Description

Technical Field

[0001] The present invention belongs to the field of line loss detection in a transformer substation, and in particular relates to a device for detecting abnormal line loss in a transformer substation. Background Art

[0002] Low-voltage area refers to a single area that uses a public transformer to draw out loads to supply electricity to various users, with a single or multiple transformers as the statistical standard. Line loss refers to the electric energy lost in the transmission power grid, transformation, distribution and other links after the electric energy is generated from the power plant. The line loss of low-voltage area includes three types: fixed loss, variable loss and other loss.

[0003] The degree of line loss directly affects every aspect of the operation of the entire power grid system, so it is of particular importance. When detecting line loss, the staff will use the detection device to measure the transformer, and then obtain data to judge the line loss situation. The existing detection device lacks a protective structure and has poor protection effect. During the transportation and handling process where the staff constantly changes the detection area, collisions and accidental falls often occur and damage occurs. Summary of the invention

[0004] In order to address the deficiencies in the prior art, the present invention aims to provide a device for detecting abnormal line loss in a substation, which can effectively protect the detector body, improve the problem that the existing detection device lacks a protective structure and is easily damaged by collision during transportation and handling, thereby increasing the service life of the detection device.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A device for detecting abnormal line loss in a substation comprises a detector body and a detection box, wherein a box cover is provided at the upper opening of the detection box, a mounting plate is horizontally movably provided at the lower interior of the detection box, and the detector body is fixedly mounted on the mounting plate; a lower shock-absorbing assembly is provided below the mounting plate, and a plurality of side shock-absorbing assemblies are symmetrically provided on the inner wall of the detection box above the mounting plate, the side shock-absorbing assemblies cooperate with the side surfaces of the detector body, an elastic pressure piece is installed below the box cover, and the elastic pressure piece abuts against the upper part of the detector body; one side of the box cover is hinged at the opening of the detection box, and the box cover and the detection box are fixedly connected by a lock.

[0006] Furthermore, the lower shock-absorbing assembly includes a first limit rod and a first spring. A first through hole is vertically penetrated on the mounting plate. The lower end of the first limit rod is fixed to the bottom of the detection box. The first limit rod movably penetrates the first through hole and extends upward, and a first limit block is fixed to the upper end; the first spring is sleeved on the first limit rod under the mounting plate, and the upper and lower ends of the first spring are respectively abutted against the detection box and the mounting plate.

[0007] Furthermore, there are four lower shock absorbing assemblies, which are respectively arranged at the four corners of the mounting plate.

[0008] Furthermore, the side shock absorbing assembly includes a fixed plate, a horizontal slide plate, a connecting rod, a vertical plate and an abutment plate. The fixed plate is horizontally fixed on the side wall of the detection box above the mounting plate, the horizontal slide plate is horizontally slidably mounted on the fixed plate, the vertical plate and the abutment plate are vertically arranged at the end of the horizontal slide plate away from the side wall of the detection box, the vertical plate is vertically fixed to the horizontal slide plate, the abutment plate is connected to the vertical plate through a spring assembly, and the abutment plate abuts against the side wall of the detector body; the lower end of the connecting rod is rotatably connected to the mounting plate, and the upper end of the connecting rod is inclined toward the side wall of the detection box and rotatably connected to the horizontal slide plate.

[0009] Furthermore, the spring assembly includes a second limiting rod and a second spring. A second through hole is horizontally penetrated through the vertical plate. One end of the second limiting rod is horizontally fixed to the abutment plate. A second limiting block is fixed on the other end of the second limiting rod that movably penetrates the second through hole and extends outward. The second spring is sleeved on the second limiting rod and abuts between the vertical plate and the abutment plate.

[0010] Furthermore, a slide rail is horizontally installed on the fixed plate, and the horizontal slide plate is fixedly connected to a track slider of the slide rail.

[0011] Furthermore, the elastic pressing piece includes a pressing plate and a third spring. The pressing plate is horizontally movably arranged below the box cover, and two ends of the third spring are respectively fixedly connected to the upper end of the pressing plate and the bottom of the box cover.

[0012] Furthermore, a gasket is fixedly provided at the bottom of the pressing plate, and the gasket abuts against the upper end of the detector body.

[0013] Furthermore, a vent is provided in the middle of the mounting plate, and the detector body is fixedly mounted at the vent of the mounting plate.

[0014] Furthermore, a heat dissipation fan is installed on the side wall of the detection box, and an air inlet of the heat dissipation fan is connected to the detection box cavity below the mounting plate.

[0015] The present invention has the following beneficial effects: 1. When the present invention is used normally, the detector body is clamped and fixed by the abutment plates on both sides under the action of the elastic force of the second spring. When the device is bumped or falls, causing the detector body to press the mounting plate downward, the two connecting rods rotate and swing to perform a pulling action, which will pull the horizontal slide toward the middle, causing the vertical plate to move closer to the detector body, and further squeeze the second spring, so that the abutment plate further clamps the detector body, and the horizontal shaking of the detector body will be absorbed by the second springs on both sides, thereby effectively preventing the detector body from shaking left and right in the detection box during the bumping process, and playing an effective shock-absorbing and fall-proof role.

[0016] 2. When the device is performing line loss detection, the heat dissipation fan can be used to discharge the hot air discharged from the heat dissipation holes of the detector body through the vents, thereby effectively improving the heat dissipation capacity of the detector body and avoiding equipment downtime caused by overheating.

[0017] 3. When the detection device is transported and moved with the staff's detection area, if it encounters a bump or drop, when the detector body presses the mounting plate downward, under the limit of the first limit rod, the mounting plate will press the first spring downward, and the first spring will absorb the vibration pressure from the detector body, thereby playing an effective shock-absorbing and anti-fall role.

[0018] 4. When the test is completed and the box cover is closed, the upper pressure plate will abut against the top of the detector body. Under the action of the third spring, a downward force is applied to the detector body, causing the mounting plate to move downward to squeeze the first spring, and through the pulling of the connecting rod, the horizontal slide plate and the vertical plate are driven to move, squeezing the second spring, and further clamping the detector body through the abutment plate, so that the first spring, the second spring and the third spring are all in a certain degree of compression state. When a bump or fall occurs, the vibration force of the detector body can be effectively absorbed by the three springs, thereby significantly improving the device's anti-fall and anti-collision capabilities.

[0019] 5. A gasket is fixed at the bottom of the pressure plate. The gasket is made of foam board or rubber board. The gasket has a certain thickness and is crimped on the edge of the upper surface of the detector body. It can effectively prevent the pressure plate from causing damage to the dial and other structures above the detector body when it is crimped on the detector body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-5As shown, the present invention proposes a device for detecting abnormal line loss in a substation, comprising a detector body 5 and a detection box 2, a box cover 1 is provided at the opening above the detection box 2, the rear side of the box cover 1 is hinged at the opening of the detection box 2, and the box cover 1 is fixedly connected to the front side of the detection box 2 by a lock 3, so that the opening and closing operation of the box cover 1 can be more convenient.

[0023] A mounting plate 22 is horizontally movable at the lower part of the detection box 2, and the detector body 5 is fixed in the middle of the mounting plate 22. A vent 220 is provided in the middle of the mounting plate 22, and threaded holes are provided around the vent 220. The bottom of the detector body 5 is fixed in the threaded holes by bolts to effectively fix the detector body 5. The detector body 5 is fixed at the vent 220 of the mounting plate 22, and the heat dissipation holes on the detector body 5 correspond to the vent 220.

[0024] A heat dissipation fan 21 is installed on the side wall of the detection box 2, and the air inlet of the heat dissipation fan 21 is connected to the cavity of the detection box 2 below the mounting plate 22. When the device performs line loss detection, the heat dissipation of the heat dissipation fan 21 can be used to discharge the hot air discharged from the heat dissipation holes of the detector body 5 to the outside through the vent 220, thereby effectively improving the heat dissipation capacity of the detector body 5 and avoiding the equipment downtime caused by overheating.

[0025] A lower shock absorbing assembly is provided below the mounting plate 22. There are four lower shock absorbing assemblies, which are respectively provided at the four corners of the mounting plate 22. The lower shock absorbing assembly includes a first limiting rod 62 and a first spring 63. A first through hole is vertically penetrated through the mounting plate 22. The lower end of the first limiting rod 62 is fixedly provided at the bottom of the detection box 2. The upper end of the first limiting rod 62, which movably penetrates the first through hole and extends upward, is fixedly provided with a first limiting block 61 (the diameter of the limiting block is larger than the first through hole). The first spring 63 is sleeved on the first limiting rod 62 below the mounting plate 22, and the upper and lower ends of the first spring 63 are respectively in contact with the detection box 2 and the mounting plate 22.

[0026] When the detection device is transported and moved as the staff moves around the detection area, if it encounters a bump or falls, when the detector body 5 presses the mounting plate 22 downward, under the limit of the first limit rod 62, the mounting plate 22 will press the first spring 63 downward, and the first spring 63 will absorb the vibration pressure from the detector body 5, thereby playing an effective shock-absorbing and anti-fall role.

[0027] Two side shock absorbing assemblies 4 are symmetrically arranged on the inner wall of the detection box 2 above the mounting plate 22. The side shock absorbing assemblies cooperate with the side of the detector body 5. The side shock absorbing assemblies 4 include a fixed plate 41, a horizontal slide 42, a connecting rod 45, a vertical plate 43 and an abutting plate 44. The fixed plate 41 is horizontally fixed on the side wall of the detection box 2 above the mounting plate 22, and the horizontal slide 42 is horizontally slidably installed on the fixed plate 41. Specifically, a slide rail is horizontally installed on the fixed plate 41, and the horizontal slide 42 is fixedly connected to the track slider of the slide rail, so as to effectively improve the movement stability of the horizontal slide 42. The vertical plate 43 and the abutting plate 44 are vertically arranged at the end of the horizontal slide 42 away from the side wall of the detection box 2. The vertical plate 43 is vertically fixedly connected to the horizontal slide 42, and the abutting plate 44 is connected to the vertical plate 43 through a spring assembly, and the abutting plate 44 abuts against the side wall of the detector body 5. In a specific implementation, an abutment plate 44 is provided between the two vertical plates 43 on the same side of the left and right sides, and the two spring assemblies abut against the same abutment plate 44 .

[0028] The lower end of the connecting rod 45 is rotatably connected to the mounting plate 22, and the upper end of the connecting rod 45 is tilted toward the side wall of the detection box 2 and rotatably connected to the horizontal slide plate 42. The spring assembly includes a second limiting rod 47 and a second spring 46. A second through hole is horizontally penetrated through the vertical plate 43. One end of the second limiting rod 47 is horizontally fixedly connected to the abutting plate 44. A second limiting block 471 is fixedly provided on the other end of the second limiting rod 47 that movably penetrates the second through hole and extends outward. The second spring 46 is sleeved on the second limiting rod 47 and abuts between the vertical plate 43 and the abutting plate 44.

[0029] During normal use, the detector body 5 is clamped and fixed by the abutment plates 44 on both sides under the elastic force of the second spring 46. When the device is bumped or falls, causing the detector body 5 to press the mounting plate 22 downward, the two connecting rods 45 rotate and swing to perform a pulling action, which will pull the horizontal slide plate 42 toward the middle, causing the vertical plate 43 to move closer to the detector body 5, and further squeeze the second spring 46, so that the abutment plates 44 further clamp the detector body 5, and the shaking of the detector body 5 in the horizontal direction will be absorbed by the second springs 46 on both sides, thereby effectively preventing the detector body 5 from shaking left and right in the detection box 2 during the bumping process, and playing an effective shock-absorbing and fall-proof role.

[0030] An elastic pressing piece is installed under the box cover 1, and the elastic pressing piece abuts against the top of the detector body 5. The elastic pressing piece includes a pressing plate 11 and a third spring 12. The pressing plate 11 is horizontally movable under the box cover 1, and the two ends of the third spring 12 are respectively fixed to the upper end of the pressing plate 11 and the bottom of the box cover 1.

[0031] When the detection is completed and the box cover 1 is closed, the upper pressure plate 11 will abut against the top of the detector body 5. Under the elastic force of the third spring 12, a downward force is applied to the detector body 5, so that the mounting plate 22 moves downward to squeeze the first spring 63, and through the pulling of the connecting rod 45, the horizontal slide plate 42 and the vertical plate 43 are driven to move, squeezing the second spring 46, and further clamping the detector body 5 through the abutment plate 44, so that the first spring 63, the second spring 46 and the third spring 12 are all in a certain degree of compression state. When a bump or fall occurs, the vibration force of the detector body 5 can be effectively absorbed by the three springs, thereby significantly improving the anti-fall and anti-collision ability of the device.

[0032] A gasket 111 is fixedly provided at the bottom of the pressure plate 11, and the gasket 111 is abutted against the upper end of the detector body 5. The gasket 111 is made of foam board or rubber board, has a certain thickness, and is pressed against the edge of the upper surface of the detector body 5, which can effectively prevent the pressure plate 11 from causing damage to the dial and other structures above the detector body 5 when the pressure plate 11 is pressed against the detector body 5.

[0033] When the present invention is used, when not in the detection operation state, the box cover 1 is in a closed state, and under the elastic force of the third spring 12, the upper pressure plate 11 will apply a downward force to the detector body 5, so that the mounting plate 22 moves downward to squeeze the first spring 63, and through the pulling of the connecting rod 45, the vertical plate 43 squeezes the second spring 46, so that the first spring 63, the second spring 46 and the third spring 12 are all in a certain degree of compression state. When a bump or fall occurs, the vibration force of the detector body 5 can be effectively absorbed by the three springs, thereby significantly improving the anti-fall and anti-collision capabilities of the device.
