Abstract
An operation safety guard device for a disconnecting switch is characterized in that the safety guard device comprises two supports, each support is formed by connecting two transverse square tubes and two longitudinal square tubes in a fastening mode, the two transverse square tubes of each support are respectively provided with a hoop used for being fixed to a cement rod below the disconnecting switch, the two longitudinal square tubes of each support are respectively hinged to an insulating guardrail through a hinge, and the two opposite insulating guardrails on the two supports are connected through a plug pin. With the operation safety guard device for the disconnecting switch, workers can be protected in an annular mode while movement space for normal operation is provided for the workers, operation safety of the workers at a transformer substation is guaranteed, electric shock injuries and deaths and other power grid accidents are avoided for personnel, and the operation safety guard device for the disconnecting switch is simple in structure and convenient to assemble and disassemble.
Description
Technical field
The present invention relates to substation safety protector, a kind of isolator operation safety device particularly, is particularly useful for the grid switching operation of GW5A-66 type isolating switch.
Background technology
When operation GW5A-66 type isolating switch, there is accident risk in the staff of transformer station, reason is, there is the porcelain knob risk of fracture suddenly in GW5A-66 type isolating switch, post-rift porcelain knob 9(is shown in Fig. 6) natural downslide under Action of Gravity Field, and live wire swings naturally, easily touch the staff of its below, during staff is flurried, runs and cause step voltage electrification injures and deaths, or directly touch 66 kv electriferous wires, the personnel that the cause injures and deaths of getting an electric shock cause electrical network (system earth, electric discharge etc.) accident simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly guarantees the staff of transformer station handling safety, avoids the get an electric shock isolator operation safety device of injures and deaths and power grid accident of personnel, and it is simple in structure, assembling and convenient disassembly.
Technical scheme of the present invention is:
A kind of isolator operation safety device, its special character is: comprise two supports, described support is fastenedly connected and is formed by two horizontal square tubes and two vertical square tubes, in two horizontal square tubes, be respectively equipped with the anchor ear being fixed together for the cement pole with isolating switch below, two vertical square tubes of described support are utilized respectively the hinged insulated guardrail of folding, and on two stands, two relative insulated guardrails utilize latch to connect.
Above-mentioned isolator operation safety guide rail, described insulated guardrail is provided with socket, and described socket is provided with stopper slot, so that coordinate and realize being connected with separated insulated guardrail with latch.
Described insulated guardrail is grid structure.
The invention has the beneficial effects as follows:
During staff's disconnecting switch operation, two stands utilizes the cement pole of anchor ear and isolating switch below to be fixed together, launch insulated guardrail and utilize latch to connect the insulated guardrail of two stands respective side, it offers the activity space of staff's normal operating, the ring protection of formation to staff, once isolating switch porcelain knob occurs to rupture suddenly, effectively barrier strip electric lead porcelain knob swings, guarantee that isolating switch porcelain knob (upper cap) charged position and staff keep enough safe distances, make the charged position of isolating switch porcelain knob and isolating switch ground connection platform beam keep safe enough distance, do not discharge, effectively prevent electric arc burn, avoid personnel get an electric shock injures and deaths and power grid accident.
Meanwhile, support and insulated guardrail are simple in structure, and convenient disassembly, together with insulated guardrail may be folded on support, is convenient to carrying and uses.

The specific embodiment
As shown in Fig. 1-6, this isolator operation safety device, comprise two supports 1, described support 1 is welded by two horizontal square tubes 101 and two vertical square tubes 102, in two horizontal square tubes 101, be respectively equipped with the anchor ear 2 being fixed together for the cement pole 8 with isolating switch below, two vertical square tubes 102 of described support 1 are utilized respectively the hinged insulated guardrail 3 of folding 4, and described insulated guardrail 3 is grid structure.Support 1 and insulated guardrail 3 are selected respectively rigid material and the insulation materials of intensity, toughness high-quality, have tough and tensile resistance to deformation intensity.On two stands 1, two relative insulated guardrails 3 utilize latch 6 to connect.Described insulated guardrail 3 is provided with socket 5, and described socket 5 is provided with stopper slot 7, so that coordinate to realize with latch 6, insulated guardrail 3 stable is connected or separated.
It is the limit (guaranteeing to require in < < electric power safety working regulation > > equipment live position to human body, minimum safe distance over the ground) according to operating personnel's normal operating scope of activities that the present invention assembles rear appearance and size: length is minimum is 2000mm, width minimum is 1350mm, highly minimum is 1500mm, in the present embodiment, adopt length 2000mm, width 1350mm, height 1500mm.Wherein the minimum 1350mm of horizontal square tube 101 length, indulges the minimum 1650mm of square tube 102 length, and anchor ear 2 diameter 300mm(are according to cement pole 8 diameters).The highly minimum 1500mm of insulated guardrail 3, the minimum 1000mm of width.
During staff's disconnecting switch operation, two stands 1 utilizes anchor ear 2 and the cement pole 8 of isolating switch below to be fixed together, then the insulated guardrail on two stands 13 is launched, and two insulated guardrails 3 of respective side utilize latch 6 to be connected and fixed.After being used to complete, extract latch 6, unload lower carriage 1.Support 1 can not unload yet, and insulated guardrail 3 is folded to support 1 side, so that reuse.
