Description
Technical field
The present invention relates to a kind of switch cubicle multifunctional electricity-detection car.
Background technology
For 40.5kV switch cubicle, in 40.5kV clad withdrawal-type AC metal-enclosed switch cabinet, when scene needs to overhaul switch cubicle, the requirement specified by safety operation must carry out electrical verification operation to the bus in switch cubicle or cable side, confirms can carry out ground connection without after electricity.Because the main bus bar of this type of 40.5kV armored withdraw type closed switch cabinet is completely enclosed within switch cubicle, if will carry out direct electrical verification first kind of way is that proofer uses unlocking tool to open cabinet door, after removing shrouding, adopt the direct electrical verification of electroscope.The second way extracts handcart in cabinet out, and proofer opens in cabinet and carries out electrical verification with electroscope to fixed contact after valve baffle plate.
All there is certain insecurity to proofer in above two kinds of direct electrical verification modes.
Summary of the invention
The object of this invention is to provide a kind of switch cubicle multifunctional electricity-detection car of easy to use, handling safety, each phase main bus bar side in switch cubicle can be checked out accurately whether charged.
A kind of switch cubicle multifunctional electricity-detection car, its special feature is: comprise vehicle frame, in the bottom of this vehicle frame, wheel is installed, driving shaft is respectively equipped with in the two bottom sides of this vehicle frame, and three high pressure sensors are installed on the top of vehicle frame, the top of each high pressure sensor is all provided with a contact arm, and be all provided with a supporting Mume flower contact on the top of each contact arm, the secondary connection end of each high pressure sensor is all electrically connected with Intelligent live display unit in addition.
Wherein charged display device comprises display module and voice alarm module, and this charged display device is detachably arranged on vehicle frame.
The invention has the beneficial effects as follows: 1, the body frame structure for automotive of switch cubicle multifunctional electricity-detection car of the present invention is simple, low cost of manufacture, and install, easy to use; 2, switch cubicle multifunctional electricity-detection car is adopted to carry out electrical verification to main bus bar side in switch cubicle convenient, to use with other function handcarts (as vacuum circuit-breaker handcart, voltage mutual inducer trolley, isolation handcart etc.) with the high-tension switch cabinet of existing 40.5kV electric pressure and mode of operation completely the same, application is simple, and fail safe is high and have the function of electrical verification, nuclear phase, voice safety instruction and LED display; 3, switch cubicle multifunctional electricity-detection car makes electrical verification efficiency improve on the basis that fail safe improves.

Accompanying drawing 1 is multifunctional electricity-detection car owner view of the present invention;
Accompanying drawing 2 is multifunctional electricity-detection car left view of the present invention;
Accompanying drawing 3 is multifunctional electricity-detection axletree mapping of the present invention.
Embodiment
As shown in Figure 1, 2, 3, the invention provides a kind of switch cubicle multifunctional electricity-detection car, comprise vehicle frame 1, in the bottom of this vehicle frame 1, wheel is installed, driving shaft 6 is respectively equipped with in the two bottom sides of this vehicle frame 1, and three high pressure sensors 3 are installed on the top of vehicle frame 1, the top of each high pressure sensor 3 is all provided with a contact arm 4, all be provided with a supporting Mume flower contact 5 on the top of each contact arm 4, the secondary connection end of each high pressure sensor 3 is all electrically connected with Intelligent live display unit 2 in addition.
Wherein charged display device 2 comprises display module and voice alarm module, and this charged display device 2 is detachably arranged on vehicle frame 1.
Embodiment 1:
For 40.5kV switch cubicle multifunctional electricity-detection car:
As shown in Figure 1, 2, 3,40.5kV switch cubicle multifunctional electricity-detection car comprises vehicle frame 1, Intelligent live display unit 2, A phase high pressure sensor 3, B phase high pressure sensor 31, C phase high pressure sensor 32, A phase contact arm 4, B phase contact arm 41, C phase contact arm 42, A phase Mume flower contact 5, B phase Mume flower contact 51, C phase Mume flower contact 52;
Wherein in the bottom of this vehicle frame 1, wheel is installed, both sides bottom this vehicle frame 1 are respectively equipped with driving shaft 6, and A phase high pressure sensor 3 is also installed on the top of vehicle frame 1, B phase high pressure sensor 31, C phase high pressure sensor 32, with A phase contact arm 4, B phase contact arm 41, C phase contact arm 42, and A phase Mume flower contact 5, B phase Mume flower contact 51, C phase Mume flower contact 52, A phase high pressure sensor 3 in addition, B phase high pressure sensor 31, the secondary connection end of C phase high pressure sensor 32 is also electrically connected with Intelligent live display unit 2, Intelligent live display unit 2 is arranged on electricity detection vehicle panel 7, can by manual observation and control, obtain display and the sound result of electrical verification and nuclear phase.
During use, when electricity detection vehicle pushes in switch cubicle, driving shaft 6 and the effect of switch cabinet shutter connecting rod of vehicle frame 1 left and right sides, switch cabinet shutter is opened, thus make A phase Mume flower contact 5, B phase Mume flower contact 51, C phase Mume flower contact 52 engages to the corresponding fixed contact in switch cubicle, thus the high-tension electricity on the conductor be connected with fixed contact is passed through Mume flower contact, contact arm causes high pressure sensor, and then by high pressure sensor, high-voltage variable is changed to low-voltage, Intelligent live display unit 2 is exported to by the secondary wiring terminals of high pressure sensor, nuclear phase and electroscope function will be realized simultaneously, the voice key pressed in Intelligent live display unit 2 synchronously will realize acousto-optic voice alarm, electrical verification, nuclear phase function.
