I.Product introduction

Central cabinet wireless nuclear phase meter（Hereinafter referred to as " Instrument"）Used for nuclear phase of switch cabinet with five - proof cabinet function，By tying the collector to the busbar of the upper and lower knife switches of the central cabinet, the six-phase measurement can be realized.。At the same time，The instrument is also equipped with a universal transmitter，For two high-voltage lines grid-connected or ring network core phase。The instrument is suitable for 5V ~ 220kV AC transmission lines and secondary charged display nuclear phase，At the same time, it has the function of high voltage test.

The instrument uses wireless transmission technology，Safe and reliable operation，easy to use，Overcome many shortcomings of wired nuclear phase instrument，In addition, the instrument can be upgraded phase sequence detection and remote nuclear phase functions.

II.Safety matters

1、During field testing，It should be operated according to the safety distance standard of the high voltage test of the power department。

2、Standard configuration insulation rod 3 meters，The corresponding voltage level is ≤ 220kV。If the measured line voltage is higher than 220kV，Please use insulating rods longer than 3 meters。

3、During nuclear phase operation，Wear insulation gloves when installing the collector。

Notice：The transmitter uses a 3.7V rechargeable lithium battery，Please do not replace other batteries at will。
