 Introduction

JN22B-40.5/31.5 series indoor HV earthing switch is researched and developed by XI’AN HV Electric research organization, with advanced design and steady performance,simple structures, simple mounting end adjustment suitable for electric power system with 40 5KV. Three- phase. AC 50Hz.As an earthing protection, it can be used in KYN□- 40.5 or other kinds of switchgears. It is complied with GB 1985-2004 and IEC129 standard.

General

The controlle of YF-DJN-04 earthing switch can realize the control and protection of motor operating mechanism. If the electric mechanism has difficulty in driving the motor, for example the installation is not in place or the mechanism is stuck, which reaches the protection condifion, the controller can break the motor immediately and drive motor reversely to release the stuck state of the chassis.

Introduction

In order to adapt to the development of power swichgear, we developed the electric earthing switch which achieves national invention patent. To maintain the style and the relevant interlock of the original switchgear, the electric earthing switch adds motor operating mechanism on the basis of original earthing switch JN15, JNI7, JN22B and JN22 series.It could maintain the characteristics of the original earthing switch and realize the electric operation of the earthing switch at the same time.And the electric and manual operation do not need to switch, which satisfies the requirement of programmed operation in the power system.

The controlle of YF-DJN-04 earthing switch can realize the control and protection of motor operating mechanism. If the electric mechanism has difficulty in driving the motor, for example the installation is not in place or the mechanism is stuck, which reaches the protection condifion, the controller can break the motor immediately and drive motor reversely to release the stuck state of the chassis.
