[power relay]JZ-4 Type Anti High Frequency Electromagnetic Wave Interference Medium Power Relay

2026-6-11 19:00:44

1�� Purpose:
JZ-4 type is a lock key electromagnetic relay that can work normally in high-frequency electromagnetic wave environments without misoperation. Used for signal indication and protection in power network equipment, high-frequency equipment, electromagnetic interference equipment, automatic control or communication equipment.
The characteristics of this relay are its sturdy structure, strong vibration resistance, and dual-use of AC and DC. The contact system has four sets of contacts (3-4, 5-6, 7-8, 9-10). When the button is pressed, the teeth on the armature lock the disc on the moving contact shaft, causing contacts 3-4, 7-8 to close and contacts 5-6, 9-10 to open. When the relay armature is engaged, the source disk disengages and the moving contact shaft quickly resets, causing contacts 5-6, 9-10 to close and contacts 3-4, 7-8 to open. If you want to reuse it, you must press the button again so that it can repeat the above actions.

[power relay]GG-21 type reverse power relay

2026-6-11 18:57:47

1 Purpose
The GG-21 reverse power relay is capable of disconnecting the AC generator from the power grid when reverse power occurs.

Overview of Structure 2
Reverse power relay operates based on the principle of induction (with a rotating magnetic field).
The magnetic conductor of the relay consists of two magnetic circuit systems: an upper magnetic circuit system and a lower magnetic circuit system. The current coil is installed in the upper magnetic circuit system and is powered by a current transformer connected to a certain phase of the generator. The voltage coil is composed of two coils connected in series and installed on the lower magnetic circuit system. It can be directly or through a voltage transformer connected to the generator phase voltage.
The relay rotation system has an aluminum disc, which is pressed onto the shaft, and the two ends of the shaft are pressed into steel shaft tips. The rotation system is supported by steel balls through the shaft tips, which are mounted on bearing screws.
A gear is installed on the aluminum disc shaft, which meshes with the gear equipped with a relay moving contact. A balance spring is pressed onto the moving contact gear shaft to establish a reaction torque.
The silver static contacts are fastened between thin bronze sheets and mounted on a plastic seat. The screws used to install the contact seat are used to adjust the position of the relay static contacts. When reverse power occurs, a torque is generated on the disc to close the relay contacts. Under the action of the aluminum disc rotation torque, the relay contacts close, the generator automatic switch trips, the relay coil loses power, and the relay rotation system returns to its original position under the action of the balance spring.
Relays can change power settings by changing the number of turns of the current coil connected to the current transformer. The current coil tap is welded to the socket, which has three sockets. At rated voltage, the corresponding rated power percentages are 6.4, 9.6, and 12.8.

The GG-21 reverse power relay can be plugged into the corresponding socket for setting the power of a certain action.
In order to prevent the secondary winding of the current transformer from disconnecting and dangerous high voltage at the terminal, there is a spare plug in the fourth socket.
When converting loads, it is necessary to first insert the spare pin into the socket according to the required operating power. Only after doing so can the first pin be unscrewed and placed into the empty socket.
The relay has a delay that is inversely proportional to the operating power, which is obtained by rotating the aluminum disk of the relay rotation system between the permanent magnet poles of the relay.
By changing the stop block of the relay's moving contact, the set value of the action delay can be altered.
The stop lever is made in the shape of a pointer and can move along the dial. The dial is engraved with readings of 2s, 3s, 7s, 9s, and 12s. The time characteristic curves of 2s, 7s, and 12s are shown in Figure 2
When the contact is closed, the steel stop block located on the moving contact reaches the small magnet installed on the bottom plate of the contact system, thus
Attracted it, ensuring the reliability of circuit contact closure.
The relay magnet, rotating system, and contact system are installed on an aluminum silicon alloy frame, which in turn is mounted on an aluminum silicon alloy base. There are two terminal blocks on the base for connecting wires to relay coils and contacts, and the base is also used to secure relays to the distribution panel.
The relay has a steel casing to protect the mechanism from mechanical damage and prevent water droplets from entering.
The internal wiring of the relay is shown in Figure l
