ZW43-12 miniaturization outdoor vacuum circuit breaker
  Detailed introduction

1.Product Introduction

ZW32-12 type outdoor high voltage vacuum circuit breaker is the max rated voltage 12kv,50Hz three phase AC outdoor power distribution equipment.Mainly used for the distribution network break,the load current of the closing power system,overload current and the short circuit current.

Use in the transformer substation and industrial and mining establishments power distribution system to realise the protection and contr- ol function.Even be used in the rural power grids and frequent operation place,especially use to meet the urban power network,rural power grid renovation requirements.This installation Instructions shows the main technical parameters,product structure,operation way,installtion methods,use and maintenance theory.

2.Environment for use

2.1.Altitude:no more than 2000m;

2.2.Ambient temperature:-45℃--+40℃;

2.3.Air speed : no more than 35m/s;

2.4.Pollution class:Five

2.5.Installation place:no flammable,explosive,easy corrosion place.

2.6.Earthquake strength:no more than 8 degree.

3.Main features

3.1.The circuit breaker choose the 3 phase pillar type structure,it has the features of the stable and reliable breaking performance,no burny and explosive risk,maintenance-fre e,small valume,light weight and long service life and so on.

3.2.The circuit breaker choose the fully enclosed structure,good sealing performan- ce,help to improve the moistureproof, condensation prevention performance,especially applies to frozen or moist place.

3.3.Three phase pillars and the current transformer choose the import outdoor epoxy resin solid insulator,has the high and low temperature resistance,ultraviolet light resist- ance,ageing resistance features.

3.4.Operating mechanism use the miniaturization spring operating mechanism,switch closing/opening low energy consumption;component driving choose straight moving mode of transportation,small quantity switch closing/opening parts,high reliability.The operating mechanism is placed in the sealed mechanism box,it solves the corrosion problem and improve the mechanism reliability.

3.5.The switch closing/opening of the circuit breaker could use the manual or electirc operation and remote control operation.Could equip the contrller to realise the distribution automation,also could match with the reclosing controller to be the auto recloser.

3.6.The circuit breaker could install two phase or three phase current transformer to realise the overcurrent automatic tripping protection and the information analysis of the intelligent controller.

3.7.The weight of the circuit breaker:<80KG

The overall installation size:695(H)*850(W)*240(D)
