Abstract
The utility model discloses a density relay having an SF6 gas density and micro-water on-line monitoring function. The density relay is composed of a D-type joint capable of performing gas charging and discharging, a C-type joint connected with monitored equipment, an instrument gas chamber, a temperature sensor, a Horsman joint, a pressure sensor, a dew point sensor, and a PCB having a liquid crystal display. The density relay is mounted on a SF6 circuit breaker to realize the SF6 gas density and micro-water on-line monitoring function and is characterized by simple operation, convenience, practicality, and the like.
Description
Technical field
The utility model belongs to SF
6detection device for circuit breaker density monitor technical field of structures.
Background technology
SF
6gas is widely used in high voltage, large capacity, high parameter electric equipment because of its good electric property and stable chemical constitution.At SF
6in electric equipment, the key factor that its electrical strength, arc extinction performance are played a decisive role is SF
6the density of gas, two indexs of micro-water.Due to the monitoring of these two indexs, there are the following problems:
1) be arranged on the SF6 electric equipment, the density monitor that is used for monitoring the SF6 gas density is mostly the mechanical type density monitor.Can send and report to the police and the locking contact point signal when gas leakage occurs the SF6 electric equipment, the operations staff only has the density situation that could understand SF6 gas to on-the-spot, has increased operations staff's workload.
2) monitoring of micro-water can only be tested to scene by testing crew, the situation of change that the operations staff can't Real-Time Monitoring, follow the tracks of micro-water content.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned problem, realizes Real-Time Monitoring SF
6density and micro-water content, and when overproof can and the device of alarm.
The purpose of this utility model is achieved by the following technical solution.
A kind of have a SF
6the density monitor of gas density, micro-water on-line monitoring function, the utility model feature is, comprises D type joint, C type joint, instrument air chamber, temperature sensor, Huo Siman joint, pressure sensor, dew point transducer, forms with the PCB circuit board of liquid crystal display; Its syndeton is, C type joint is arranged on instrument air chamber top, D type joint is arranged on instrument air chamber below, and temperature sensor, Huo Siman joint, pressure sensor, dew point transducer are connected with the instrument air chamber respectively, with the PCB circuit board of liquid crystal display, is arranged on the relay outside.
The utility model is arranged on SF
6on circuit breaker, realize SF
6gas density, micro-water on-line monitoring function.
The beneficial effects of the utility model are: this device adopts totally-enclosed design, and water proof and dust proof is explosion-proof, anti-strong electromagnetic; Be arranged on SF
6on circuit breaker, can realize SF
6gas density, micro-water on-line monitoring; Can also realize real-time monitoring, automation, the digitizing functions such as forecast, data file in advance; And it is little, lightweight, stable, reliable to have volume, the operations staff just can easily correctly check the characteristics such as state of density, micro-water in the distance; And there is the spending of cost-saving and manpower, the characteristics such as greatly increase work efficiency.
Below with regard to the drawings and specific embodiments, the utility model is further explained.

The utility model working method is: C type joint and monitored SF
6after electric equipment connects, the embedded detection system on the PCB circuit board is passed through temperature sensor, pressure sensor, dew point transducer to SF
6the temperature of gas, pressure, dew point carry out the Real-Time Monitoring collection, through certain mathematical analysis and logic judgement, by SF
6the state of gas density and micro-water is in the liquid crystal screen display, and corresponding data is uploaded to network monitoring center by the RS485 wiring.
Display floater is comprised of liquid crystal display screen, LED light, operation push-button.Liquid crystal display screen can show SF
6the temperature of gas, pressure, density, Wei Shui, for extending liquid crystal display screen useful life, reducing power consumption, this device has added acoustic control LCD backlight function, and when near sound equipment surpasses 50 decibels, LCD backlight is opened, automatic distinguishing after 10 seconds.Whether LED light is normally pointed out operation and the communication of complete machine, pressure sensor, dew point transducer respectively.Operation push-button can carry out the setting of parameter and function.
