Description

Technical Field

[0001] The present invention relates to the technical field of power distribution network fault processing devices, and in particular to a novel power distribution network fault processing device. Background Art

[0002] The power distribution network of the power system involves numerous power consuming units. With the growth of the power system and the continuous increase in users, faults in the distribution network also occur frequently. In remote areas, the harsh environment makes repair work difficult, so a distribution network fault handling device is born. However, during the use of the distribution network fault handling device, faults caused by excessive voltage are likely to cause parasitic disasters. For this reason, a power grid distribution network fault handling device is needed to handle the fault. The fault handling device of the prior art fixes the distribution network line with a bolt in the ports at both ends of the fault handling device. Since the distribution network line needs to be fixed, the bolts need to be pressed and fixed to the distribution network line by a screwdriver, which is cumbersome to operate and inconvenient to fix the distribution network line.

The connecting device 4 and the second connecting device 5 have the same structure and are arranged opposite to each other. The first connecting device 4 is composed of a protective cover 41, a connecting plate 42, a fixing hole 43, a threaded hole 44, a fixing cover 45, a fixing plate 46, a screw 47 and a square groove 48. The connecting plate 42 passes through the protective cover 41 horizontally, and a fixing hole 43 is provided at the right end of the connecting plate 42. The fixing cover 45 is sleeved on the right side of the connecting plate 42. A fixing plate 46 is provided at the left end of the fixing cover 45, and the screw 47 passes through the fixing plate 46 and is threadedly connected to the threaded holes 44 on the front and rear sides of the protective cover 41. The left sides of the protective cover 41 and the connecting plate 42 are fixed to the detection box 2, and the left end of the connecting plate 42 is connected to the fuse 7 through the wire 6.

[0030] Among them, the screw rod 47 is composed of a knob 471, a support rod 472, a thread 473, a limit plate 474 and a fixing bolt 475. A through hole is horizontally arranged in the middle of the knob 471, and the right end of the support rod 472 passes through the fixing plate 46 and is inserted into the through hole of the knob 471. The fixing bolt 475 extends into the right end of the through hole of the knob 471 and is threadedly connected with the support rod 472.

A thread 473 is arranged on the left end of the support rod 472, and is threadedly connected with the threaded holes 44 on the front and rear sides of the right end of the protective cover 41 through the thread 473.

[0031] The weight of the first connecting device 4 and the second connecting device 5 is less than 5 kg, so as to avoid inconvenience in carrying due to excessive weight.

[0032] The relative humidity of the working environment in the housing 1 is 5% to 95%, which is suitable for use in a variety of humidity environments.

[0033] There are two threaded holes 44 and two screw rods 47 , which is beneficial for firmly connecting the protective cover 41 and the fixed cover 45 .

[0034] The ambient temperature of the working environment in the housing 1 is -25 to 55° C. to prevent parts from not being able to operate due to excessively high or low temperatures.

[0035] The protection level of the box shell 1 is IP44, so that the box shell 1 is not easily damaged.

[0036] The right end of the support rod 472 is square-shaped, and the inner wall of the knob 471 matches the support rod 472 , which is conducive to limiting the rotation of the support rod 472 and preventing the support rod 472 from being unable to rotate with the knob 471 .

[0037] The inner width of the fixing cover 45 is greater than the thickness of the connecting plate 42 by 0.2 cm, which is conducive to enabling the fixing cover 45 to drive the power distribution network line to clamp the connecting plates 42 .

[0038] The protective cover 41, the fixing cover 45 and the knob 471 are all made of PVC plastic material, which is light, not easy to be damaged, and has good insulation effect.

[0039] The conductor 6 and the connecting plate 42 are both made of copper, which has high hardness and good conductivity.

[0040]

[0041] According to the above table, the conductor 6 and the connecting plate 42 of the present invention are both made of metal copper, which has the advantage of good conductive effect.

[0042] The fuse 7 described in this patent is also called a current fuse. The IEC127 standard defines it as a "fuse", which mainly plays an overload protection role. If the fuse is correctly placed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain height and temperature, thereby protecting the safe operation of the circuit.

[0043] Working principle: Before use, first put the tools required for the power distribution network line into the drawer 8. When using, first connect the power distribution network line, remove the protective rubber on the outside of the power distribution network line, and then extend the power distribution network line from the bottom end of the connecting plate 42 into the fixing hole 43, and extend it, then squeeze the fixing cover 45 inward, bend the top of the power distribution network line through the fixing cover 45, and a square groove 48 is provided at the bottom of the fixing cover 45 to prevent the bottom of the power distribution network line from bending and causing easy breakage, and then rotate the knob 471. Since the right end of the support rod 472 is square in shape and rotated The inner wall of the button 471 is matched with the support rod 472, so that the rotation of the knob 471 drives the support rod 472 to rotate, and the support rod 472 is threadedly locked with the threaded hole 44 of the protective cover 41 through the thread 473, and the fixing plate 46 at the left end of the fixing cover 45 is fixed to the protective cover 41, so that the fixation of the distribution network line can be completed, and then the drawer 9 is opened by the handle 9, and the detection tool is used to perform fault detection on the distribution network. When a fault such as overvoltage occurs in the circuit, the high voltage will increase the temperature of the fuse 7, and the fuse 7 has a low melting point. After reaching a certain temperature, it will automatically melt, and preliminary automatic fault processing is performed.
