Description
Technical field
The utility model belongs to the HF current transformer that test is put in a kind of office of being used for.
Background technology
In the converting station high voltage electrical apparatus local detection, the high-frequency current signal that can flow through the ground wire of high voltage electric equipment when high voltage electric equipment generation office is put detects in the high voltage electric equipment office puts situation, avoids the generation of accident.But lack portable, on-the-spot operation and the high equipment of detection efficiency fast of being beneficial at present.
Summary of the invention
The purpose of the utility model is that the HF current transformer of test is put in a kind of office of being used for of design, has to be easy to carry, and field wiring is oversimplified; Be easy to charged installation and dismounting, have simple in structure, safety; Easy to operate, time saving and energy saving, improve detection efficiency and the good advantage of result of use.The utility model mainly is made up of housing and irony circle, and housing is made up of two semicircular in shape circular shells, is provided with the irony circle in the housing, connects caliper body to be opened/closed with the elasticity hinge between the two housings, and housing one side is provided with the circuit box body.Described circuit box body is provided with output signal socket.The said structure design has realized the purpose of the utility model.
The utlity model has and be easy to carry, field wiring is oversimplified, and is easy to charged installation and dismounting, have simple in structure, safety, easy to operate, time saving and energy saving, improve detection efficiency and the good advantage of result of use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the HF current transformer of test is put in a kind of office of being used for, and mainly is made up of housing 2 and 6 on irony circle.Housing is made up of two semicircular in shape circular shells, is provided with the irony circle in the housing, connects caliper body to be opened/closed with elasticity hinge 3 between the two housings.Housing one side is provided with circuit box body 5.Circuit in the circuit box body comprises irony ring signal receiving circuit, signal processing circuit and signal output apparatus.Described circuit box body is provided with output signal socket 4, is used to connect line trap and detection signal is transported on the computer-controlled detecting instrument is handled.Two semicircular in shape circular shell middle parts form lasso mouth 1, can conveniently housing be set on the ground wire of electrical equipment.
During use; Housing is set on the ground wire of electrical equipment; The line trap of computer-controlled detecting instrument is plugged in the output signal socket of circuit box body; When electrical equipment generation office put, the irony circle imported the circuit of signal through the circuit box body in the detecting instrument into, accomplished on-line monitoring inside electric appliance office and put situation.
In a word, the utlity model has and be easy to carry, field wiring is oversimplified, and is easy to charged installation and dismounting, have simple in structure, safety, easy to operate, time saving and energy saving, improve detection efficiency and the good advantage of result of use.
