Abstract
The invention discloses a pushing device for a fixed contact seal plate mechanism of a centrally installed switchgear. The pushing device comprises an I-shaped frame which comprises two parallel cross bars and a connection rod mounted between the two cross bars, wherein the connection rod adopts a width adjustment structure; each cross bar is provided with one insulating bar, and the other ends of the two insulating bars are mutually connected and are connected with a hand push rod located at the rear end of the I-shaped frame in the forward moving direction; a groove block is further arranged at the front end of each cross rod, and rabbets of the groove blocks face outwards and are used for pushing an opening part of the seal plate mechanism. The pushing device for the fixed contact seal plate mechanism of the centrally installed switchgear simulates a base of a handcart switch; when the fixed contact seal plate mechanism of the centrally installed switchgear is inspected, the device is pushed into a guide rail to push the seal plate mechanism, then faults of the electrified seal plate mechanism can be visually revealed, fault points are determined, the maintenance efficiency is effectively improved, and meanwhile, the whole device is simple in structure and economical due to the fact that a material cost is low.
Description
Technical field
The present invention relates to a kind of middle-placed switch cabinet fixed contact shrouding mechanism urges device, belong to electrical equipment technical field.
Background technology
In 10kV switch cubicle type, middle-placed switch cabinet is modal a kind of form.Its common primary fault can be divided into wheelbarrow switch partial fault and cabinet partial fault substantially.Wheelbarrow switch fault mainly contains the problems such as circuit breaker tripping, circuit breaker malfunction, energy storage, can check all parts on wheelbarrow switch, failure cause being found out and eliminating by wheelbarrow switch being changed maintenance; Cabinet partial fault is stuck primarily of wheelbarrow switch inlet/outlet mechanism, fixed contact shrouding cannot the normal problem such as open closed, switch chassis locking fault, when running into cabinet itself and having fault, because effectively cannot observe whole mechanism when bus is charged and wheelbarrow switch passes in and out cabinet, when carrying out defect elimination to middle-placed switch cabinet switch cabinet fault, be difficult to judge its failure cause directly and accurately, can not suit the remedy to the case, thus interruption duration will be increased to a great extent.
At present, there is following problem in maintenance in middle-placed switch cabinet cabinet, test:
1, when the action of fixed contact shrouding is not in place, the position of mechanism's bite can not effectively be observed;
2, when wheelbarrow switch turnover switch cubicle, if block, cannot direct failure judgement position;
3, existing middle-placed switch cabinet phasing tester, must shake wheelbarrow switch to service position, just in case switch malfunction, easily causes accident;
4, when carrying out monospace switch commissioning test at ordinary times, because bus is charged, have no idea to check Gui Nei mechanism and fixed contact.
In view of this, the present inventor studies this, and develop a kind of middle-placed switch cabinet fixed contact shrouding mechanism urges device specially, this case produces thus.
Summary of the invention
The object of this invention is to provide a kind of middle-placed switch cabinet fixed contact shrouding mechanism urges device, can promote shrouding mechanism, and then intuitively represent the fault of charged middle shrouding mechanism, clear failure point, effectively improves overhaul efficiency.
To achieve these goals, solution of the present invention is:
A kind of middle-placed switch cabinet fixed contact shrouding mechanism urges device, comprise cap ned, described cap ned comprises two cross bars be parallel to each other, and the connecting rod be arranged between two cross bars, described connecting rod is width-adjustable joint structure, and two cross bars are equipped with an insulating rod, and the other end of 2 insulating rods is interconnected, and be connected with a handspike, described handspike is positioned at the rear end of line direction before cap ned; The front end of described cross bar is provided with a groove block further, and the notch of groove block outwardly, is used for promoting the opening feature of shrouding mechanism.
As preferably, described connecting rod comprises a female bar, and the sub bar be set on female bar, female bar is provided with an adjusting nut further, by the cooperation of female bar and sub bar, can regulate arbitrarily the length of connecting rod, then be tightened by adjusting nut fixing, the spacing of spacing and middle-placed switch cabinet two guide rails of two cross bars is consistent.
As preferably, described insulating rod is arranged on the middle part of cross bar, is convenient to cap ned to push shrouding mechanism.
As preferably, described groove block is for being obliquely installed, and the spacing of two relative groove block front ends is greater than the spacing of rear end, arranges like this and can more easily enter shrouding mechanism.
The base of middle-placed switch cabinet fixed contact shrouding mechanism urges unit simulation wheelbarrow switch of the present invention, underway put cabinet static contact shrouding mechanism check time, this device is pushed guide rail, promote shrouding mechanism, and then intuitively can represent the fault of charged middle shrouding mechanism, clear failure point, effectively improve overhaul efficiency, and whole apparatus structure is succinct, the cost of material is low, economical and practical.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the middle-placed switch cabinet fixed contact shrouding mechanism urges device stereogram of the present embodiment;
Fig. 2 is the middle-placed switch cabinet fixed contact shrouding mechanism urges device vertical view of the present embodiment.
Embodiment
As shown in Figure 1-2, a kind of middle-placed switch cabinet fixed contact shrouding mechanism urges device, comprise cap ned, described cap ned comprises two cross bars be parallel to each other 1, and the connecting rod be arranged between two cross bars 1, described connecting rod comprises a female bar 2, and the sub bar 3 be set on female bar 2, female bar 2 is provided with an adjusting nut 4 further, by the cooperation of female bar 2 and sub bar 3, the length of connecting rod can be regulated arbitrarily, then tighten fixing by adjusting nut 4, in use, article two, cross bar 1 coordinates to be placed on two guide rails of middle-placed switch cabinet, therefore the spacing of two cross bars 1 must be consistent with the spacing of middle-placed switch cabinet two guide rails, adopt telescopic connecting rod, can by middle-placed switch cabinet fixed contact shrouding mechanism urges application of installation in the middle-placed switch cabinet of plurality of specifications.
Article two, other end cross bar 1 being equipped with an insulating rod 5,2 insulating rods 5 is interconnected, and is connected with a handspike 6, and described handspike 6 is positioned at the rear end of line direction before cap ned; Handspike 6 the distance that can increase people and shrouding mechanism is set, ensure safety.Described insulating rod 6 is arranged on the middle part of cross bar 1, and described handspike 6 is parallel with cross bar 1, and is positioned at the middle of 2 cross bars 1, arranges like this, and cap ned is accurately pushed shrouding mechanism by the power be convenient to economizing most.
The front end of described cross bar 1 is provided with a groove block 7 further, and the notch of groove block 7 outwardly, is used for promoting the opening feature of shrouding mechanism, described groove, 7 for being obliquely installed, and the spacing of two relative groove block 7 front ends is greater than the spacing of rear end, arranges like this and can more easily enter shrouding mechanism.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present invention.
