Executive standard GB/T7417-2010 "Railway Signal AX Series Relay" product structure The electromagnetic system of the stepless enhanced contact slow release relay is the same as that of the stepless slow release relay (JWXC-H340). The magnetic circuit system of the JWJXC-H125/80 stepless enhanced contact slow release relay adds a copper short-circuit ring to make the slow release time longer. The contact system consists of two parts: ordinary contacts and enhanced contacts. The structure of ordinary contacts is the same as that of non-polar relays, and the reinforced contacts are specially designed high-power contacts and arc wave devices. Product Usage The transmission relay is one of the important equipment in the AC counting code automatic blocking equipment. The DC pulse sent by the electric code transmitter is transformed into an AC pulse by the relay, and then sent to the track circuit. JCZC2-2000 transmission relay is used in the station. Features Heavy spring force relay. It is necessary to install a shock absorber when in use. Mechanical properties Number of contact groups: 2QHJ; 2QH Identification pin number: 14, 53; Strengthen the contact gap: not less than 1.5mm; Ordinary contact gap: not less than 0.8mm; Strengthen the contact pressure: the front contact is not less than 450mN; the rear contact is not less than 450mN; Ordinary contact pressure: the front contact is not less than 250mN; the rear contact is not less than 250mN; The air gap between the iron core and the street iron when the relay is working: not more than 0.20mm.

3. When repairing or replacing the relay, first remove the national relay spring, and then pull out the relay. Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket. Faults and troubleshooting methods 1. The relay contact has no output The analysis and elimination methods of the relay contact without output are as follows: (1) Make sure that the relay and socket should be reliably plugged in; (2) Check that the relay should not be mechanically blocked. If foreign matter in the relay blocks the armature, the armature cannot work reliably (forward rotation) or release (reverse rotation), and the contacts cannot be reliably contacted; (3) Check that there should be no foreign matter between the contacts, there is foreign matter between the contacts, and the contacts cannot be reliably contacted; (4) Check that the contact resistance of the relay contact should not be too large. 2. The relay does not work or the relay with a pole cannot be reversed in the forward direction be reliably released.

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.
