JPXC-1000偏极继电器不仅广泛应用于场间联系电路、站间联系电路、计算机联锁电路,而且在道岔表示电路中也作为定位表示继电器DBJ和反位表示继电器FBJ使用。出厂时由于JPXC-1000动接点片预压力太小,易造成拉杆断裂后动接点与前接点接通,信号显示升级,违背故障-安全的原则,危及行车安全,所以该问题必须加以解决。下面以车站接近区段电路中1JGJ(JPXC-1000)为例进行说
JPXC-1000 Polarization Relays are not only widely used in field contact circuits, station contact circuits and computer interlocking circuits, but also used as positioning indication relay DBJ and anti-position indication relay FBJ in the circuit of the switch. Due to the JPXC-1000 contact piece pre-pressure is too small at the factory, it is easy to cause the movable contact of the tie rod to be connected with the front contact after the breakage of the tie rod, and the signal display is upgraded contrary to the principle of fail-safe and endanger traffic safety. Therefore, this problem must be solved. The following section of the station near the circuit 1JGJ (JPXC-1000) as an example to say
