Description
Technical field
The invention belongs to disconnecting switch technical field of safety protection, and in particular to a kind of rain-proof type disconnecting switch protection dress
It puts.
Background technology
Disconnecting switch reliability requirement is high, is the critical facility in power transmission and transformation line, especially high voltage isolator, is to make
With a kind of most switch electric utilities, although although its principles and structure is simple, to electric substation, power plant sets
Meter and safe operation influence very big.Disconnecting switch is mainly used to that the part having a power failure will be needed reliably to isolate in high voltage distribution installation,
To ensure the safety of service work.Disconnecting switch does not have arc-control device, it is impossible to load current or short circuit current flow are cut off, it can only be in nothing
Divide in the case of load, close circuit.Disconnecting switch is used for each step voltage, is disconnected as circuit connection or equipment is changed with power supply,
It can only again be operated without cutout abilities after with other equipment, circuit is disconnected.
Outdoor high voltage isolator is in the adverse circumstances such as wind and rain, ice and snow, filth, condensation, frost, so its common event
Barrier has contact portion overheat, contact resistance increase, can cause electric arc, burn contact etc. during drawing.
The content of the invention
A kind of rain-proof type disconnecting switch protective device, the dress are provided the purpose of the present invention is overcome the deficiencies in the prior art
The service life of outdoor high-voltage isolating switch can not only be extended by putting, and can eliminate outdoor high-voltage isolating switch normal use
When security risk, novel in structural design is practical and convenient.
In order to achieve the above object, the present invention adopts the following technical scheme that：
The present invention provides a kind of rain-proof type disconnecting switch protective devices, it includes bottom plate and protective cover, and the center of bottom plate opens up
There is the opening through disconnecting switch, leakage hole is offered on the surrounding side wall of bottom plate；The protective cover is by bottomless cuboid
Box body and edge composition, the outside of four side wall bottoms of cuboid box body are equipped with outwardly extending edge, and edge is equipped with solid
Determine hole, protective cover is by passing through the fixing bolt in mounting hole to be fixed on bottom plate；On the front-rear side walls of the cuboid box body
Through hole is offered, the center line of two through holes coincides, and the inside of through hole is equipped with protection pipe, and fixation is arranged in protection pipe
Set.
According to above-mentioned rain-proof type disconnecting switch protective device, the contact site of the protective cover and bottom plate is equipped with anti-watertight
Packing.
According to above-mentioned rain-proof type disconnecting switch protective device, slot is offered at the top of the cuboid box body,
The upper surface of slot is equipped with the draw back plate that can be covered and close slot.
Compared with prior art, the advantageous effect that the present invention obtains：
1. structure of the present invention includes bottom plate and protective cover, the center of bottom plate offers the opening through disconnecting switch, the four of bottom plate
Leakage hole is offered on all side walls；The protective cover is made of bottomless cuboid box body and edge, and the four of cuboid box body
The outside of a side wall bottom is equipped with outwardly extending edge, and edge is equipped with mounting hole, and protective cover is by passing through in mounting hole
Fixing bolt is fixed on bottom plate；Through hole, the center line of two through holes are offered on the front-rear side walls of the cuboid box body
It coincides, the inside of through hole is equipped with protection pipe, and fixing sleeve is arranged in protection pipe；Edge is used to consolidate protective cover in the structure
It is scheduled on bottom plate, for protection pipe for protecting the electric wire pulled out from disconnecting switch, fixing sleeve is rectangular for protection pipe to be fixed on
On body box body；Leakage hole is offered on the surrounding side wall of the structure bottom plate, the design of leakage hole effectively can prevent rainwater from entering
Protective case.
2. the contact site of protective cover of the present invention and bottom plate is equipped with waterproof sealing gasket, waterproof sealing gasket is used to increase
Sealing performance；Slot is offered at the top of the cuboid box body, the upper surface of slot, which is equipped with, can cover conjunction rectangle

Description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the structure diagram of bottom plate of the present invention；
Fig. 3 is the structure diagram of protective cover of the present invention.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
It please refers to Fig.1 shown in ~ 3, a kind of rain-proof type disconnecting switch protective device, it includes bottom plate 1 and protective cover 2, bottom plate 1
Center offer opening 3 through disconnecting switch, offer leakage hole 4 on the surrounding side wall of bottom plate 1；The protective cover 2 is
It is made of bottomless cuboid box body 21 and edge 22, the outside of four side wall bottoms of cuboid box body 21, which is equipped with, to extend outwardly
Edge 22, edge 22 be equipped with mounting hole 23, protective cover 2 by the way that the fixing bolt in mounting hole is passed through to be fixed on bottom plate,
Protective cover 2 and the contact site of bottom plate 1 are equipped with waterproof sealing gasket 5；It is offered on the front-rear side walls of the cuboid box body 21
Through hole 6, the center line of two through holes 6 coincide, and the inside of through hole 6 is equipped with protection pipe 7, and fixing sleeve is arranged in protection pipe 7
8。
