Abstract
The utility model relates to a meter connection of an SF<6> gas density relay, a meter connection body is internally provided with an axis SF<6> gas passage and a Bourdon tube connecting hole communicated with the axis SF<6> gas passage. The connection position of the Bourdon tube connecting hole and the axis SF<6> gas passage is provided with a sensor connecting hole which is perpendicularly communicated with the axis SF<6> gas passage. The inner wall of the sensor connecting hole is a smooth peripheral surface or the inner wall of the sensor connecting hole is equipped with threads. The meter connection of an SF<6> gas density relay not only can realize all the functions of the traditional density relay, but also can realize an independent remote partial system, so a main control room can more conveniently monitor. Therefore, the SF<6>gas density relay and a mechanical portion are independent from each other, thereby increasing the reliability of monitoring the SF<6> gas density, and further guaranteeing the production safety.
Description
Technical field
The utility model relates to a kind of gas density relay meter connector, especially relates to the SF that a kind of high-tension power transmission and transformation equipment is used
6The gas density relay meter connector.
Background technology
SF
6Gas is a kind of good gas insulating material.SF
6Gas has very high electric insulation intensity, stronger arc extinguishing ability, good heat conductivity and excellent thermal stability, therefore is widely used in high-tension electricity devices such as primary cut-out, lightning arrester, mutual inductor, transformer and pipeline bus as insulation and arc-extinguishing medium.Electric elements are being filled with SF
6Work in the closed container of gas, SF
6The density value of gas has direct influence to the electric property of electric elements, particularly insulation and arc extinguishing ability.Therefore, to SF
6The monitoring of gas density and control are the important research directions of guaranteeing the power equipment safety operation.
At present, generally adopt pointer SF on the high-voltage electrical equipment
6Gas density relay monitors SF
6The variation of gas density.In fact this density monitor is exactly a kind of follow-on electro connecting pressure gauge.It mainly is made up of elements such as bourdon tube pressure gauge assembly (comprising joint, Bourdon tube and gear drive etc.), temperature compensating element, electric contact, indicating device (comprising index dial and pointer) and terminal boxes.This density monitor just shows following weak point gradually: 1, can not in real time density value directly be sent to master-control room, for maintenance on duty makes troubles; 2, when variation of ambient temperature, the deformation of temperature compensating element needs certain cycle, can not be synchronous fully, there is certain deviation.
The utility model content
The purpose of this utility model provides a kind of processing simple in structure, easy, has the remote transfer signal output function, is convenient to realize the SF to the real-time Centralized Monitoring of measurement point of a plurality of dispersions
6The gas density relay meter connector.
For achieving the above object, the technical solution adopted in the utility model is: a kind of SF
6The gas density relay meter connector is provided with axle center SF in the meter connector body
6Gas passage and with axle center SF

6Gas density relay meter connector, the inwall of described sensor connecting hole are smooth periphery.
Above-mentioned SF
6The gas density relay meter connector, the inwall of described sensor connecting hole is provided with screw thread.
The beneficial effects of the utility model are:
1, the utility model SF
6The gas density relay meter connector, be on the joint of existing density monitor, to be provided with the connecting hole that is complementary with temperature, pressure transducer, not only can realize the repertoire of traditional density monitor, and can realize independently teletransmission part system, the master-control room of being more convenient for is monitored in real time.
2, use meter connector of the present utility model, make SF
6Gas density relay and mechanical part do not disturb mutually, have increased SF
6The reliability of gas density monitoring has further ensured production safety.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
