Abstract
The invention relates to a low-voltage isolation insulating cover which comprises two cover bodies symmetric with each other, fasteners and grooves. Each cover body is composed of three square insulating plates which are fixedly connected, wherein one of the square insulating plates is provided with two grooves parallel to each other. The fasteners penetrate through the grooves to enable the two cover bodies to be connected. The low-voltage isolation insulating cover has the advantages that the low-voltage isolation insulating cover is a tool which facilitates power distribution overhaul work, is of a detachable structure, is convenient to carry, guarantees that operation and maintenance workers avoid an electric shock safely, simplifies power outage steps, and improves power supply reliability.
Description
Technical field
The present invention relates to a kind of low pressure isolated insulation cover.
Background technology
In existing equipment, the power supply unit that generally puts into operation in the residential quarter is box-type substation and underground distribution station low-tension switch cabinet.When the low-voltage cable in the residential quarter broke down in recent years, in most cases the single loop fault was that low-voltage cable often occurs.When the O﹠M personnel overhaul, often run into the operation of low-voltage power supply system single supply interruption maintenance.But in the low-tension switch cabinet of operation, still there is charged nearby device.Generally, for the personal security that guarantees the O﹠M operation is avoided getting an electric shock, the processing that usually paripheral zone electric line equipment had a power failure has reduced the power supply reliability of low-voltage power supply system.Moreover, make and shorten the activity duration that has a power failure by too very complicated of power failure step before the operation and grid switching operation, affect greatly for the power failure operation.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this invention is to provide a kind of low pressure isolated insulation cover, can make things convenient for the instrument of distribution service work, guarantee the personal security of O﹠M operation, avoid getting an electric shock.
Realize above-mentioned purpose, the present invention is achieved through the following technical solutions:
A kind of low pressure isolated insulation cover, two cover bodies, securing member, the groove that comprise mutual symmetry, described cover body is composed of a fixed connection by three square insulation boards, and one of them square insulation board is provided with two grooves parallel to each other, and securing member passes groove two cover bodies are connected.
Described groove width is 20-30mm.
Described cover body is provided with handle.
Compared with prior art, the invention has the beneficial effects as follows:
This device is the instrument that can make things convenient for the distribution service work, for detachable structure, is easy to carry, and guarantees that the personal security of O﹠M operation is avoided getting an electric shock, and simplifies the power failure step, improves power supply reliability.

Fig. 1 is structural representation of the present invention (outside).
Fig. 2 is structural representation of the present invention (inside).
Among the figure: 1-cover body one 2-groove 3-securing member 4-handle 5-cover body two.
Embodiment
Below in conjunction with Figure of description the present invention is described in detail, but should be noted that enforcement of the present invention is not limited to following execution mode.
See Fig. 1, Fig. 2, a kind of low pressure isolated insulation cover, two cover bodies, securing member 3, the groove 2 that comprise mutual symmetry, described cover body is composed of a fixed connection by three square insulation boards, one of them square insulation board is provided with two grooves 2 parallel to each other, and securing member 3 passes groove 2 two cover bodies are connected.
Described groove 2 width are 20-30mm.
Described cover body is provided with handle 4.
Embodiment:
See Fig. 1, Fig. 2, with insulating material (for example: the resinae material) be compressed into the square insulation board that 3 length of sides are 1m, each adjacent both sides of square insulation board and two other square insulation board are mutually permanently connected, form cover body 1, also can form the cover body 1 of integral structure by compression.Open two grooves parallel to each other 2 near a square insulation board edge on the cover body 1, groove 2 width are 20-30mm.Making cover body 25 again makes itself and cover body 1 symmetrical, cover body 1 is formed the space that three side sealing closes with cover body 25, cover body 1 and cover body 25 are spliced, pass two grooves 2 that cover body is corresponding with the quarter butt screw, regulate the relative position of cover body 1 and cover body 25, determine the length in the space that three side sealing closes, fix by nut then; Described groove can be used to control the size of insulating cover.
Mounted insulating cover is docked inspection, check whether outward appearance exists outer thorn or contact position that the slit is arranged.Carry out the low pressure withstand voltage test simultaneously.
The present invention is demountable structure, has remedied when the O﹠M personnel carry out repair and maintenance to Switch equipment such as air switches the inconvenience that needs many families to have a power failure and bring, and provides powerful guarantee to distribution personnel's personal safety.
The cost cost is low, but has assembleability, has promoted the local replaceability of product, has prolonged life of product; Isolability greatly reduces the power failure operation to the user, has more protected operating personnel's life security, makes distribution serve high-quality more.Avoid emergency episodes such as electric shock, large-area power-cuts to take place timely and effectively, reduce the maintenance cost of switch cover.
