Abstract
The utility model discloses a multi-purpose safety clamp for transformer station operation, comprising a clamping head and a clamping handle, wherein the clamping head and the clamping handle are symmetrically arranged in a shape of scissors and are connected with each other integrally; and the corresponding internal sides of the clamping head and the clamping handle are provided with at least one group of concave arc-shaped clamping troughs which are suitable for safely clamping objects of different diameter specifications. The multi-purpose safety clamp is smart in design and low in manufacturing and maintaining cost, can be carried and used conveniently, and has wide application scope. The multi-purpose safety clamp has the advantages that the danger degree of the operator on the switching operation is lightened, the external shutdown time is reduced, the non-normal state of the system is shortened, the generality of the tool is increased simultaneously, the waste of the resource is reduced, and the management on the operation tool is facilitated.
Description
Technical field:
The utility model relates to the aid that power supply transformer station uses, the particularly used operation tool of power transformation operation grid switching operation.
Background technology:
In recent years, along with the expansion day by day and the social economy of electrical network are more and more higher to the degree of dependence of electric power, the electric power system grid switching operation is also just more frequent, wherein get secondary insurance operation with regard to including a large amount of dresses, these insurances comprise operation insurance, close switch insurance, the insurance of PT secondary and direct current system insurance etc.Owing to lack special operating tool, there are the following problems when dress is gone bail for the danger: 1, dress is gone bail for when dangerous, the operations staff usually puts on insulating glove and operates, operate very inconvenient, and corner angle and the metallic bur power of insurance base puncture gloves easily, and perhaps, it is aging that strong galvano-cautery often takes place the first web part of insulating glove, the gloves thin and easy be full of cracks that becomes very easily causes operating personnel's casualty accident of getting an electric shock; When 2, directly getting secondary fuse with the hand dress, because hand is especially near apart from live part, perhaps because a plurality of insurances are too small, thereby is difficult to take off insurance apart, and causes easily and get an electric shock and short circuit; 3, operating personnel go bail for when dangerous with hand dress, in case get an electric shock, often can't independently break away from electrical body, cause that to implement rescue also very difficult, and get an electric shock injury to human body of direct current is far longer than alternating current with electric pressure.To sum up analyze, can find out that the site operation personnel is badly in need of a kind ofly getting the specific purpose tool of various insurances by dress, thereby human body contacts directly or hypotelorism with electrical body when avoiding operating, the safety of the person and equipment when assurance operates.
The utility model content:
Technical problem to be solved in the utility model provides Multi-purpose safety clamp for transformer station operation for above deficiency exactly, this protective pliers adopts epoxy resin to make scissor clamp shape, arcs of recesses insulation draw-in groove by the two ends different size, adapt to the low pressure insurance of all diameter specifications of mounting or dismounting, and the scale by clamp handle section can be used as engineer's scale and uses, and measures various insurance diameters and sized data.This insurance tonger has that volume is little, cost is low, carry and characteristics such as easy to use, highly versatile.
For achieving the above object, the technical solution used in the present invention is:
A kind of Multi-purpose safety clamp for transformer station operation comprises that scissor-shaped is symmetrical arranged and interconnective two integrated binding clip and clamp handles, and corresponding two binding clips and clamp handle inboard are equipped with at least one group of concave arc shape draw-in groove, are suitable for the insurance gripping of different-diameter specification.
Each integrated binding clip and clamp handle are made for epoxide resin material integral body, and the middle part is rotationally connected by rivet.
Two clamp handles are provided with scale labeled portion, can be used as engineer's scale according to top scale and use.
Each is organized concave arc shape draw-in groove inboard and all has wire drawing face, to increase friction, the firmly various insurances of gripping.
The beneficial effect that the utility model can reach is:
1, the utility model employing is withstand voltage makes greater than the epoxy resin insulation material of 1000M Ω greater than 1000V, resistance, dress is gone bail for when dangerous, and is because operating personnel hold the afterbody of protective pliers, far away apart from live part, thereby avoided the danger of getting an electric shock, guaranteed personal safety; The concave arc shape draw-in grooves of the different radius of the radian of many groups can fill the protective tube of getting a plurality of dissimilar, different tube diameters, and are very convenient; Increased contact friction by wire-drawing surface, high efficiency, use firm.
2, the utility model is used in 120000 grid switching operations of 25 transformer stations of my company, effect is very remarkable, only this item increases nearly 400,000 kWh of amount of power supply than using traditional free-hand operation and insulating gloves auxiliary operation to save surplus the total operating time 6000 hour, and economic and social benefit is obvious.
3, the utility model deft design, manufacturing and maintenance cost are low, carry with easy to use applied range.Not only alleviate operation personnel grid switching operation degree of danger, reduced external interruption duration, shortened system's abnormal condition, increased the versatility of instrument simultaneously, reduced the wasting of resources, also be convenient to the management of operation tool.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, two each integrated binding clips 1 of these power transformation operation multipurpose insurance pincers and pincers handle 3 are the scissors shape and are symmetrical arranged, and be rotationally connected by the rivet 2 of middle part cross-under, each integrated binding clip 1 and pincers handle 3 are made greater than the epoxy resins insulation integral body of 1000M Ω greater than 1000V, resistance for withstand voltage, two corresponding binding clips 1 and pincers handle 3 inboards are equipped with one group of concave arc shape draw-in groove 4, concave arc shape draw-in groove 4 inboards all have wire drawing face 6, two pincers handles 3 are provided with scale sign portion 5, can be used as engineer's scale according to top scale and use.This protective pliers is applicable to that the pottery in the various low pressure AC and DC of power system loop insures, the auxiliary operation of the installation and removal of glass tube insurance.During operation, according to the size of protective tube caliber, select binding clip 1 or clamp handle 3 clampings, concave arc shape draw-in groove 4 is opened to needs size, makes wire-drawing surface 6 clamp insurance, outwards firmly, insurance can be unloaded; The order of installation insurance and the reversed in order that unloads insurance.Need to prove: during such as needs operation improving high-tension fuse, increase the length of clamp handle 3, and enlarge concave arc shape draw-in groove 4 arcs footpath, and do withstand voltage and this two test of insulaion resistance, guarantee the security of operation.The total length of this protective pliers will meet the security regulations length of electrical production safety work order simultaneously.
