Description
Technical field
The present invention relates to overhaul of line breaker technical field, especially relate to a kind of chopper dismounting plum blossom contact device.
Background technology
Chopper is the electric control appliance that power plant, electric substation are main, has arc quenching characteristic, when system is properly functioning
Time, it can be switched off and on circuit and the zero load of various electrical equipment and load current；When system jam, it and continue
Electric protection coordinates, and energy disengagement failure electric current rapidly, to prevent expansion accident scope.Therefore, the quality of chopper work, direct shadow
Ring the safe operation to power system.No matter power circuit is in any state, and such as unloaded, load or short trouble, when wanting
When seeking breaker actuation, it can reliably action, close or cut off circuit.Chopper can cut-off, closes and cut-off regulation
Abnormal current, such as overcurrent and short circuit current.Chopper plays a part three aspects in electrical network: first, according to electrical network
Running and need, chopper has control action, and chopper puts into some electrical power equipment or circuit or out of service；Second, disconnected
Faulty component is quickly excised from electrical network by road device when power circuit or device fails, it is ensured that the no failure part in electrical network
Properly functioning, there is protective effect；3rd, repair apparatus or the equipment of installation can be isolated by chopper with high voltage power supply, have peace
Full buffer action, it is ensured that maintenance installation personnel and the safety of equipment.
Just because of chopper carries the most important effect in power system, and electrical network electricity consumption load too high causes
May there is fever phenomenon because of loose contact in the Mume flower contact of chopper, as processed not in time, it will causes chopper
Mume flower contact Spring pinch force persistently reduce, and then the dynamic/static contact contact resistance on chopper can be made constantly to increase, enter
One step can cause the Mume flower contact heating scaling loss of chopper, even can explode.Therefore, the Mume flower contact of chopper is carried out
Overhaul timely and change the important guarantee being to ensure that safe operation of power system.
But when the Mume flower contact of chopper is overhauled or changes, traditional method be still that use screwdriver,
Conventional service kit dismounting contact and the adnexaes thereof such as glue pincers, there is many shortcomings in this maintenance replacing options, mainly has
Article three: first, owing to there being four fastening springs on the Mume flower contact of chopper so that in disassembly process, one man operation's difficulty is relatively
Greatly, two maintainers are at least needed to match；Second, tight due to require between Mume flower contact and the fastening spring of chopper
Property higher so that dismounting is time-consumingly the longest；3rd, in the Mume flower contact Renewal process of chopper, fastening spring need to be pried open, this
Sample easily causes the parts such as Mume flower contact fastening spring, fingertip and the conductive arm of chopper and displacement occurs, deforms or damage etc. is existing
As so that power equipment is in operation and there is certain potential safety hazard.
Therefore, design a kind of simple and compact for structure, easy to operate and can carry out operating in small space disconnected
Road device dismounting plum blossom contact device, is bound to be favored by market.And chopper Mume flower contact can be increased substantially
Maintenance and replacing efficiency, saved the cost of overhaul while improving Operation of Electric Systems safety.
Number of patent application 201220580066.9 discloses a kind of high pressure cabinet handcart contact of breaker installation tool, including holding
Holding handle and extension bar, described extension bar one end is provided with interior six square toes, and the described extension bar other end welds with described gripping handle
It is connected together, between described gripping handle and extension bar, is provided with knighthead；Described knighthead is two, is distributed position
In extension bar both sides, symmetrically.This utility model is applicable to the bolt within fastening high cabinet contact conductive arm and contact box,
By the knighthead arranged between extension bar and handle, make installation tool firmer, it is to avoid using for a long time
Journey causes damage, it is possible to effectively reduce job costs, improve work efficiency, and facilitate durable, last a long time.But,
This utility model volume is relatively big and is not suitable for the dismounting of chopper Mume flower contact.
It is special that number of patent application 201520821181.4 discloses a kind of indoor high-voltage vacuum circuit breaker Mume flower contact assembling
Instrument, including cylindrical bar and conical rod, described cylindrical bar is fixedly connected on the miner diameter end of described conical rod, described conical rod big
Footpath end is provided with socket cap, and the axis of described cylindrical bar, described conical rod and described socket cap overlaps.This utility model is at dress
When joining Mume flower contact, the used time is comparatively short, has saved human resources, will not damage the silver coating on element and element, it is ensured that assembling
Quality.But, this utility model needs this instrument by other instruments from prunus mume (sieb.) sieb.et zucc. after the assembling completing chopper Mume flower contact
Pull down on flower contact, and be not suitable for the dismounting of on-the-spot chopper Mume flower contact.
Summary of the invention
In view of this, it is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of chopper dismounting plum blossom contact
Device, has simple and compact for structure, easy to operate and that the suitability is wide advantage, it is only necessary to single can be in small space
Operate, it is possible to increase substantially the maintenance of chopper Mume flower contact and change efficiency, improving Operation of Electric Systems safety
While saved the cost of overhaul.
