This series of products is a complete set of equipment for receiving and distributing electric energy and/or for generator outlet protection in three-phase AC power grids with rated voltages of 7.2 to 12 kV and below and rated frequency of 50 Hz. This product is equipped with a generator outlet circuit breaker and can be used for the control and protection of the generator outlet side in small and medium-sized generator sets-transformer wiring units, and meets the parameter requirements of the transformer side as a short-circuit source. It can also be used for the control and protection of high-current circuits on the medium-voltage side of power systems.
Product name:
KGN7 series double busbar fixed AC metal-enclosed switchgear
Product introduction:
This series of products is a complete set of equipment for receiving and distributing electric energy and/or for generator outlet protection in three-phase AC power grids with rated voltage of 7.2~12kV and below and rated frequency of 50Hz. This product is equipped with generator outlet circuit breakers and can be used for small and medium-sized generator sets; - control and protection of the generator outlet side in the transformer wiring unit, and meet the parameter requirements of the transformer side as a short-circuit source, and can also be used for the control and protection of high current circuits on the high-voltage side of the power system.
Product features:
1. The double busbar cabinet has two sets of main busbars, the main busbar and the auxiliary busbar. Each circuit is connected by a circuit breaker and two sets of isolating switches connected to the main busbar and the auxiliary busbar respectively. The reliability and flexibility are greatly improved, which is convenient for busbar maintenance;
2. The busbar chambers of the switch cabinet are independent of each other, which can effectively prevent the spread and spread of an accident in a busbar chamber;
3. An online intelligent temperature rise monitoring device can be installed to monitor the temperature rise of key parts of the main circuit in real time during normal operation;
4. It can realize a unitized structure with high transmission accuracy, simple installation, convenient adjustment and labor-saving operation;
5. The operation of the trolley can be carried out when the switch cabinet door is closed, and the circuit breaker emergency opening operation can also be carried out when the switch cabinet door is closed to ensure the safety protection of the operator in abnormal situations;
6. High-strength and large creepage distance support porcelain bottles and busbar hardware are used to effectively reduce busbar vibration and noise;
7. The shell protection level reaches IP3X.
