Abstract
The invention discloses a handcart switch bank-brake rail. The handcart switch back-brake rail is characterized by being composed of a cross bar, a left-end 'U'-shaped rail body, a right-end 'U'-shaped rail body and positioning plates, the left and right ends of the cross bar are respectively vertically fixed to the middle portion of the side wall of each of the left-end 'U'-shaped rail body and the right-end 'U'-shaped rail body in a welded manner, and the positioning plates are vertically fixed to the bottom wall of each of the left-end 'U'-shaped rail body and the right-end 'U'-shaped rail body in a welded manner, and the length of the cross bar is identical to the distance between moving rollers at two bottom ends of a handcart switch. The handcart switch can be pushed to the left-end 'U'-shaped rail body and the right-end 'U'-shaped rail body when the 10-kV switch and circuits are converted to back-braking maintenance from hot standby, moving operation is facilitated, operation time for the 10-kV handcart switch can be effectively shortened, and requirements of the maintenance department on trying to shorten blackout brake operation time is satisfactory; the handcart switch hand-brake rail is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of wheelbarrow switch grid switching operation accessory, specifically, in a kind of grid switching operation process that is mainly used in 10kV switch and line maintenance, can shorten the 10kV middle-placed switch cabinet grid switching operation time, improve the wheelbarrow switch back brake track of power supply reliability.
Background technology
Wheelbarrow switch is the main accessory in enclosed switchgear, in transformer station, power plant, industrial and mining enterprises, is used widely, corresponding with it, and circuit breaker cart grid switching operation also must increase.Wheelbarrow switch grid switching operation comprises conventional monitoring operation, one man operation, inspection operation.At present, when O&M operating personnel carry out 10kV switch and line maintenance operation task, at execution 10kV switch and circuit, by stand-by heat, turned in the grid switching operation process of maintenance, because two hooks before handcart are corresponding one by one in pushing handcart process, just can make handcart fix, this process need operating personnel are left and right adjustment handcart position constantly, disposable pushing in back brake mouth, so when adjusting handcart position, the operating time is longer, accounts for 60% of whole operating process.And the grid switching operation of 10kV wheelbarrow switch is directly connected to client and resident's electricity consumption situation, shortening the grid switching operation time is exactly the interruption duration that shortens client.Secondly, should overhaul department's requirement, in order to complete plant maintenance and the service work in transformer station on time, need O&M operating personnel to shorten the power failure grid switching operation time, for the valuable operating time is won in service work as far as possible.
Known by retrieving, have not yet to see by track and shorten the 10kV wheelbarrow switch report of grid switching operation time.
Summary of the invention
The object of the present invention is to provide a kind ofly by stand-by heat, to be turned in the grid switching operation process of maintenance carrying out 10kV switch and circuit, can effectively shorten the 10kV wheelbarrow switch operating time, and wheelbarrow switch back brake track simple in structure, easy to use.
In order to reach above object, the technical solution adopted in the present invention is: this wheelbarrow switch back brake track, it is characterized in that: it consists of cross bar, left end " U " shape track, right-hand member " U " shape track and location-plate, the left and right end of cross bar is fixed with the sidewall middle part vertical welding of left end " U " shape track, right-hand member " U " shape track respectively, at the fixing upper location-plate of the equal vertical welding of diapire of left end " U " shape track and right-hand member " U " shape track; The width of the width of the rail groove of described left end " U " shape track and right-hand member " U " shape track and wheelbarrow switch bottom shifting roller is adaptive, and the distance bottom the length of described cross bar and wheelbarrow switch between the shifting roller at two ends is consistent.
The present invention also implements by following measure: the rail groove diapire of described left end " U " shape track and right-hand member " U " shape track is provided with towards one end of wheelbarrow switch stretch out domatic.
The length of described left end " U " shape track and right-hand member " U " shape track is 140mm, is highly 36mm.
Beneficial effect of the present invention is: this wheelbarrow switch back brake track, due to when carrying out 10kV switch and circuit and turn maintenance grid switching operation by stand-by heat, wheelbarrow switch can be pushed on left end " U " shape track and right-hand member " U " shape track, be convenient to move operation, so can effectively shorten the 10kV wheelbarrow switch operating time, meet maintenance department about shorten the time requirement of power failure grid switching operation as far as possible, and simple in structure, easy to use.
