Abstract
The utility model provides an exclusive formula high tension switchgear that prolongs of generating line, including the high -voltage board cabinet body, the high pressure is female to be arranged outside lateral wall through the high -voltage board cabinet body extends to, sets up and be equipped with the high -voltage board insulator on female the arranging of high pressure of the internal portion of high -voltage board cabinet, extends to that outer high pressure is female arranges accessible earth connection or earthing knife -switch ground connection. The beneficial effects of the utility model are that its additional equipment of high tension switchgear can directly identify electroless back ground connection when overhauing, effectively the conservation work personnel avoid the injury of electrocuteeing, and factor of safety is high.
Description
Technical field
This utility model belongs to electrical equipment technical field, especially relates to a kind of bus bar extensional mode high-tension switch cabinet.
Background technology
Transformer substation high voltage chamber inside enclosed high-tension switch cabinet (10-35kV), the equipment of bus bar and connection thereof is enclosed in cabinet.
When interruption maintenance, needing reliable ground at possible for repair apparatus incoming call, protection staff avoids injury of getting an electric shock.Will
Before repair apparatus ground connection, need to check this equipment to have a power failure just and can pass through grounding switch or ground connection, due to mother
Line row is arranged in the high-voltage board of closing, it is impossible to directly electrical verification, if charged co-grounding switch, can damage associate power equipment,
A kind of high-tension switch cabinet that can solve this problem needs to research and develop further.
Utility model content
The bus bar extensional mode that the purpose of this utility model is to provide a kind of simple in construction, simple to operate, safety coefficient is high is high
Compress switch cabinet.
The technical solution of the utility model is: a kind of bus bar extensional mode high-tension switch cabinet of the present utility model, including high pressure
Cabinet cabinet, outside high-voltage busbar is extended to by the sidewall of high-voltage board cabinet, is arranged on the high-voltage busbar in portion in high-voltage cabinet body
It is provided with high-voltage board insulator, extends to outer high-voltage busbar and can pass through earth lead or grounding switch ground connection.
Preferably, extending to outer high-voltage busbar and be provided with high-voltage earthing ring, high-voltage earthing ring passes through high-voltage earthing lead-out wire
Connect high-voltage connecting place.
Preferably, described high-voltage busbar extends paramount by being arranged on the wall bushing on the sidewall of high-voltage board cabinet or hole, side
The outside of pressure cabinet cabinet.
Preferably, extend to outer high-voltage busbar and be arranged on grounding box box house.
Preferably, the bottom of described grounding box casing is provided with grounding box Xiamen, and grounding box hinge is passed through in described grounding box Xiamen
It is hinged on grounding box casing.
Preferably, the sidewall of described grounding box casing is provided with grounding box door-plate, and described grounding box door-plate is provided with padlock lock
Nose and grounding box handle lock.
This utility model has the advantage that with good effect:
1, owing to using technique scheme, high-tension switch cabinet is more time saving and energy saving when electrical verification, ground connection, is not switched on closing
High-voltage board i.e. cocoa directly carries out electrical verification, effectively protects the safety of staff and equipment, and stability is high.
