The invention discloses an insulated T-shaped socket spanner. The insulated T-shaped socket spanner comprises a handle, a connecting rod, an insulated rod, a socket joint and a socket, wherein the handle is a transverse rod; one end of the connecting rod is vertically connected with the handle, and the other end of the connecting rod is fixedly connected with the socket joint; the socket joint is clamped together with the socket; the insulated rod is embedded into the connecting rod; both the handle and the connecting rod are coated with an insulating layer. The insulated T-shaped socket spanner has a dual insulated structure, is high in insulating property, can go deep into narrow places where an ordinary spanner is difficult to operate, and is wide in application range.
Description
Technical field
The present invention relates to a kind of box spanner for controller switching equipment hotline maintenance.
Background technology
At present, the maintenance of controller switching equipment need to have a power failure in a big way, and the switch maintenance (exchange) at special low-voltage distribution station needs whole section of bus to have a power failure, and can not ensure power supply reliability.Therefore need these controller switching equipments to carry out hotline maintenance operation, in operation, must use box spanner, but common box spanner have insulating properties low, contact the shortcomings such as unreliable, bolt easily falls, adaptability is low, use occasion is limited, easily cause the potential safety hazards such as device damage, short circuit grounding and personnel's electric shock.Therefore, in order effectively to change current controller switching equipment interruption maintenance present situation on a large scale, for safety in production provides effective support, developing a kind of good insulating, widely applicable box spanner, is the direction that the applicant makes great efforts.
Summary of the invention
The object of the present invention is to provide the T-shaped box spanner of a kind of insulation, it has double insulation structure, and insulating properties is high, can go deep into narrow, the not easy-operating occasion of common wrench, widely applicable.
The technical scheme that realizes above-mentioned purpose is:
The T-shaped box spanner of a kind of insulation, comprises handle, connecting rod, insulating bar, muff joint and sleeve, wherein:
Described handle is a cross bar;
One end of described connecting rod and described handle vertical connection, the other end and described muff joint are fixedly connected;
Described muff joint and described sleeve clamping;
Described insulating bar is embedded in described connecting rod;
Described handle and connecting rod be the outer layer insulating that covers all.
In the T-shaped box spanner of above-mentioned insulation, between described connecting rod and insulating bar, fix by punching screw.
In the T-shaped box spanner of above-mentioned insulation, described handle and connecting rod are one-body molded.
In the T-shaped box spanner of above-mentioned insulation, the end that joins of described connecting rod and handle is 1:2 with the ratio of distances constant at described handle two ends.
In the T-shaped box spanner of above-mentioned insulation, the end that joins of described connecting rod and handle is 230mm～280mm with the distance of described insulating bar.
The invention has the beneficial effects as follows: insulating properties of the present invention are high.Compared with traditional T-shaped box spanner, except insulating cover, also installed additional in addition can withstand voltage 3kV insulating bar, can, by charged position and non-charged position isolation, further ensure the insulating properties of Work tool.Meanwhile, contact is reliable, can prevent that operating process sleeve and bolt from falling problem.Sleeve inner arranges magnetisable material, guarantees to contact well with bolt in operating process, avoids electric arc to occur.And, can go deep into narrow, the not easy-operating occasion of common wrench by the connecting rod of moderate length, make to operate more labour-saving and guarantee insulation distance simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure chart of the T-shaped sleeve barrel spanner of insulation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, the T-shaped box spanner of insulation of the present invention comprises handle 1, connecting rod 2, insulating bar 3, muff joint 4 and sleeve (not shown), wherein;
Insulating bar 3 is embedded in connecting rod 2, thereby connecting rod 2 is divided into two parts, live part and non-live part when isolation operation.Between connecting rod 2 and insulating bar 3, adopt punching screw (not shown) to fix, make it possible to bear the mechanical stress applying while use.Handle 1 and connecting rod 2 are all outer covers a layer insulating, not only plays insulation and anti-skidding effect, can also avoid instrument in use because knocking, rub and impacting the spark of generation.
Connecting rod 2 is 1:2 with the end that joins of handle 1 with the ratio of distances constant at handle 1 two ends, to make the present invention meet ergonomic designs, operates comfortable.Connecting rod 2 is 230mm～280mm with the end that joins of handle 1 with the distance of insulating bar 3, more can go deep into narrow, the not easy-operating occasion of common wrench, makes to operate more labour-saving and guarantees insulation distance simultaneously.
As shown in Figure 1, in the present embodiment, the long 160mm of handle 1; The long 55mm of insulating bar 3; Muff joint 4 is up-narrow and down-wide two parts, respectively long 35mm and 40mm; The wide 15mm of connecting rod 2, connecting rod 2 is respectively 45mm and 100mm with the end that joins of handle 1 apart from handle 1 two ends, and connecting rod 2 is 240mm with the end that joins of handle 1 with the distance of insulating bar 3.
When use, block bolt with sleeve, apply external force along screw thread rotation direction at the two ends of handle 1, just can twist bolt.The material of handle 1, connecting rod 2, muff joint 4 and sleeve is all selected chrome-vanadium steel; Insulating bar 3 is made up of fire retarding epoxide resin; Between muff joint 4 and sleeve, adopt Spring Card mouth structure to fix, it is firm to contact.Sleeve inner arranges magnetisable material, guarantees to contact well with bolt in operating process, avoids electric arc to occur.
After tested, the present invention's entirety industrial frequency withstand voltage >=3000V, overall impulse withstand voltage >=5000V; Leakage current under 5 minutes industrial frequency withstand voltages: when dry state≤30 μ A, when hygrometric state≤100 μ A.The oxygen index (OI) of insulator is 35, and the oxygen index (OI) of external insulation layer is 39.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
