|Product Introduction
JWJXC-H80/0.06 stepless enhanced contact slow release relay is the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the switch, lock and unlock the path, and control the opening and closing of the signal machine. Relays are widely used in railway signal technology, called signal relays, which are important components in railway signal technology. 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 reliability of the relay action directly affects the reliability and safety of the signal system.
Product Usage
The JWJXC-H80/0.06 type stepless enhanced contact slow release relay is used as a switch-start relay in the switch control circuit of a high-power DC electric point machine (such as ZD7-C165/250). The relay strengthened contacts are specially designed for signal circuits with larger on-off power.
Features
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. The use of silver-silver oxidation requires contacts, 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 installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetization, and ensure the reliable fall of the relay.
4. The magnetic circuit system is basically the same as the JWXC-H340 relay.
5. The relay contact system consists of two parts: ordinary contacts and reinforced contacts. There are two groups of moving on and off conversion ordinary contacts; there are two groups of moving on and off conversion reinforced contacts with magnetic arc blowers, and two groups without magnetic arc blowers. The dynamic break conversion strengthens the contact. The structure of ordinary contacts is the same as that of non-polar relays, and the strengthened contacts are specially designed high-power contacts and isolated isolation devices.
6. The rated voltage of the front ring of the relay is DC 24V; the rated current of the rear ring is 11A.

Structural characteristics
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 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 sp
