100A / 630A how Explosion-proof circuit breaker breaker maintenance <br> <br> / Explosion-proof circuit breaker or three anti-breaker is a more commonly used in industrial electrical control circuit production / oil and chemical; and in use In the course of the process, there are a lot of problems and fault repair operation problems. If we can do maintenance work during the daily use, our explosion-proof circuit breakers will reduce the damage and damage during use. occur.
First of all, we know the explosion-proof circuit breaker that we have just mentioned: explosion-proof circuit breaker cast aluminum alloy shell, surface spray, explosion-proof anti-corrosion circuit breaker for plastic injection molding, built-in circuit breakers. Or leakage circuit breakers. Http://
Learn about routine maintenance work and steps for explosion-proof circuit breakers:
First, check the outside for dust and defects. Regularly sweep the dust and keep the circuit breaker clean.
Second, check whether the load exceeds the rated value of the circuit breaker.
Third, check whether the contact wires of the contacts are overheated.
Fourth, check the fastening bolts are tightened.
5. Check and verify the correct setting of the trip unit; check whether the thermal components are damaged and whether the gap is normal.
6. Check whether the connecting rods, shaft pins, and springs of the operating mechanism are deformed, rusted, and defective, and whether the operation is flexible. 7. Check whether the indicator light of the minute and closing status is correct.
Eight, monitor automatically switch whether abnormal noise in operation.
Nine, open the shell to check whether the position of the arc cover moves due to vibration, whether the arc cover has been dampened and burned by the arc. The damped arc extinguishing cover should be dried; when there are smoke marks and metal slag on the surface, the knife can be used. Or fine-trimming and scraping; if the burning of the arc extinguishing grid is serious or the arc-extinguishing cover is cracked, it should be replaced immediately to avoid interphase short-circuit accidents.
10. Check whether the surface of the electromagnet has oil stains, dust, whether the coil is overheated and scorched, and whether the spring has traces of rust.
After reading the above introduction, we have a preliminary understanding of the maintenance and repair of explosion-proof circuit breakers and circuit breakers. How to maintain the explosion-proof circuit breaker after use? How can I ensure that explosion-proof circuit breakers are used safely and correctly?
All kinds of electrical appliances have an end-of-life, which is what we often say, such as the lighting switch we talk about his number of switches, the battery we say it cycles the number of times or the number of discharges, if there is not a science in a good product The effective maintenance, its service life will also be greatly reduced, which is why there are many users how to respond to how long it has not been on a variety of small problems, the above is my company on the explosion-proof circuit breaker related technology introduction, hope that everyone can Reference reference to ensure the normal use of the product.
