Load switch use and maintenance: 1 After unpacking the packing list and check the product and technical documentation are complete random Xi'an load switch, check the product in the transport, storage process without damage. Dust load switch on the 2 Clear products, and insulators and grounding parts wipe clean. 3 conductive parts and mechanical friction parts, coated with neutral Vaseline. 4 After installation is complete check the wiring is correct, good grounding is reliable. 5 in operation should be regular inspection and maintenance load switch factory outlets, once a year; in breaking 20 times the rated load, it should conduct a comprehensive overhaul. 6 Inspection should not charged in the case, and should check the insulator, the contact exposure and so on. 7 operating personnel must be familiar with all parts of the performance, configuration and installation of the load switch. The essential difference between load switches and circuit breakers is different to their breaking capacity, breaking capacity circuit breaker can be done during the manufacturing process, but high load switch breaking capacity is limited. Load switch plus fuse protection is generally protected only fast break and overcurrent. Mainly by adding breaker with current transformer secondary equipment to protect. Load switch is mainly used in the opening and closing of distribution transformers and small capacity (<800KVA) circuit breaker is mainly used in the regular breaking load of the motor and high-capacity transformers and substations in load switch price |.. Lhasa load switch | Xi'an by the Xi'an High Huayi power plant.
