Product introduction:

 

 

 

This product belongs to integrates light in the field of industrial process control system based on PC, is mainly used in electric power industry, one of the main equipment of SF6 high voltage circuit breaker on-line monitoring and control of SF6 gas, the system of SF6 gas water content, density and temperature of the real-time data acquisition display, the background data and analysis, for the production management of the power system and equipment state overhaul to provide information and basis. Project adopts advanced sensor technology, single-chip microcomputer technology, modern physical analysis theory, control theory and communication technology, and has a number of innovative technology with independent intellectual property rights, such as gas changes in sealing pressure container environment temperature and pressure of trace moisture content and density of continuous detection technique, etc., in power SF6 high voltage circuit breaker SF6 gas micro water and density of the first international online monitoring and control field.

 

 

 

Functional description:

 

 

 

I. product functions:

 

 

 

(1) online monitoring of SF6 gas humidity, density and temperature

 

 

 

(2) the alarm and locking device can be started automatically according to the preset value or the user's given value

 

 

 

(3) automatically draw the state change trend chart

 

 

 

(4) fully sealed, anti-interference, suitable for outdoor environment

 

 

 

Ii. Product features

 

 

 

(1) high precision and reliability

 

 

 

The measuring accuracy of SF6 gas micro water monitor is more than double the national standard. The sensor is corrected and compensated by the internal circuit of the transmitter, and the output linearity is good and the precision is high. The external structure of the transmitter is also more suitable for measurement under the high frequency electric field environment. It is integrated with the circuit processing part to reduce interference coupling and improve the stability and reliability of the circuit in long-term operation.

 

 

 

(2) truly realize online monitoring

 

 

 

The monitor can be hung up for a long time. The communication interface can upload the monitoring data to the monitoring center in real time. When the measured gas index exceeds the standard, the monitor will automatically upload the alarm or blocking signal to the remote monitoring center according to the preset threshold, or directly start the alarm and blocking diagram for observation and analysis.

 

 

 

The application of SF6 gas integrated online monitoring technology can realize the state monitoring of circuit breakers, which is conducive to timely mastering the running state of equipment and ensuring the safe and stable operation of the power system. May reduce system outage time and maintenance costs; Can make the condition maintenance to realize.

 

 

 

(3) unique structure, easy installation and use

 

 

 

The monitor adopts a fully enclosed design with a unique and beautiful appearance. The sensor, power supply, data output circuit and monitoring display are installed in the same housing. It is waterproof, dustproof, explosion-proof, and anti-strong electromagnetic interference.

 

 

 

(4) environmental significance

 

 

 

As a kind of fluoride, SF6 gas is not only one of the harmful gases that destroy the earth's ozone layer and produce greenhouse effect, but also SF6 circuit breaker will decompose a variety of toxic substances after opening, closing and arcing, which will directly affect the physical health of field inspection personnel. The monitor changes the traditional detection method of SF6 and greatly reduces the emission of SF6 gas, which is of great significance for environmental protection to protect the health of staff and reduce environmental pollution.
