- Product Details
JZXC-16/16 is a dedicated multiplexer used to close and open the signal control circuit. It is an important part of railway signals. It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system.
The JZXC-16/16 (formerly known as JZXC-16F) rectifier relay has a high return coefficient, which is used to automatically block the signal lighting circuit of the interval and solve the problem of large leakage current in long-distance power supply cables and unreliable release of the filament supervision relay.
1. The relay is a heavy elastic DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.
2. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay.
4. The front ring of the relay is a diode-enclosed short-circuit coil, without a rectifier unit, and the AC power supply is directly connected to the coil, which has a certain anti-lightning function.
5. The relay contact system consists of common contacts, with four groups of common contacts for switching on and off.
6. The relay should be used in conjunction with the isolation transformer to adjust the system current to ensure the reliable operation and release of the relay, and to ensure that the lamp terminal voltage meets the specified adjustment range.
Insulation withstand voltage
Under the standard atmospheric conditions of the test, the insulation resistance of the relay should not be less than 100MQ.
Under the condition that the air pressure is not lower than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz, 2000V rms voltage, there should be no breakdown flashover after 1min, the voltage when repeating the test Should be 75% of the original test voltage value.
