4、 Structural characteristics

The CJX1 AC contactor is a direct motion mechanism with double break point contacts, featuring three pairs of normally open main contacts and auxiliary contact combinations as shown in the table below. The CJX1 contactor contact support and armature adopt elastic locking and connection, eliminating weak links. The action mechanism is flexible, manual inspection is convenient, the structural design is compact, and it can prevent external debris and dust from falling into the moving parts. The wiring terminals have protective covers, and hands cannot directly contact live parts. The CJX1 contactor has small external dimensions and a small installation area. The installation method can be installed with guide rails or fastened with screws. Compared with other similar products, it has a higher operating frequency and control capacity. The product is safe and reliable, and is an internationally advanced contactor model.

5、 Application and maintenance of CJX1 AC contactor

5.1 Inspection items during operation:
5.1.1 Whether the load current passing through is within the rated value of the contactor;
5.1.2 Whether the opening and closing signal indication of the contactor matches the circuit status;
5.1.3 Check if the operating sound is normal and if there is any discharge sound due to poor contact;
5.1.4 Check whether the electromagnetic coil is overheated and whether the short-circuit ring of the electromagnet is abnormal.
5.1.5 Check for looseness and damage to the arc extinguishing hood;
5.1.6 Check for burnt auxiliary contacts;
5.1.7 Whether the transmission part is damaged;
5.1.8 Check for any unfavorable operating factors in the surrounding environment, such as excessive vibration, poor ventilation, and excessive dust.
During maintenance work on electrical equipment, the contactor should also be maintained.
5.2.1 External maintenance:
a. Clean up external dust;
b. Check if all fasteners are loose, especially the conductor connection parts, to prevent contact looseness and heat generation;
5.2.2 Maintenance of Contact System:
a. Check if the positions of the moving and stationary contacts are aligned, and if all three phases are closed simultaneously. If there are any issues, adjust the contact springs;
b. Check the degree of contact wear, the depth of wear should not exceed 1mm. If the contact is burned or detached during welding, it must be replaced in a timely manner; When slightly burned, it generally does not affect use. When cleaning the contacts, sandpaper is not allowed and a shaping file should be used;
c. Measure the insulation resistance between phases, with a resistance value not less than 10M Ω;
d. Check whether the auxiliary contact is flexible in action, the contact stroke should meet the specified value, and check whether the contact is loose or detached. If any problems are found, they should be repaired or replaced in a timely manner.
5.2.3 Maintenance of iron core:
a. Clean the dust, especially between the moving parts and the contact surface of the iron core;
b. Check the fastening of the iron core, loose iron core can cause increased operating noise;
c. The iron core short-circuit ring should be repaired in a timely manner if it falls off or breaks.
5.2.4 Maintenance of Electromagnetic Coil:
a. Measure the insulation resistance of the coil;
b. Check for discoloration and aging of the coil insulation, and the surface temperature of the coil should not exceed 65 ° C;
c. Check the connection of the coil leads, and repair them in a timely manner if there is any soldering or burning damage.
5.2.5 Maintenance of arc extinguishing hood:
a. Check if the arc extinguishing cover is damaged;
b. Is there any looseness or change in the position of the arc extinguishing hood;
c. Remove metal particles and debris from the gaps in the arc extinguishing hood.

6、 CJX1 AC contactor contact system:

The main and auxiliary contact materials are composed of silver alloy with superior electrical performance, which has a long service life and good contact reliability. The arc extinguishing chamber is enclosed and equipped with flame-retardant materials to prevent the arc from splashing outward. There is no arc extinguishing baffle for Ie ≤ 22A, and a metal baffle for Ie ≥ 32A to ensure the safety of personnel and nearby electrical appliances. The wiring screw adopts a new type of self lifting screw, and the tile shaped pad and screw are not separated, which can save wiring time.

7、 CJX1 AC contactor magnetic system:

The electromagnetic system is reliable in operation, with low loss and noise, and has high mechanical strength. The wiring terminals of the wiring diagram are equipped with voltage specification labels, which are painted with specific colors for clear and eye-catching voltage levels. The wiring is convenient and can avoid coil burnout caused by incorrect voltage specifications.

8、 Installation position of contactor:

The contactor must be installed on a vertical surface at the position shown in the diagram.
