Description
Technical field
The invention belongs to field of tool, more particularly to a kind of operation spanner for being used to operate rotary shaft knife switch.
Background technology
Disconnecting switch (is commonly called as " disconnecting link " or " plug-in strip "), generally referred to as high voltage isolator, i.e. rated voltage in 1kV and
Disconnecting switch more than it, often referred to simply as disconnecting switch, are using a kind of most electrical equipment in high-voltage switch electric appliance；Due to making
Consumption is big, and functional reliability requires high, and the influence to electric substation, the design of power plant, foundation and safe operation is larger.Keep apart
What is closed is mainly characterized by no arc extinguishing ability, can only divide in the case of no load current, close circuit.It does not have cutout abilities,
Operated again after can only first circuit be disconnected with miscellaneous equipment.Disconnecting switch is widely used in power industry.
As power supply unit becomes increasingly popular on bar, on the bar with disconnecting switch guillotine type electrical control cubicles more and more by
Using, operate it is such be fixed on electric pole high-end guillotine type electrical control cubicles when, due to being, in high-altitude hanging operation, to be isolated
During " divide/close a floodgate " operation of switch, operating personnel is, in face of electrical control cubicles on bar, to immediate vicinity the operation of progress " face-to-face "
, so human users' force of operation is not very convenient on bar.
The reason for causing this situation is installing space and to be easy to guillotine type on execute-in-place, existing bar automatically controlled to save
The disconnecting switch of cabinet, without operation handle or operation button, only exposes electric control cabinet box surface about 8 to 10 on the surface of electrical control cubicles
Centimetre a section be square " point/close a floodgate " spin axis (being commonly called as square column), " point/close a floodgate " behaviour for carrying out disconnecting switch
Make, during due to using existing square hole spanner to be inserted in the square column of " divide/close a floodgate " spin axis, there are directional problems, be difficult accurate set
Enter, so relative difficulty in live operating process on the spot.
The square column of " divide/close a floodgate " spin axis is operated according to double offset ring spanner or adjustable wrench, although can preferably solve existing
" being inserted in " problem in the operation of field, but double offset ring spanner is not suitable for the site safety of operation on bar in the presence of an operation position asks
Topic, there is wrench opening degree using adjustable wrench needs to adjust on the spot, unhandy problem, and above two spanner there are
It is easy to come off from square column in practical operation, brings the actual danger factor of " falling object from high altitude ".
So-called high-rise working refers to the operation that eminence of the people on the basis of certain position is carried out.Standard GB/T/T3608-
2008《High-rise working is classified》Regulation：" it is all more than height of fall reference plane 2m (contain 2m) be possible to fall eminence is carried out
Operation, referred to as high-rise working." according to this regulation, power industry in be related to the scope of high-rise working be quite wide
General.
How the operating flexibility and reliability of in this case used operation spanner, direct relation are ensured
The work comfort degree and job security of operating personnel on to live bar.So, develop one kind and be exclusively used in electrical control cubicles on action bars
The operation spanner of knife switch, is of great practical significance.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of operation spanner for being used to operate rotary shaft knife switch.Its
Using polygonal-shaped openings structure, the head that integration operates spanner is sleeved in the operation rotating shaft of knife switch, passes through side
Exert a force the work pattern of operation, and reducing rotary shaft knife switch, operation spanner needs to rotate in " point/and lock " operating process every time
Angle, it is ensured that the operating flexibility and reliability of spanner, improve the work comfort degree of operating personnel on live bar, improve on bar
The job security of " divide/close a floodgate " operation.
The technical scheme is that：A kind of operation spanner for being used to operate rotary shaft knife switch, including spanner are provided
Bright and affixed with the bright one end of spanner driving end, it is characterized in that：
Described driving end is the laminated structure of flat；
One end of the driving end of the laminated structure with described hand is bright fixes as one；Being integrally formed rigid structure；
；In the middle part of described laminated structure, isolator operation axle jack is provided with；Described isolator operation axle is inserted
Kong Weiyi octagonal perforate.
Specifically, described octagonal perforate is polygon-octagonal perforate.
The described operation spanner for being used to operate rotary shaft knife switch, using polygon-octagonal perforate, to reduce rotary shaft
Operation spanner needs the angle rotated to knife switch in " point/and lock " operating process every time.
Further, the described operation spanner for being used to operate rotary shaft knife switch, the polygon-octagonal of driving end is opened
Borehole jack is in the operation rotating shaft of knife switch, to ensure the operating flexibility and reliability of spanner, improves and is operated on live bar
The work comfort degree of personnel, improves on bar the job security of " divide/close a floodgate " operation.
The described operation spanner for being used to operate rotary shaft knife switch, using the polygon-octagonal perforate of driving end, to subtract
The space of needs is operated when few rotary shaft knife switch " divides/closed a floodgate " operation on bar.
Further, described octagonal perforate is opened with importing property ramp edge so that driving end borehole jack enters plug-in strip
The operation rotating shaft of pass.
Compared with the prior art, it is an advantage of the invention that：
1. using polygonal-shaped openings structure, the driving end of spanner is operated to be sleeved on the operation rotating shaft of knife switch integration
On, the work pattern for the operation that exerted a force by side reduces rotary shaft knife switch and operated every time in " point/and lock " operating process
Spanner needs the operation when angle and the operation that rotate to need space；
2. the driving end that integration operates spanner is sleeved in the operation rotating shaft of knife switch, using positive the eight of driving end
