ABB circuit breakers are widely used in industrial fields. It has played a good role in protecting those complex systems and electronic circuits. Installing abb circuit breakers can effectively prevent failures. It can quickly restore and operate conditions. Provide a best solution, so ABB circuit breakers have a very important position in the industry.
I. Installation and use of ABB circuit breakers
1. The installation of ABB circuit breakers must be carried out in strict accordance with the instructions.
2. Pay special attention to the tightening torque of the bolts.
3. No empty operation is allowed, and it is not allowed to operate when the pole is not installed. It can only be operated when the operating mechanism is successfully connected to the circuit breaker and the circuit breaker is adjusted to a certain pressure.
4. When charging, do not press the contactor manually.
5. When opening and closing, do not touch the release manually.
6. When testing the lowest operating voltage of the coil, the jog test should be performed.
7. When testing the main circuit resistance, the test current should be greater than or equal to 200A.
8. The respective phases of the circuit breaker and the power system do not need to correspond.
Notes on using II.abb circuit breaker
1. Before using ABB circuit breakers, read the product manual carefully, and perform operations in strict accordance with the relevant steps of the manual.
2. Pay special attention to the relevant safety regulations in the manual.
3. In the process of use, once any problem is found, do not solve it without authorization, and contact relevant ABB personnel in time to solve the problem most effectively instead of expanding the fault.
4. If working on the porcelain sleeve of the circuit breaker, reduce the pressure to 0.125MPa, otherwise the porcelain sleeve may be damaged.
5. If necessary, disconnect the circuit breaker power supply and ground, or disconnect the motor circuit, or disconnect the control voltage, etc.
III. Maintenance of ABB circuit breakers
For ABB circuit breakers, it is a good idea to regularly check the internal performance. Such as: operation counter inspection, spring energy storage inspection, sub-brake detent inspection, anti-corrosion inspection, lubrication inspection, mechanical characteristic inspection, operation test, anti-jump circuit inspection, switch position verification, thermal imaging inspection, buffering device inspection, etc.
