Electronic measuring sensor for ring network cabinet

Abstract

The invention provides an electronic measuring sensor for a ring network cabinet. The electronic measuring sensor comprises a ring-shaped current sensor and a voltage sensor. The ring-shaped current sensor sleeves an outer side of a cable attachment first conductor. The voltage sensor includes a primary mounting end, a film capacitor, and a voltage sensor insulating housing. The primary mounting end is arranged on the top of the voltage sensor insulating housing, and a lower end of the primary mounting end is connected to an upper end of the film capacitor. A lower end of the film capacitor isconnected to a secondary wire outlet terminal of the voltage sensor through a lead wire. The primary mounting end of the voltage sensor is arranged between the first conductor and a second conductorwithin the cable attachment. An upper part of the voltage sensor insulation housing is inserted into the lower part of the cable attachment. The electronic measuring sensor is small in size and simpleto install, and the electric energy measurement can be achieved by directly using an original ring network cabinet. The sensor can be transferred by using a universal cable attachment on the market,and a ferromagnetic resonance failure caused by the magnetic saturation of a transformer iron core and the like is avoided.

Description

technical field [0001] The invention belongs to the field of electronic metering devices for ring network cabinets, in particular to electronic metering sensors for ring network cabinets. Background technique [0002] Due to the limited internal space of the ring network cabinet, it is not suitable to adopt the traditional high-voltage metering scheme to directly use the traditional CT and PT. It must be equipped with a metering cabinet, especially for the transformation project that needs to increase the metering function, and the cost is high. Contents of the invention [0003] The object of the present invention is to provide an electronic metering sensor for a ring main unit, which is small in size, easy to install and easy to use. [0004] The technical solutions adopted are: [0005] Electronic metering sensors for ring network cabinets, including ring current sensors and voltage sensors. [0006] Its technical points are: [0007] The outer side of the loop curre...
