Description

Technical Field

[0001] The utility model belongs to the technical field of fault indicators, and particularly relates to a single-phase grounding line fault indicator for a 10kV system. Background Art

[0002] A single-phase grounding line fault indicator for a 10kV system is a device used to monitor and display single-phase grounding faults in a 10kV power system. Its main function is to monitor the lines in the power system in real time. When a single-phase grounding fault occurs in the system, it can give an alarm in time and display the fault location, so that the operation and maintenance personnel can quickly locate and repair it.

[0003] In the utility model patent with the patent authorization announcement number CN218445924U, a transmission line grounding fault troubleshooting alarm is disclosed, which includes a circuit fault detector. Two fixing frames are symmetrically and fixedly connected to the top wall of the circuit fault detector. Through holes are formed between the upper side walls of the fixing frames. A connecting shaft is rotatably connected to the inner side wall of the through hole. A loudspeaker is arranged above one side of the front side wall of the circuit fault detector. The two connecting shafts are symmetrically arranged and a same wireless display is fixedly connected between the opposite side walls.

[0004] However, the existing single-phase grounding line fault indicators for 10kV systems also have certain deficiencies. First of all, most of the existing single-phase grounding line fault indicators for 10kV systems simply use a plug-in method to connect and use the cables. Due to the influence of external factors such as vibration, the problem of cable loosening is likely to occur.

[0005] Secondly, most of the existing single-phase grounding line fault indicators for 10kV systems use heat dissipation grooves, etc. to dissipate heat from the indicator. Due to the poor effect of natural ventilation and heat dissipation, the problem of poor heat dissipation of the electrical components inside the indicator is likely to occur. Summary of the Invention

[0006] The purpose of the utility model is to provide a single-phase grounding line fault indicator for a 10kV system, which solves the problem that most of the existing single-phase grounding line fault indicators for 10kV systems simply use a plug-in method to connect and use the cables, and due to the influence of external factors such as vibration, the problem of cable loosening is likely to occur; and solves the problem that most of the existing single-phase grounding line fault indicators for 10kV systems use heat dissipation grooves, etc. to dissipate heat from the indicator, and due to the poor effect of natural ventilation and heat dissipation, the problem of poor heat dissipation of the electrical components inside the indicator is likely to occur.

[0007] To achieve the above object, the present utility model provides a single-phase grounding line fault indicator for a kV system, including a display body. A display panel is arranged on the front surface of the display body. A plurality of uniformly distributed heat dissipation grooves are opened at the upper end of the display body. Four uniformly distributed cables are arranged on the back surface of the display body. A fixing plate is fixedly connected to the back surface of the display body. A telescopic plate is slidably connected to the inner wall of the fixing plate. A clamping sleeve is fixedly connected to the end surface of the telescopic plate close to the cable side. The clamping sleeve contacts the cable. An end plate is fixedly sleeved on the outer side of the telescopic plate. A first spring is welded to the end surface of the end plate close to the fixing plate side. The other end of the first spring is welded to the fixing plate. A heat dissipation mechanism is arranged at the left end of the display body.

[0008] The principle of the present utility model is as follows: By pushing the telescopic plate to move away from the cable, the telescopic plate stably moves along the inner wall of the fixing plate, drives the end plate to move, and the first spring deforms. Then, the cable is pushed into the insertion end of the display body, and the telescopic plate is released to enable the first spring to restore its deformation, so as to drive the telescopic plate to drive the clamping sleeve to move. Finally, the clamping sleeve contacts the cable to clamp and limit the cable, thereby improving the stability of cable insertion.

[0009] Through the setting of the heat dissipation fan, the electrical components inside the display body can be cooled. Under the action of the filter screen, dust and other impurities in the air can be filtered out. The end rod can be pushed upward to drive the filter screen to move, and the second spring deforms, so that the filter screen disengages from the inner side wall of the installation shell. Then, the end rod is released to enable the second spring to restore its deformation, so as to drive the filter screen to contact and impact the inner side wall of the installation shell, causing the filter screen to vibrate and remove dust, so as to ensure the flow effect of the filter screen.

[0010] The beneficial effects of the present utility model are as follows: Through the deformation of the first spring in this solution, the telescopic plate can drive the clamping sleeve to clamp and limit the cable. Under the action of the friction grooves, the clamping stability of the clamping sleeve can be improved, avoiding the problem that the cable connected by the plug-in method is prone to vibration and loosening. Through the setting of the heat dissipation fan, the display can be quickly cooled. Under the action of the filter screen, dust and other impurities in the air can be filtered out. Under the structures of the end rod and the second spring, the filter screen can be vibrated to remove the impurities attached to the filter screen, thereby ensuring the flow effect of the filter screen.

[0011] Further, there are two fixing plates, and the two fixing plates are symmetrically distributed on the display body. Through the setting of the fixing plates, they can be used for the installation and support of subsequent components such as the telescopic plate.

[0012] Further, a plurality of friction grooves are opened on the inner side wall of the clamping sleeve, and the plurality of friction grooves are uniformly distributed on the clamping sleeve. Through the setting of the friction grooves, the friction effect of the inner side wall of the clamping sleeve can be improved.

[0013] Furthermore, a plurality of first springs are provided, and the plurality of first springs are evenly distributed on the end plate. By providing the first springs, the end plate can be tightly pressed for use.

[0014] Furthermore, the heat dissipation mechanism includes a mounting shell. The left end of the display body is fixedly connected to the mounting shell. A heat dissipation fan is installed on the inner side wall of the mounting shell through a support member. A fixing rod is fixedly connected to the inner side wall of the mounting shell and located below the heat dissipation fan. A second spring is welded to the lower side of the fixing rod, and the other end of the second spring is welded to a filter screen. The filter screen is in contact with the mounting shell. By providing the heat dissipation fan, the electrical components inside the display body can be heat-dissipated. Under the action of the filter screen, dust and other impurities in the air can be filtered out. And in cooperation with the deformation of the second spring, the filter screen can be continuously oscillated to remove dust to ensure the flow effect of the filter screen.

[0015] Furthermore, the overall shape of the filter screen is rectangular, and the filter screen is formed by weaving stainless steel wires. By providing the stainless steel wire material, the filter screen can have good durability.

[0016] Furthermore, an end rod is fixedly connected to the lower end of the filter screen. The end rod is made of rubber. By providing the end rod, it is convenient to push the filter screen to move, and the rubber material has a good use feel. BRIEF DESCRIPTION OF THE DRAWINGS
