Abstract
The utility model relates to a novel insulation pin-replacing device and belongs to the technical field of power grid maintenance facilities. The device comprises two parts including a pin-replacing device head and an insulation operating lever, wherein the pin-replacing device head comprises a vertical arm, pin-assembling teeth, a pin-disassembling groove, a screw-fixing hole and a clamping groove, wherein the T-shaped pin-assembling teeth integrally made with the vertical arm consisting of an upper tooth and a lower tooth, the teeth length is 3.5-4cm, and the distance between the teeth and the tooth arm is 4.5-5cm; the pin-disassembling groove adopting a ladder-shaped groove is formed at the top end of the tooth arm, the width of the groove port is 1.4cm, the width of the groove bottom is 1.5cm, and the depth of the groove is 0.2cm; and the screw-fixing hole and the clamping groove are positioned at the lower end of the vertical arm. The insulation operating lever comprises an insulation level, a fixing groove, a fixing screw and a fixing pin, wherein the fixing groove is formed at the upper end of the insulation level; the fixing screw and the fixing pin are arranged in the fixing groove; the pin-replacing device head is fixed in the fixing groove on the insulation operating level via the fixing screw; and the clamping groove at the lower end of the vertical arm is meshed with the fixing pin in the fixing groove, so as to play a fixing role. The novel pin-replacing device has simple structure and low construction cost, can be used on a 220 kV split conductor circuit, and can reduce interrupted power supply to users.
Description
Technical field
The utility model relates to electric power overhaul equipment technical field, and the pin device is made in especially a kind of novel insulation.
Background technology
Along with the develop rapidly of urban distribution network, the phase bundle conductor of 220kV circuit has obtained using gradually, and quantity constantly increases, because construction technology changes to some extent, existing tools for live working can not adapt to its upkeep operation fully.More the changing jobs of straight line pole insulator string that the pin device can not be suitable for the phase bundle conductor beaten in used insulation at present, can only take when changing to have a power failure and carry out as needs, having a power failure then means the reduction of power supply reliability and the minimizing of economic benefit, also can damage our corporate image.If we can finish the replacing to the straight line pole insulator string of phase bundle conductor under charged situation, just can address these problems.
Summary of the invention
The utility model overcomes above technical deficiency, provides a kind of novel insulation that can change the insulator of 35kV circuit straight line pole under the situation that circuit does not have a power failure to make the pin device.
The technical solution of the utility model is: the pin device is made in novel insulation, by beating pin device head, insulating bar two parts, wherein, beating pin device head is made up of upright arm, dress pin tooth, write off groove, fixing screw hole, draw-in groove, dress pin tooth is T-shaped and upright arm is made one, divides two teeth up and down, the long 3.5-4cm of tooth, the distance between tooth and tooth arm is 4.5-5cm; The write off groove is located at the top of tooth arm, is dovetail groove, slot opening 1.4cm, bottom width 1.5cm, dark 0.2cm; Fixing screw hole and draw-in groove are positioned at the lower end of upright arm.Insulating bar comprises by insulating bar, holddown groove, hold-down screw, steady pin and forming that the insulating bar upper end is provided with holddown groove, establishes hold-down screw and steady pin in the holddown groove.Beat pin device head and be fixed on by hold-down screw in the holddown groove of insulating bar upper end, fixation is played in the draw-in groove of upright arm lower end and the steady pin interlock in the holddown groove.During use, take off " M " pin of need safeguarding or changing, load onto " M " pin of replacing or safeguarding by dress pin tooth then and get final product by the write off groove.
The utility model realized to the insulation make the pin device improvement, simple in structure, cheap, can be in the application on the 220kV bundle conductor circuit.
