Description

The substation secondary air switch little ground wire of enclosed type ground connection
Technical field
The present invention relates to a kind of substation secondary air switch little ground wire of enclosed type ground connection, be mainly used in change In power station, the secondary ground connection of the equipment such as change, voltage transformer is used at station.
Background technology
In the past in transformer station the secondary of the equipment such as station change, voltage transformer mainly use insurance to cut off therefore Barrier electric current, so the ground connection of secondary device mainly uses the little ground wire of crocodile clip, is fixed also by clip Screw in contact fuse terminals row reaches the purpose of reliable ground, thus prevents from setting when meeting substation equipment maintenance and repair The safety measure requirement of standby anti-power transmission.Along with air switch set at station change, voltage transformer etc. in recent years Standby is widely used, and Crocodile type earth lead has the disadvantage in that
1, carrying connecting groove due to air switch, the connecting groove of each producer is not of uniform size, the degree of depth differs; The clip that connecting groove bore is little cannot insert connecting groove, and the clip of depth as shallow cannot be fixed, and causing cannot be right Secondary device ground connection;It is accomplished by air switch is entered by expanding the method such as connecting groove bore, the increase degree of depth Row destroys or changes, and wastes time and energy expensive;Above-mentioned asking is there is also by changing the clip of Crocodile type earth lead Topic.
2, fix and reliable ground for convenience of Crocodile type earth lead, by naked for electric wire overlength during installation air switch Leakage, easily causes maintenance and operations staff touches by mistake, causes personnel's electric shock accidents.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide one knot Structure rationally, be capable of reliable ground, avoid air switch destroys and operates safe and reliable change The power station auxiliary air circuit breaker lock little ground wire of formula ground connection.
The substation secondary air switch little ground wire of enclosed type ground connection of the present invention, including base, spring Sheet, wiring pile, copper cash, earth clip and insulation sleeve, the side of base be provided with from top to down buckle and by The draw-in groove that two blocks are formed, the opposite side of base is fixed with wiring pile, and spring leaf is fixed on wiring pile, Being cased with insulation sleeve outside spring leaf, copper cash one end is fixed on base by wiring pile, and the other end connects Ground folder.
Operation principle and process:
During ground connection operation, first earth clip is clamped earthing pole, then the draw-in groove card formed by two blocks on base On the handle of air switch, buckle is stuck in the handle of air switch and the gap of shell simultaneously, connects And regulate the spring leaf with insulation sleeve, in spring leaf is inserted the connecting groove of air switch, make itself and wiring Bolt is fully contacted, and the operation of simple several steps just completes equipment reliable ground.
The shortcoming that the present invention is directed to Crocodile type earth lead, uses air switch enclosed type earth lead to instead of always The way of contact of formula earth lead, realizes by the way of using spring leaf ingress of air switch wire connection bolt Reliable ground, it is to avoid because expanding connecting groove bore, increasing the degree of depth air switch electric wire foreskin broken Bad problem, the mistake being simultaneously prevented from air switch is closed, it is achieved ground connection double insurance, makes site safety Measure is improved reliable.
The present invention is compared with prior art had the beneficial effect that
Present configuration is reasonable, can be light by the way of using spring leaf ingress of air switch wire connection bolt Pine installing secondary earth lead, and realize reliable ground, stop air switch is destroyed or changes product Raw waste time and energy expensive problem and personnel's electric shock accidents, has simultaneously and prevents air switch from closing function by mistake, It is grounded double insurance, makes site safety measure improve reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, spring leaf;2, insulation sleeve;3, base;4, wiring pile;5, copper cash;6, card Button;7, block;8, earth clip;9, handle;10, air switch;11, connecting groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
As it is shown in figure 1, this substation secondary air switch little ground wire of enclosed type ground connection, including base 3, bullet Reed 1, wiring pile 4, copper cash 5, earth clip 8 and insulation sleeve 2, the side of base 3 sets from top to down Being equipped with buckle 6 and the draw-in groove formed by two blocks 7, the opposite side of base 3 is fixed with wiring pile 4, spring Sheet 1 is fixed on wiring pile 4, and spring leaf 1 is outside is cased with insulation sleeve 2, and wiring pile is passed through in copper cash 5 one end 4 fix on the base 3, and the other end connects earth clip 8.
During ground connection operation, first earth clip 8 is clamped earthing pole, then two blocks 7 on base 3 are formed Draw-in groove is stuck on the handle 9 of air switch 10, and buckle 6 is stuck in the handle 9 of air switch 10 simultaneously With in the gap of shell, then regulate the spring leaf 1 with insulation sleeve 2, spring leaf 1 is inserted air and opens Making it be fully contacted with connection bolt in closing the connecting groove 11 of 10, the operation of simple several steps just completes equipment Reliable ground.
The shortcoming that the present invention is directed to Crocodile type earth lead, uses air switch enclosed type earth lead to instead of always The way of contact of formula earth lead, can be light by the way of using spring leaf ingress of air switch wire connection bolt Pine installing secondary earth lead, and realizes reliable ground, it is to avoid because expanding connecting groove bore, increase the degree of depth Problem air switch destroyed or change, time saving and energy saving, and effectively stopped personnel's electric shock accidents, Have simultaneously and prevent air switch from closing function by mistake, it is achieved ground connection double insurance, make site safety measure perfect Reliably.
