▸ Product Introduction

Description

ZW20-12F outdoor column high voltage vacuum circuit breaker, used for  outdoor high volt. Distribution Switchgear, rated voltage 12kV, three-phase AC 50  HZ. Mainly used for opening, closing the power system load current, overload current  and short circuit current. The main configuration consists of vacuum breaker,  CH-40 controller, external voltage transformer (Note: distribution automation  line ring network available in bilateral PT) three parts. 

This product are widely used in 10kV, 13kV city, rural power grid space  ring network for disconnecting  switch, contact switch, automatic switch device which can implement the ring  deployment line load.

It uses vacuum arcing SF6, N2 mixed gas as dielectric, to introduce the  Toshiba VSP5 gas seal, explosion, insulation structure technology, the overall  excellent sealing performance. Inside is filled with SF6, N2 mixed gas which  does not leak, not affected by the external environment. The spring operating  mechanism with miniaturization and performance optimization design, action  reliability is much higher than the traditional spring mechanism 


Product Feature

1.Ideal apparatus in urban and rural electricity network reform:Remote function:remote control,remote metering,remote communication and remote adjustment.

2.Flexible operating:Both power storage and CO operation are motor and manualoperated,remote and local operation are both available.

3.Excellent breaking capability:Break short-circuit current 25kA up to 30 times.

4.Small operation power and high dependability:The small motor-driving springoperation mechanism with new design is of lowest operation power (about 30W).

5.Multiple installations:Pole mounted and pad mounted.

6.Reliable sealing:The mature sealing technology assures reliable sealingperformance

7.Particular incoming and outgoing method:Silicon rubber bushing to make enoughinsulate distance.

8.Safe operation:Anti-explosive device mounted on the top of box preventsheated gas and maters from spattering out when inner fault occurs.


Ambient condition

1.Ambient Temperature:-40℃~+40℃

2.Altitude:≤2000m

3.Wind Pressure:no more than 700Pa(equal to 34m/s wind speed

4.Maximum Temperature Drop:no more than 25℃

5.There will be have dew under the condition of high temperaturelow down hastily.
