Abstract
The utility model discloses a background monitoring system for a gas pressure value of an SF6 breaker. The system comprises a pressure transducer PMR 300, a temperature sensor PT100, a data process system and a background monitoring system, wherein the pressure transducer PMR 300 and the temperature sensor PT100 are arranged in a pipeline of the SF6 breaker, the pipeline being connected with a pressure gauge. The pressure transducer PMR 300 is provided with a processing circuit therein to transform a millivolt signal of a sensor into a standard voltage, current and frequency signal which is outputted to the data process system. The temperature sensor PT100 measures the gas temperature of the SF6 in service, and an outputted signal is transformed into a 0 to 5V standard voltage signal by a temperature transmitting module, then the standard voltage signal is sent to the data process system by a voltage/frequency transformation module. In the data process system, according to the relationship between the pressure and the temperature of the SF6, the standard voltage signal is processed by a software so as to be automatically converted to a voltage value at 20 DEG C. The data is then transmitted to the background monitoring system which can respectively give an alarm or a locking signal in accordance with the different data when the air pressure drops to different degrees.
Description
Technical field
The utility model belongs to breaker technical field, is specifically related to a kind of background monitoring system of SF6 circuit breaker gas force value.
Background technology
The SF6 isolating switch is extensively adopted in electric system, if isolating switch breaks down, will cause very big economic loss; Guarantee the isolating switch reliability of operation; Just must often keep watch on each item index, particularly SF6 gas of isolating switch, it affects the insulation and the arc extinction performance of isolating switch.When leakage of SF6 gas generation at present or pressure are high and low; Low or the low locking divide-shut brake signal of pressure of the SF6 pressure that the operations staff combines to quote on the supervisory system background computer, and watch the manometric concrete condition of SF6 to the scene, just can judge wrong report perhaps pressure problem is really arranged; And actual running environment temperature height influences SF6 pressure; During the walkaround inspection that is in operation, both need write down density (or pressure) value and the environment temperature of SF6 gas, need write down the load current and the temperature rise situation of SF6 isolating switch again; Have only analysis, comparison through various factors; Whether the equipment that just can judge rightly out leaks air or abnormal occurrence such as loop resistance increase, and all these will influence operations staff's correct judgement, has brought certain difficulty for equipment safety operation and walkaround inspection.
The utility model content
The purpose of the utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of can accurately monitor SF6 isolating switch running status, in time find fault, effectively to the SF6 isolating switch keep watch on, the background monitoring system of easy to use, safe and reliable SF6 circuit breaker gas force value.
The technical scheme that purpose adopted that realizes the utility model is: a kind of background monitoring system of SF6 circuit breaker gas force value; Comprise pressure transducer PMR300, temperature sensor PT100, data handling system and background monitoring system; Said pressure transducer PMR300 is arranged on the SF6 isolating switch with temperature sensor PT100 and is connected in the manometric pipeline; Said pressure transducer PMR300, temperature sensor PT100 link to each other with data handling system, and said data handling system links to each other with background monitoring system.
The built-in treatment circuit of said pressure transducer PMR300, said temperature sensor PT100 is provided with temperature transmitting module and voltage/frequency modular converter.
Because the utility model connects at the SF6 isolating switch pressure transducer PMR300 and temperature sensor PT100 is set in the manometric pipeline.The built-in treatment circuit of pressure transducer PMR300 converts the sensor millivolt signal to the accurate Dian Ya of Biao ﹑ Dian Liu ﹑ frequency signal and outputs to data handling system; Temperature sensor PT100 utilizes resistance value to change the temperature that this characteristic is measured SF6 gas in service with temperature variation, and the signal of output is converted into the voltage signal of 0V～5V standard through the temperature transmitting module, gets into data handling system through the voltage/frequency modular converter again; In data handling system; Utilize software, according to SF6 pressure and temperature characteristic relation, the force value when utilizing software processes to be converted into 20 ° of C automatically; Then data are reached background monitoring system; According to the difference of data, when air pressure is low to moderate in various degree, background monitoring system is quoted respectively and is reported to the police or the signal of locking; Thereby judge the actual conditions of SF6 isolating switch in service accurately, thereby in time find fault, effectively the SF6 isolating switch is kept watch on guaranteed that total system normally moves.
