Jwxc-1000 Type Infinite Relay

product description

JWXC-7 type infinite relay is a relay widely used in railway signal technology, called signal relay, and it is an important part of 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 JWXC-7 type infinite relay is used as a general purpose and air-proof step-down relay in the signal circuit.



Applicable environment

The applicable environment of the relay is:

a) Ambient temperature: -40~+60;

b) Relative humidity: not more than 90% (temperature +25);

c) Air pressure: not less than 70kPa (equivalent to below 3000m above sea level);

d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm;

e) Working position: horizontal;

f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.



product structure

Infinite relay is the typical structure of AX series relay, which is composed of electromagnetic system and contact system. The electromagnetic system includes coils, iron cores, vehicle irons and armatures. The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil. The use of dual coils is to enhance the flexibility and flexibility of the control circuit, which can be controlled by a single coil or a series of double coils according to the circuit needs. The armature is fixed on the blade of the yoke by a butterfly-shaped steel wire, which is flexible in movement. There is a heavy hammer in the transmission part of the Yantie to ensure that the relay armature returns reliably by gravity. The number of weights installed is determined by the structure of the relay contact system, and should be able to ensure the reliable release of the relay. 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 of the relay, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure that the relay falls reliably. The iron core, vehicle iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence.

Product Introduction

JPXC-1000 biased pole relay is an important component in interlocking equipment and the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the way, 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 JPXC-1000 biased pole relay is designed to identify the polarity of the current in the signal circuit. In the signal circuit, it is used in the turnout indication circuit and the single-multiplex semi-automatic blocking circuit.



Features

1. The relay adds a pole-biased magnet to the magnetic circuit, so that the armature is biased to the drop position by the permanent magnetic force. The pull-up of the armature is related to the polarity of the current in the coil. When the current through the coil is in the specified direction, the armature is pulled up, and when the direction of the current is opposite, the armature remains stationary. It only has a stable state, that is, after the armature is sucked up by electromagnetic force, it will fall when the power is cut off, and it will always be in a falling positioning state.

2. The relay is a heavy spring force DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is powered off.

3. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.

4. 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 magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay.

5. The relay contact system is composed of ordinary contacts, with 8 groups of ordinary moving on and moving off conversion contacts.

6. The rated voltage of the relay is DC 24V.
