ZW32-40.5kV Outdoor Pole Mounted Vacuum Circuit Breaker 35kV Auto Recloser

ZW32-40.5 series outdoor high-voltage vacuum circuit breakers are used in three-phase power systems with AC 50Hz and rated voltage of 35kV, as a means of separating and combining load current, overload current and short-circuit current. The circuit breaker can be equipped with reclosing controller to identify the current characteristics and achieve multiple automatic reclosing, self-provided PT as a power source to become an intelligent circuit breaker with voltage and current signal output and can be controlled; by the electronic PT to provide power and can complete the overcurrent delay, inrush current delay, short-circuit quick-break three-stage composite protection.

ZW32-40.5 outdoor high-voltage vacuum circuit breaker is mainly composed of integrated sealed pole,current transformer,operationg mechanism and box body. This type of circuit breaker is miniaturized,and its shell is made of high-quality steel box.Current trasformers can be selected according to users' needs. ZW32-40.5 outdoor high-voltage vacuum circuit breaker and matching intelligent control combination.On-off operation of switch can be realized locally,and it can also be operated by remote control through communication interface.Other information of the circuit breaker can also be transmitted to the control center,and the communication channel can be cable,optical fiber.GPRS/CDMA,GSM,etc.

Features

(1) ZW32-40.5 series of products overall for the pillar type, three-phase common mounted on a mechanism box, the dynamic end of the interrupter room through the inflection arm, insulated tie rods for the output shaft of the mechanism connected. The mechanism and the connecting rod connected with the circuit breaker are in a waterproof box. The transmission mechanism of the circuit breaker is composed of a connecting rod and a crutch arm, and the dynamic end of the interrupter chamber is connected to the output shaft of the operating mechanism through a crutch arm, an insulated tie rod, a connecting rod and an operating mechanism. The rotation of the output shaft is driven to realise the dynamic contact of the arc extinguishing chamber to carry out the splitting and closing action.

(2) ZW32-40.5 series products are equipped with current transformer, each phase can take four windings, two of which are used for measurement, two for protection. According to customer’s need, 100:5, 200:5, 400:5, 800:5, 1000:5, 1600:5 current transformer can be installed.

(3) Disconnecting switches can be added to the side of the circuit breaker to form an outdoor high-voltage vacuum circuit breaker and an outdoor high-voltage disconnecting switch combination appliance, which increases the visible disconnecting breaks and has reliable interlocking operation.
