Description
Technical field
The invention belongs to electric auxiliary facility, it is mainly used in power supply field.
Background technology
The open type 35kV handcart type breakers used now, its structure are：Top static contact is connected with bus, and lower section is quiet
Contact is connected with electrical equipments such as cables, and centre uses portable handcart circuit breaker.During power failure operation, breaker is disconnected, hand
Car is pulled to testing position, dynamic/static contact separation.Due to upper and lower 0.7 meter of contact distance, and upper contact head is connected with bus, it is difficult to is stopped
Electricity, need to be overhauled at lower contact again, the operation such as cable testing, staff can not ensure in operation process with it is powered
The part moment keeps enough safe distances, the danger that operation behaviour causes to get an electric shock be present.
The content of the invention
After solving the pull-out of 35kV open types wheelbarrow switch, upper contact head is powered, maintenance, institute's connecting cable at lower contact
During the operations such as experiment, the problem of can not ensureing to keep safe distance with the live part moment, the present invention provides a kind of movable type and connect
Ground experimental rig and its test for ground method, it is ensured that keep safe distance with electrical body in construction operation, realize that cable can be abutted against
The convenient function of ground, test connection.
Ensure to complete staff in construction operation, safe distance is kept with the electrical body moment.And it can realize that cable needs
When being grounded, it is not necessary to it is interim that ground wire is set, realize reliable ground.During for cable testing, it can be connected on this handcart, also protect
The safety of testing crew is demonstrate,proved, test connection is convenient.To preventing accident of human electric shock, remarkable benefit.
