Abstract
The invention relates to a sulfur hexafluoride (SF6) density relay transmission test control device which is characterized by comprising a control valve (1), wherein an inlet tube (2) of the control valve (1) is connected with one end of an extension tube (4) through an interconnecting nut (3), and the other end of the extension tube (4) is connected with a live connection nut (5). Trials prove that after the SF6 density relay transmission test control device is used, the problem that an indicator of a SF6 density replay meter gets stuck, or other failures such as normal rotation failure and abnormal connection of connection points during indicating, and potential safety hazards which can not be found in a traditional SF6 density relay transmission test can be found timely, and the problem that transmission of part of breakers fails due to the installation position of an SF6 density relay is solved, and the transmission test from the root of the SF6 density relay is achieved.
Description
Technical field
The present invention relates to a kind of SF6 (is sulfur hexafluoride SF
6) density monitor transmission test control device.
Background technology
Stipulate according to power equipment preventive trial code of practice, before SF6 isolating switch and the GIS putting equipment in service, after the overhaul, will carry out the transmission verification to locking, anti-performance, the signal that jumps and prevent and treat the sub controlling unit such as non-complete mutually combined floodgate in case of necessity, and require transmission test to carry out from root.The present situation of transmission test is at present: SF6 density monitor tail wiring box is opened at the scene, adopts corresponding warning and the locking contact of the artificial short circuit of shorting stub to test.
But for the SF6 density monitor of installation site near isolating switch framework middle part, terminal box wraps in framework inside, even open shrouding, also can't adopt traditional short circuit method to open terminal box and carry out transmission test, can only take to carry out the short circuit test transmission at upper level mechanism case internal wiring terminal row place, like this, for reporting to the police and the locking contact connects anti-defective and also can't find, more have no way of realizing the root transmission test, virtually buried more device security hidden danger.
Summary of the invention
The purpose of this invention is to provide a kind of SF6 density monitor transmission test control device that can realize carrying out from the root of SF6 density monitor the transmission test function.
A kind of SF6 density monitor transmission test control device, its special feature is: comprise operation valve, the induction pipe of this operation valve is connected with an end of extension tube by interconnecting nut, and the other end of this extension tube is connected with the flexible connection nut.
Wherein the two ends of interconnecting nut respectively with the induction pipe of extension tube and operation valve between being threaded, and the equal hermetic seal in junction.
Wherein be flexibly connected between nut and the extension tube to be threaded, and the junction hermetic seal.
Wherein the outlet of operation valve is connected with a tail gas recycle pipe, and the junction hermetic seal.
Through probationary certificate, after adopting control device of the present invention, can in time find SF6 density monitor table meter pointer card plucked instrument or other faults that can not find in traditional SF6 density monitor transmission test, such as can not normal rotation, contact normal defective and the potential safety hazard such as connection not during indication.Solved the part isolating switch because of SF6 density monitor installation site can't transmission problem, realized carrying out transmission test from the root of SF6 density monitor.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of SF6 density monitor transmission test control device, comprises operation valve 1, and the induction pipe 2 of this operation valve 1 is connected with an end of extension tube 4 by interconnecting nut 3, and the other end of this extension tube 4 is connected with flexible connection nut 5.Wherein, the two ends of interconnecting nut 3 respectively with the induction pipe 2 of extension tube 4 and operation valve 1 between being threaded, and the equal hermetic seal in junction, and be flexibly connected between nut 5 and the extension tube 4 to be threaded, and junction hermetic seal.The outlet 6 of operation valve 1 is connected with a tail gas recycle pipe 7 in addition, and the junction hermetic seal.
Using method of the present invention is:
To be flexibly connected nut 5 during use is tightened on the SF6 density monitor checking joint, can use in case of necessity the seal elements such as O-ring seal to make the junction hermetic seal, then close SF6 breaker body operation valve, utilize the residual gas of SF6 density monitor gauge outfit the inside, exit by the operation valve 1 of slow rotation control device of the present invention and just can realize carrying out transmission test from root.
