We are specialty on epoxy resin medium voltage and high voltage components, such as 10KV, 24 KV and 40.5KV Circuit Breaker , Load breaker switch , Disconnecting Switch , Epoxy resin switchgear bushing , contactor box , insulators and transformer . 630A, 1250 A ,2500A , 3150A and 4000A contact box , club contact , fix contact, arm contact and jaw contact . 630A and 1250A VS1 circuit breaker . 630A and 1250A ZN85-40.5 circuit breaker . 12KV and 24KV earth switch. KYN28A-12 and KYN61 high voltage switchgear components .
As mentioned above, the function of the ring cabinet is simple, it is to connect different power parts, generally do not use it to realize the control, protection and measurement of specific electrical equipment; If you really need these things, it must be you choose the wrong, should choose the cabinet; Where there is high pressure, high pressure measurement should be given priority over low pressure measurement; When there is no way to measure it, low pressure measurement is considered. At this point, the low voltage measuring cabinet should be placed in the front of the low voltage entry line, behind the transformer, from the surface, it is not under the protection of Jilianggui, but in general, it should be in the transformer.
So the ring net cabinet is not only used as the contact switch cabinet, but also as the loop in and out of the switch cabinet, measuring cabinet, PT cabinet. Loop-in and loop-out switchgear not only can load switch-fuse combination, but also can load circuit breaker, such as domestic HXGN, Schneider SF6, Siemens 8DH, and second protection can install microcomputer protection device. But the ring net cabinet breaker has the load limit, each factory's ring net cabinet limits are different. If Schneider RM6 ring net cabinet, Transformer high voltage switch protection is greater than 2000 KVA capacity, must adopt circuit breaker + VIP 300 microcomputer protection. However, the load of the in-and-out line of the cabinet is not limited(except the larger load is 1 meter wide).
