Zw32-24 series outdoor high voltage vacuum breaker is used in Ac 50Hz ,rated voltage 24kV three-phase power system for closing/breaking load current, overcurrent and short-circuit current. the breaker can equip with reclosing controller to identity break current characteristics and achieve multiple automatic reclosing or fault isolation. Self-provided PT as a power source,it becomes a smart circuit breaker able to controller with signa output of voltage and current.The electronic PT provides power supply and can complete three-stage composite protection of overcurrent delay inrush current delay, and short-circuit and quick-break.
It can be equipped with a spring operating mechanism, which has basic functions such as breaking and closing load current, overload current and short circuit current. It is the basic type of Zw32-24 series. The circuit breaker and the isolating switch can be combined to form a "combined circuit breaker" (hereinafter referred to as "combined circuit breaker") with a distinct fracture. On the isolating switch, the user can choose to use the silicone rubber insulating sheath, which has the characteristics of rain, snow, sand and anti-pollution and corrosion, and can effectively avoid the freezing and oxidation of the isolating switch.
The circuit breaker can be eguipped with a lightning arrester, and the lightning arrester can be installed on any side of the incoming and outgoing lines according to user requirements;
The circuit breaker can be equipped with an inrush current controller, which has the function of escaping flow and over-current breaking: the circuit breaker can be equipped with 2 to 3 measuring or measuring transformers.
The recloser controller can be configured as a recloser type intelligent circuit breaker. The basic type and reclosing controller are suitable for the occasion of easy-to-access power supply. The PT type and coincidence controller are suitable for the occasion of no power supply. The intelligent circuit breaker is suitable for the radiation type power supply and the ring network power supply system to help the system eliminate transient faults and automatically Restore power supply, and also isolate ,faults to achieve distribution network automation
ZW32-24 outdoor AC high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is rated voltage of 24kV, 50Hz three-phase AC outdoor power distribution equipment. It is mainly used to open and close the load current, overload current and short circuit current in the power system. Overload current and short-circuit current. Suitable for substations and industrial and mining enterprises in the distribution system for protection and control purposes, more It is suitable for the rural grid and the place of frequent operation.
1. The shell is made of high-quality stainless steel or ordinary steel plate, which is sprayed with UV resistant varnish after Dacromet antirust treatment process. The product has excellent anti friction, anti salt fog and other anti environmental properties.
2. APG fixed insulated pole is encapsulated with silicone rubber (as insulation and buffer), with small volume, excellent anti condensation performance, long working life and reliable performance.
3. The operating mechanism is a spring operating mechanism, which can be manual or electric. When necessary, a remote control operating device and a device to avoid closing inrush current can be added. The required power of external power supply is no more than 70W, which is easy to be equipped with backup power supply. The buffer device with unique design has excellent performance, small rebound and low noise.
4. The arc extinguishing chamber adopts special stainless steel brazing technology without electroplating, with high welding quality, stability and reliability and low air leakage rate. Special ceramic metallization formula and advanced ceramic metallization process are used in the manufacturing process to ensure the air tightness of the product, and the tensile strength is 130Mpa Complete primary sealing.
5. The current transformer is made of high-quality magnetic conducting material and composite insulation of epoxy resin and silicone rubber. It has the advantages of large capacity, high dynamic thermal stability, high precision level, maintenance free and high reliability.
1. The circuit breaker adopts a three-phase pillar structure, which has the characteristics of breaking performance, stability and reliability, no danger 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 moisture-proof and anti-condensation performance, and is especially suitable for use in severe cold or humid areas.
3. Three-phase pillars and current transformers are insulated by imported outdoor epoxy resin solids, which have the characteristics of high and low temperature resistance, ultraviolet resistance and aging resistance.
4. The operating mechanism adopts a miniaturized pop-up operating mechanism, which has low energy consumption for opening and closing; the mechanism transmission adopts direct transmission mode, with fewer opening and closing parts and high reliability. The operating mechanism is in a sealed mechanism box, which solves the problem of mechanism corrosion and improves the reliability of the mechanism.
5. The opening and closing operations of the circuit breaker can be operated manually or electrically or remotely. It can be matched with the controller to realize power distribution automation, and can also be combined with the recloser controller to form a recloser.
6. The circuit breaker can be equipped with two-phase or three-phase CT for automatic over-current tripping protection and intelligent control for information analysis. .
7. The circuit breaker can be equipped with isolating switch and three-phase linkage. There is an obvious visible fracture when the isolating switch is in the off state, and it has an anti-mistake interlock with the circuit breaker body. It can be connected with a surge arrester post insulator for easy and safe maintenance.
