Description
Technical field
The present invention relates to a kind of high voltage isolator manufacture, maintenance field, particularly a kind of disconnecting switch back-moving spring is torn open
Discharging method.
Background technology
High voltage isolator is usage amount high-tension switch gear maximum, most widely used in power system.Due to high pressure
Disconnecting switch is installed, running environment condition is relatively more severe, operates among outdoor, by amblent air temperature in the case of having no to block
Impact is the most direct, and along with converting equipment in recent years by manual operation to electric operating, examined to state by periodic inspection system
The system of repairing, gradually extended to unattended progressively transition, the overhaul life of main equipment by Attended mode, thus by operating
The power outage that outdoor type disconnecting switch causes constantly occurs, and in continuous ascendant trend, the power supply directly affecting system can
By property and safety.Nowadays disconnecting switch defect gradually increases, and impact becomes larger, in order to ensure the reliable of disconnecting switch
Property, need disconnecting switch is carried out periodic inspection.
When dismantling the back-moving spring of conductive arm in GW16 type disconnecting switch, former method needs operated by two people.To keep apart
Pass contact stands upside down, and a people utilizes opening movable wrench or 2 iron core screwdrivers to be depressed by the pad of back-moving spring upper end, in exposing
Link pin, then pin is pounded out with hammer by another people, finally back-moving spring is taken out.
There are two problems in the method: 1, needs two people's operations, increases manpower, and needs two people's tacit agreements to coordinate；2, utilize
There is potential safety hazard in Manpower pad, owing to the elasticity of back-moving spring is compressed by interior link pin.When interior link pin is removed, bullet
Spring elasticity is released, if manpower does not notes or coordinates bad, pad is easily ejected by spring and hurts sb.'s feelings..
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of overhaul efficiency that improves, shorten inspection
Repair the time, reduce cost, accomplish the controlled disconnecting switch back-moving spring method for dismounting in control.
A kind of disconnecting switch back-moving spring method for dismounting, described method for dismounting uses removal tool special, and described tears open
The instrument of unloading includes the gusset plate that the transverse section of a section is L-shaped, and a U-shaped fixture, and fixing bolt, outside the one of L-type gusset plate
Be arranged at intervals with two location nuts on side, the screw direction of location nut along the length direction of gusset plate, location nut with
Fixing bolt is used in combination, and down, U-shaped open slot has the bottom of arc to the U-shaped open slot of U-shaped fixture, U-shaped solid
The top of locking member is provided with the hole passed for fixing bolt, during dismounting, the open slot of U-shaped fixture is inserted isolator operation
In bar, being inserted by gusset plate in disconnecting switch movable contact block gap, fixing bolt is through U-shaped fixture and gusset plate, solid by rotating
Determine bolt so that U-shaped iron plate is just stuck on the pad on disconnecting switch back-moving spring, then with the dynamic bolt of spanner lock, utilize spiral shell
Bolt characteristic, compression reseting spring, interior link pin is separated with pad, is finally pounded out with hammer.
Described removal tool special also includes two pads and locking nut, and two pads are respectively in U-shaped fixture
Front and back, locking nut is set between pad and gusset plate.
Before and after U-shaped fixture, side arranges pad, and arranges locking nut between gusset plate and a pad, so can carry
The degree of blocking of this disconnecting switch back-moving spring tool special for dismounting high.
It is provided with what the interior link pin for isolator operation bar strode across in the curved bottom both sides of U-shaped fastener openings groove
Groove.
Owing to the length of the interior link pin of isolator operation bar is consistent with the diameter length of pad, therefore arrange and be parallel to each other
2 grooves, recess width is slightly larger than the diameter of interior link pin, and the degree of depth should make the open slot of U-shaped fixture insert to keep apart
When closing action bars, groove strides across interior link pin just, and remainder is overlapped on pad, so after the dynamic bolt of lock, just can compress
Back-moving spring, separates pad with interior link pin.
In sum, the present invention following advantage compared to existing technology:
Manpower can be reduced after using disconnecting switch back-moving spring method for dismounting of the present invention, increase safety, improve greatly
Work efficiency, and have the advantage that
1. reduce the cost of overhaul.110kV collection rock I line 1432 disconnecting switch is become with electric company 220kV Jixian county, Guo Wang Longyan
As a example by, after using disconnecting switch Quick Release spring tool, only maintenance single-phase isolating switch can reduce the repair time about 20 minutes, whole group
Disconnecting switch can reduce the repair time 1 hour.Checking experiment efficiency is greatly improved, and the time cost of maintenance is reduced.
2. cost of manufacture is low.The material that this tool making is used be all commonly use, standing material: iron plate, bolt etc., and system
Make step simple.
3. improve job security, work efficiency.Use disconnecting switch Quick Release spring tool, in the mistake of dismounting back-moving spring
Cheng Zhong, it is not necessary to two people coordinate, only need one man operation, eliminate because of mismate, cause spring, pad to fly out, cause the person,
The probability of equipment damage, substantially increases job security and work efficiency.
4. economic benefit.With electric company 220kV Jixian county, Guo Wang Longyan become 110kV collection rock I line 1432 disconnecting switch into
Example, by integrate rock I line 143 interval load current as 170A, operation exists divide-shut brake bite phenomenon, upper conductive arm need to be entered
Row Disintegration overhaul, does not use the disconnecting switch Quick Release spring tool repair time to be about 5 hours, uses disconnecting switch Quick Release spring work
Can improve overhaul efficiency, only single-phase isolating switch after tool comprehensively and can reduce the repair time about 20 minutes, whole group of disconnecting switch can subtract
Few 1 hour repair time, reduce loss electricity √ 3 × 170 × 110 × 103 × 1=32388.4kwh, by average electricity price 0.5 yuan/
Kwh calculates, then reduce loss 1.620 ten thousand yuan.Guo Wang Longyan electric company cut-off in JIUYUE, 2013 totally 18 GW16 type disconnecting switch
Defect, can reduce the electricity charge and lose 29.16 ten thousand yuan.By the whole province 2012 totally 102 strip defect, then can reduce electricity charge loss up to
165.24 ten thousand yuan, the economic benefit of 165.24 ten thousand yuan can be created for electric power enterprise.If to 1211 groups of GW16 type isolation of the whole province
Switch carries out improvement overhaul, then can reduce electricity charge loss up to 1961.82 ten thousand yuan.
