ZW32 Outdoor Column Vacuum Circuit
ZW32 outdoor column vacuum circuit breaker (below) is an outdoor high voltage power 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 system. It is suitable for protection and control in substations and distribution systems of industrial and mining enterprises. It is more suitable for places where urban and rural power grids are built and frequently operated.
ZW32 vacuum circuit breaker is equipped with a spring energy storage operating mechanism, which can be manually operated, electrically operated and controlled by remote control. The isolation switch can be installed on the side of the circuit breaker to form an outdoor high-voltage vacuum circuit breaker and an outdoor high-voltage disconnecting switch assembly, which increases the visible isolation fracture and has a reliable interlocking operation. According to the user's requirements, it can cooperate with the corresponding controllers to form AC high-voltage vacuum reclosers, automatic segmenters, and self-provisioned power supply. It is the ideal equipment for the automation of distribution networks. The structure of high voltage voltage transformer is external and can be installed integrally. ZW32-12G/1250-20, ZW32-12 series of column type outdoor high voltage vacuum circuit breaker is a three-phase AC 50hz, rated voltage 12kv outdoor high-voltage switchgear. Suitable for breaking, closing load currents, overload currents and short-circuit currents in urban or rural distribution systems. Circuit breaker is a new miniaturized design, fully enclosed structure, a unique arc extinguishing chamber packaging technology, good sealing performance, moisture-proof, anti-condensation, suitable for high temperature and humid areas. zw32-12G circuit breaker disconnector combination is composed of two parts of zw32 circuit breaker disconnector.

2, the ambient air temperature: upper limit +30 °C, lower limit -40 °C;
3, the wind pressure does not exceed 700Pa (equivalent to a wind speed of 34m/s);
4. Amplitude: Violent vibration;
5, antifouling grade III
Switch structure features
1. The three-phase pillar structure of the circuit breaker has the characteristics of stable and reliable breaking performance, 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 and has good sealing performance, which helps to improve the moisture-proof and anti-condensation performance, and is particularly suitable for use in severe cold or humid areas.
3, three-phase pillars and current transformers imported outdoor solid epoxy resin insulation, or the use of epoxy resin in the user outsourcing organic solid silicone insulation; with high temperature resistance, UV resistance, anti-aging characteristics.
4. The operating mechanism adopts a miniaturized spring operating mechanism. The power of the energy storage motor is low, and the energy consumption of the sub-switching and closing is low. The mechanism transmission adopts the real-motion transmission method, and the number of parts is small and the reliability is high. The operating mechanism is placed in a sealed mechanism box to solve the problem of corrosion of the operating mechanism and improve the reliability of the mechanism.
5, the circuit breaker's split, closing operation can be manual or electric operation and remote remote control operation. It can be combined with intelligent controllers to realize distribution automation, and can also be combined with reclosing controllers to form automatic reclosers and segmenters.
6. The circuit breaker can be installed with two-phase or three-phase current transformers for over-current or short-circuit protection, and it can also provide the intelligent controller with current acquisition signals; according to the user's requirements, it can be equipped with a metering current transformer.
7. The circuit breaker can be externally connected with a three-phase linkage isolation switch. The disconnector can be clearly seen under the open state of the disconnector, and it can be equipped with an anti-misoperation interlocking device between the circuit breaker body. Only when the isolation knife is completely closed or completely The breaker can only be operated when it is opened. It can install lightning arrester post insulators for easy maintenance.
