Description
Technical field
The present invention relates to electricity fixer device, particularly relate to a kind of switch mechanism hotline maintenance vertical links holder.
Background technology
High voltage isolator is the indispensable equipment of transformer station, and maintainer is when overhauling converting station high voltage electrical apparatus, and disconnecting switch can provide one section of electrical separation, and forms one and be evident that cut-off point, in order to ensure the personal safety of maintainer.In view of disconnecting switch does not has special arc-control device, therefore it can not cut off load current or short circuit current, thus just can must carry out in the case of first cut-off breaker disconnecting switch point, closing operation, it is impossible to on-load draws disconnecting switch.
On the one hand, the reliability of operating mechanism case secondary control loop directly affects the reliability of disconnecting switch action, and auxiliary switch, travel switch switch loose contact not in place or contact and be all likely to result in disconnecting switch tripping, malfunction.Binding post loose contact, catalyst not adhesive, motor burn out, secondary line insulation breakdown etc. all can cause the malfunctioning of remote operation.Therefore, the secondary circuit of operating mechanism case and electric motor loop not only need reliably, and need durable and overhaul conveniently.
On the other hand, outdoor disconnector works owing to being directly exposed under atmospheric condition, is easily affected by natural environment and climate condition, and the fault of its operating mechanism is the most common failure of this kind equipment, as malfunctioning in mechanism's bite, auxiliary switch, short circuit that connecting line is aging etc. causes, short-term.High voltage isolator is during grid switching operation, and operating mechanism is malfunctioning, damages the phenomenons such as deformation the most often have generation including refusing point, refuse close a floodgate not in place and drive disk assembly of splitting or integrating.Adding up according to operating experience, the fault that disconnecting switch operating mechanism causes accounts for the 45% ~ 84% of disconnecting switch total failare, and after such fault occurs, traditional processing method needs to carry out the eliminating of fault under power down mode, has had a strong impact on the power supply reliability of system.
The mode of conventional process problem is: fills out with the first work ticket of transformer station, then carries out the eliminating of operating mechanism fault under the mode having a power failure.The advantage of this processing mode is: the maloperation of disconnecting link will not occur to divide by mistake, close, ensured the safety and stability of high pressure equipment.The shortcoming of this processing mode is simultaneously: carry out the eliminating of such fault under power failure mode, need to fulfil a series of formalities of power failure operation, it is the most difficult to process by bus disconnecting link, necessary I section of bus full cut-off electricity, large-area power-cuts is caused to have a strong impact on the power supply reliability of electrical network, averagely need to have a power failure 8 hours from the final elimination started to accident defect, have a strong impact on power supply reliability and the economic benefit of electrical network.
Summary of the invention
Need to carry out the deficiency in terms of the maintenance of operating mechanism fault and process in the way of power failure for disconnecting switch under tradition maintenance mode, the invention discloses a kind of switch mechanism hotline maintenance vertical links holder, by this invention so that maintenance and process outdoor disconnector mechanism-trouble time without conversion have disconnecting link point, "on" position, i.e. carry out getting rid of the process with defect, so that the power supply reliability of high-voltage fence and economic benefit are further improved by the fault that in the case of charged, operating mechanism case can be caused of quoting of this holder.
A kind of switch mechanism hotline maintenance vertical links holder that the present invention proposes, this holder comprises circular arc anchor ear, waling stripe, vertical links embrace folder, and circular arc anchor ear is connected with waling stripe, and waling stripe is embraced with vertical links to press from both sides and is connected；
Described circular arc anchor ear for carrying out the adjustment of degree of tightness when maintenance to holder, and circular arc anchor ear two ends possibly together with the bolt member adjusted for degree of tightness, are tightened or unclamped the bolt member at circular arc anchor ear two ends and can be adjusted holder upper and lower position；
Described waling stripe is used for connecting circular arc anchor ear and embraces folder with vertical links；
Described vertical links embraces clip pack containing 2 based on centrosymmetric connecting rod fixation clamp, 2 screw rods of the same size and supporting pad thereof and nut, and 1 insurance tip stop；
This holder using method is as follows, operating mechanism connecting rod is fastened by the nut embraced on 2 screw rods of folder by unclamping or fasten vertical links, when operating mechanism connecting rod and vertical links embrace folder be connected as a single entity and cannot loosen time, now nut is tightly dead, just think that connection puts in place, and in this case this insurance tip stop is fastened, a distant place now by mechanism case is electronic and manually all this disconnecting switch of actuating cannot carry out divide-shut brake switching on the spot, finally the rotation being connected with actuating connecting rod in operating mechanism case and transmission blocking device are disassembled and just complete the charged trouble shooting to switch mechanism case and issue handling under conditions of guarantee is safe and reliable.
Described waling stripe is that angle steel makes.
The invention have the advantages that, the present invention can reliably realize trouble shooting and the issue handling under conditions of charged to isolator operating mechanism case, through on-the-spot test repeatedly, this holder is completely suitable for the service work of 110kV and 220kV electric pressure transformer station, the problem avoiding the power supply reliability that power failure operation is brought, also improves the economic benefit of electrical network simultaneously.The present invention also have be simple to manufacture, the feature such as good, the low cost of ruggedness.
