【KYN1-10 High Voltage Switchgear 】 

  
KYN-10 AC metal armor is running away switchgear 10KV high voltage switchgear in the power system, is small, interchangeable easy maintenance, complete performance, the reliability, security and reliability features. The technical performance standard GB3906-91 "3 ~ 35kv AC metal-enclosed switchgear." Rated insulation level consistent with GB311.1-97 "insulation with high voltage transmission and distribution equipment", rated frequency is 50Hz, rated current rating: 630A, 1000A, 1250A, 2000A, 3000A, the temperature jump GB763 "exchange of high-voltage electrical appliances in long-term work of the heat "; points, closing units and auxiliary circuit rated voltage, DC to 48,110,220 V; exchange for the 100,220,380 V.

The switchgear ratings and the same structure for all in need of replacement components to swap. Isolation and earthing switch contacts meet GB1985-89 provides that the fracture is visible isolation, contact isolation or grounding switch position shown by a reliable indicator. Used to install tubular metal in the ground electric heaters to prevent condensation when the device out of operation. The switch cabinet and the functional unit of each system, where the required ground with highly reliable grounding device, and to ensure the continuity of grounding system. In order to eliminate internal fault, also considered sufficient insulation distance, to avoid the emergence within the arc, and to take a reliable interlock to prevent misuse of the device, set up direct signal devices; additional space in the pressure release channel circuit breaker to reduce the gap over-voltage phenomenon .

Switch cabinet housing, welded with steel plate and angle steel, the former board and use bolts to connect after the cabinet, the relay control box and the cabinet with shock absorber connection. Switch cabinet with overhead inlet and outlet, out cable, so contact the feature.

Switchgear reliable interlock device.

1, only the switch is in the sub-gate position, the handcart can pull out and promote.

2, only when the isolation contact in the off position, the grounding switch to operate.

3, in addition to switches without auxiliary circuit which can automatically switch on the case, if no auxiliary circuit connected, in working position switch not closing. Secondary work location does not allow free plug.

4 Used in the work place or work location and test location between, the grounding switch can not be connected, grounding switch is turned parts can not be removed from the ground into the work position or location of test location.

5, the back door and ground operations with the chain axis, locking devices to prevent the operator being diverted to a power interval.
