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.

Working conditions

2. Altitude: no more than 2,000 meters;
3. Wind speed does not exceed 34m/s;
¨ Vibrations or ground movements from outside the switchgear and control equipment are negligible;
4. Pollution level: Level IV;
5. Storage temperature -40℃~+85℃.

(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.
