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride gas with high-quality insulation and arc extinguishing performance as the arc extinguishing medium. Sulfur hexafluoride circuit breaker has the advantages of strong arc extinguishing performance, no spontaneous combustion, small size and so on.

Daily news:
The story of Pu Songling Cao Ting's road question is widely circulated because of concentration. Qing Dynasty writer Pu Songling built a thatched pavilion on the side of the road to record the folk stories and bridges told by pedestrians. After decades of hard work and collecting, and his own creation of sleeping and forgetting food, he finally completed the ancient Chinese literature. An epoch-making glorious masterpiece "Liao Zhai Zhi Yi" in history. This spirit of concentration can't help but make us feel emotional. Success may just be an accessory of concentration. When you really focus, you will find that in fact, you get more than success.
Switch structure characteristics:
1. The circuit breaker adopts three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no risk of combustion and explosion, maintenance-free, small size, light weight and long service life.
2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve the moisture resistance and anti-condensation performance, and is especially suitable for use in severe cold or humid areas.
3. Three-phase pillars and current transformers are imported outdoor epoxy resin solid insulation, or adopt epoxy resin outsourcing organic silicone rubber solid insulation; have the characteristics of high and low temperature resistance, ultraviolet resistance, aging resistance and so on.
4. The operating mechanism adopts a miniaturized spring operating mechanism, the energy storage motor has low power, and the opening and closing energy consumption is low; the mechanism transmission adopts the real transmission mode, the number of parts is small, and the reliability is high. The operating mechanism is placed in a sealed mechanism box, which solves the problem of corrosion of the operating mechanism and improves the reliability of the mechanism.
5. The opening and closing operation of the circuit breaker can be manual or electric operation and remote control operation. It can be matched with an intelligent controller to realize power distribution automation, and can also be combined with a reclosing controller to form an automatic recloser and a segmenter.
6. The circuit breaker can be equipped with two-phase or three-phase current transformers for over-current or short-circuit protection, and can also provide current collection signals to the intelligent controller; according to user requirements, it can be installed with current transformers for measurement.
7. The circuit breaker can be equipped with a three-phase isolation switch. When the isolation switch is in the open state, there is a visible break, and it has an anti-misoperation interlock device with the circuit breaker body. Only when the isolation knife is fully closed or completely The circuit breaker can only be operated when it is open. Insulators for lightning arresters can be connected together for easy maintenance.
