Product Introduction
SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field it is often found that the operation is not flexible and the contact contact is not good after a period of time and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly the SF6 density relay often misoperates.Therefore DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation.
The check pressure sensor with high precision and high speed A/D converter combining with the 32 bit high performance microprocessor can check the performance of A variety of SF6 gas density relay can accurately measure the movement of the signal when the current temperature pressure value arbitrary automatically when the environment temperature of 20 â?? conversion standard pressure and have A print store and U disk offload function at the same time the fault in the process of automatic identification test.Sf6 gas density relay calibrator is convenient to carry simple to operate high test accuracy strong stability and good reliability which reflects the characteristics of "intelligent" instrument.

Introduction The LWâ?¡-252/4000-50 self-extinction Ac circuit breaker which is outdoor type finds its universal range of applications for the electrical system with elevation not greater than 2000m, ambient temperature not lower than-30C, dirtiness grade not higher than IV, alternating current 50Hz and the maximum voltage 126kV. It is used for cutting the rated current, malfunction current or switching the circuitry, to control and protect the electrical system, and it can also be used for connecting with the circuit breaker The gas of the SF6 is employed as the arc-extinguishing medium and the dielectric material. The self-extinction technology and the new-type spring operating mechanism are introduced in the SF6 circuit breaker. Thus the circuit breaker has good qualities with long electrical life, low operation power, lower noise, high reliability, simple structure, small and long overhaul periods. It can fully replace the import same type one. Caracteristic of structure The breaker introduces the three-phase porcelain -pole with single interrupter structure. A spring operating mechanism is supplied and the mechanical action of the three-phase is inner connected. The gas of the SF6 is connected in the three-phase pole parts. A density controller with temperature compensation is used to monitor the gas of the SF6. Because of the self-extinction arc control principle and optimized design, it improves the efficiency of mechanism and reduces the operating power Excellent breaking performance and long electrical life High mechanism reliability and can be operated frequently Because of the high insulation intensity and excellent contact movement, the breaking capacity current will not re-burn The circuit breaker has high outer insulation level and ratio creepage distance is greater than. So it has excellent performance of resisting the filth and the earthquake, it is also can be operated safely under the environment with atrocious weather High carrying ability: it has high capability margin as the temperature of each contact rises when it is under temperature rise test in the circuit (1.2 times 0f 4000A) The appearance of the breaker is compact, and the installation and debugging is very easy. The maintenance is also very convenient
