Abstract
The utility model relates to a kind of 10 kilovolts of insulation nuclear phase hand carts, comprise the car body of bottom with wheel, car body both sides arrange vertical insulation barrier, car body top and bottom installing insulating baffle plate respectively, front insulation barrier is installed in the front end of car body, front insulation barrier is provided with three holes, and vehicle body installs two pieces of insulating barriers.The insulating space that formation one is three-dimensional in switch cubicle, not only avoids nuclear phase lever and the position short circuit of switch cubicle metal during nuclear phase, the short circuit caused between two nuclear phase levers because hand-held nuclear phase lever is unstable when it also avoid nuclear phase, realizes two people's safety operations.Substantially increase stability and the fail safe of operating efficiency and work.
Description
Technical field
The utility model belongs to electrical test technical field, and particularly a kind of 10 kilovolts of insulation nuclear phase hand carts, are applicable to 10 KV switch cabinet nuclear phases on-the-spot, reduce nuclear phase operating risk in 10 KV switch cabinets, improve nuclear phase operating efficiency in 10 KV switch cabinets.
Background technology
In 10 KV switch cabinets, nuclear phase is a live line working, carry out 10 KV switch cabinet kernel phase times, 10 kilovolts of switching on/off handcarts need be shaken out in switch cubicle, expose 10 kilovolts of fixed contacts, and after wheelbarrow switch shakes out, charged fixed contact is blocked by the two pieces of metal baffle up and down fallen, nuclear phase cannot be carried out, two pieces of baffle plates are chosen out by usual needs two people hand-held insulating bar respectively up and down, after exposing the charged fixed contact of three-phase, carry out nuclear phase work by the hand-held nuclear phase lever of testing crew.The switch cubicle domestic demand five people cooperation of about one meter completes nuclear phase work, narrow space operating difficulties simultaneously.Because fixed contact metal baffle need be chosen open with insulating bar, difficulty is comparatively large, distance 10 kv electriferous fixed contact close together, easily occurs baffle plate to be drawn and falls, and there is larger security risk.And because nuclear phase lever top is metal, the insulation of nuclear phase lever front end is lower, nuclear phase lever easily occurs over the ground or three-phase shortcircuit during nuclear phase.The safety of nuclear phase operation cannot be ensured.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of 10 kilovolts of insulation nuclear phase hand carts, solves the problem seeing 10 KV switch cabinet nuclear phase operating difficultiess.
Technical solutions of the utility model are as follows.
A kind of 10 kilovolts of insulation nuclear phase hand carts, comprise the car body of bottom with wheel, car body both sides arrange vertical insulation barrier, car body top and bottom installing insulating baffle plate respectively, front insulation barrier is installed in the front end of car body, and front insulation barrier is provided with three holes, and vehicle body installs two pieces of insulating barriers.
Described hole is set with insulating washer.
Described insulating barrier is slidably arranged in vehicle body.
Described vertical insulation barrier, insulation barrier and front insulation barrier form three-dimensional insulating space.
The utility model tool has the following advantages
1, by starting 10kV switch cubicle Internal baffle mechanical mechanism, pulled out by switching on/off handcart when successfully solving nuclear phase, baffle plate falls cannot the problem of nuclear phase.
2, by nuclear phase hand cart left and right sides, upper and lower sides, front end and the isolation of alternate employing insulating material, form the enclosure space of an insulation, because hand-held nuclear phase lever instability causes nuclear phase lever top ground and phase fault during success solution nuclear phase, greatly ensure that nuclear phase safety, realize two people's safety operations.
3, ensure that the person and the device security of this live line working of nuclear phase operation to greatest extent, guarantee that two people just can complete the nuclear phase work of 10kV switch cubicle, substantially increase stability and the fail safe of operating efficiency and work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, insulating barrier, 2, vertically insulation barrier, 3, car body, 4, wheel, 5, hole, 6, insulation barrier, 7, front insulation barrier.
Embodiment
Embodiment
As shown in Figure 1, a kind of 10 kilovolts of insulation nuclear phase hand carts, comprise the car body 3 of bottom with wheel 4, car body 3 both sides arrange vertical insulation barrier 2, car body top and bottom installing insulating baffle plate 6 respectively, front insulation barrier 7 is installed in the front end of car body, and vertical insulation barrier 2, insulation barrier 6 and front insulation barrier 7 form three-dimensional insulating space; Front insulation barrier is provided with three circular openings, 5, three circular openings 5 and is exposed by A, B, C three-phase fixed contact live end, and hole 5 is set with insulating washer, can carry out the diameter regulating hole, facilitate the fixed contact of different size to use according to fixed contact size; Vehicle body is slidably installed two pieces of insulating barriers 1, and A, B, the C tri-in car body separates by insulating barrier, and insulating barrier slides and arranges, and can carry out the space size that regulates each other, use flexibly according to concrete size.
During use, the nuclear phase hand cart being provided with insulation barrier is pushed in 10 KV switch cabinets, lower baffle plate on fixed contact is opened by the mechanical transmission mechanism of both sides, now, all isolated by insulating material inside switch cubicle surrounding, by No. 1 nuclear phase lever through insulating in the circular hole of handcart front end, the charged fixed contact of contact A phase, again No. 2 nuclear phase levers are passed in the circular hole of insulation handcart front end, the charged fixed contact of contact B phase, has insulating barrier to separate, avoids two nuclear phase lever tip contact between two-phase.Carry out nuclear phase work successively.
