                                              HVJ6-7.2KV Vacuum Contactor真空接触器

                                              1. Introduction

                                              HVJ6-7.2 series indoor high-voltage AC vacuum contactor has two types: One is Mechanical holding type, the other is Electromagnetic holding type. It is applicable for three-phase AC 50HZ power system of rated voltage 7.2KV and below and rated current up to 630 A to open and close circuit remotely and control electrical equipment like high-voltage motor, transformer and capacitive load. It is especially suitable for fields operated frequently. The contactor uses the international fashionable up and down structure  arrangement and has the advantages of small, light, easy to maintain and form a complete set of F-C circuit equipment.

                                              HVJ6-7.2系列户内交流高压真空接触器(JCZ5-7.2),分为合闸机械保持和电磁保持两种型式。该接触器适用于三相交流50Hz、额定电压7.2kV额定电流至630A的电力系统中,供远距离接通与分断线路,控制高压电动机、变压器及容性负载等用电设备,尤为适用于各种频繁操作领域。该接触器体积小、重量轻,采用当今国际流行的上下布置的组装式结构,使用维护方便,易于组成F-C回路成套设备。

                                              2. Service condition环境条件
