[0001] The invention relates to the field of high voltage power transmission and transformation, and in particular to a comprehensive inspection instrument for partial discharge of high voltage power equipment. Background Art

[0002] It adopts advanced anti-interference components and unique door display circuit, and has four high-frequency elliptical scanning modes. It is suitable for type and factory tests of high-voltage products, new product development tests, and quantitative tests of partial discharge of motors, mutual inductors, cables, bushings, capacitors, transformers, lightning arresters, switches and other high-voltage electrical appliances.

[0003] In the known prior art, when workers inspect and repair power equipment at heights, they hold a sensor with one hand and stick it to the surface of the power equipment, and support the detection host with the other hand to check the values. However, the detection host is heavy and puts a certain burden on the wrist, so it cannot be held for a long time. In addition, it is difficult to press the button with one hand during holding. When operating with one hand or climbing to a height with the detection host, it is easy for the fingers and body to accidentally touch the buttons, which makes it inconvenient to adjust the detection host. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a comprehensive inspection instrument for partial discharge of high-voltage power equipment. The detection host is carried and fixed by a shoulder strap, and there is no need to hold it hand-held. The staff can hold the sensor while operating the detection host. During use, accidental touching of buttons can also be prevented.

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The embodiment of the present application provides a comprehensive inspection instrument for partial discharge of high-voltage power equipment, which solves the problem that when workers repair power equipment at heights, they hold a sensor with one hand and stick it to the surface of the power equipment, and support the detection host with the other hand to check the value. However, the detection host is heavy and puts a certain burden on the wrist, so it cannot be held for a long time. In addition, it is difficult to press the button with one hand during holding. When operating with one hand or climbing to a height with the detection host, the fingers and body are prone to accidentally touch the buttons, making it inconvenient to adjust the detection host. When in use, the worker can carry the detection host on his back, which is convenient for carrying and rotating. The worker can hold the sensor while controlling the detection host, which is convenient for one-handed use, and the buttons can be blocked by a shift plate to prevent accidental touching of the buttons.

[0046] In the known prior art, the detection host is generally placed on a platform or held in the hand, and there is no problem of inconvenient button pressing. However, when testing at a high place, the staff wears the detection host with one hand and holds the sensor with the other hand to contact the power equipment. At this time, the finger that is connected to the detection host is difficult to press the button, so the staff can only put down the sensor, adjust the detection host, and then use the sensor to continue testing, which reduces work efficiency;

[0047] In the known prior art, workers are prone to accidentally touching the button during climbing and holding, which increases the number of adjustment steps and also causes squeezing damage to the button.

[0048] The technical solution in the embodiment of the present application is to solve the above technical problems. The overall idea is as follows: the button is shielded by an anti-touch device and opened when needed, which can prevent the staff from accidentally touching the button during climbing or holding.

[0049] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Reference Figure 1-8 , a comprehensive inspection instrument for partial discharge of high-voltage power equipment, comprising:

[0051] The anti-touch device 1 is configured to cover or open the button 64;

[0052] The anti-touch device 1 comprises:

[0053] A guide rail 11, the guide rail 11 is connected to the upper surface of the detection host 2, and the upper surface of the guide rail 11 is connected to a side plate 12;

[0054] The guide rail 11 is connected to a moving plate 13, a first friction groove 15 is formed through the top of the moving plate 13, and a handle 14 is connected to the upper surface of the moving plate 13;

[0055] The side plate 12 is connected to a pressure plate 17 via a first spring 16, and a second friction groove 66 is provided at the bottom of the pressure plate 17;

[0056] The guide rail 11 is connected to the second spring 18 through the vertical plate 65, and the second spring 18 is connected to the push plate 19;

[0057] The handle 14 is held and the shift plate 13 is moved toward the push plate 19. The button 64 is no longer blocked by the shift plate 13. The shift plate 13 abuts against and contacts the curved surface of the pressure plate 17. The pressure plate 17 is subjected to an upward extrusion force. The first spring 16 is compressed, and the pressure plate 17 moves upward. The shift plate 13 is squeezed under the pressure plate 17 and continues to go deeper. The first friction groove 15 and the second friction groove 66 rub against each other. The shift plate 13 squeezes the push plate 19. The second spring 18 is compressed, and the elastic force of the second spring 18 increases. The elastic coefficient of the second spring 18 is much smaller than that of the first spring. The elastic coefficient of 16, when the shift plate 13 stops moving toward the push plate 19, the second spring 18 overcomes the sliding friction of the first friction groove 15 and the second friction groove 66 under its own elastic action, and the second spring 18 moves the push plate 19 and the shift plate 13 toward the button 64. Under the combined action of elastic action and friction action, the recovery speed of the shift plate 13 is slow, which will not affect the normal use of the staff. When the staff does not press the button 64 for a long time, the shift plate 13 can automatically reset and complete the shielding of the button 64, saving time and effort;

[0058] A fixing device 3, used for fixing the detection host 2;

[0059] The fixing device 3 comprises:

[0060] The shoulder strap 31 is connected to a first connecting rope 36 through a first cross bar 33, and is connected to a second connecting rope 37 through a second cross bar 34. The bottom ends of the first connecting rope 36 and the second connecting rope 37 are connected to a placement box 71. The detection host 2 is placed in the placement box 71. The two sides of the placement box 71 are connected to a rotating shaft 74. The rotating shaft 74 is connected to a connecting plate 78 through a cylinder 76. The side of the connecting plate 78 away from the longitudinal axis of the cylinder 76 is connected to the side of the shoulder strap 31 close to the longitudinal axis of the cylinder 76.

[0061] The front side of the shoulder strap 31 is connected to a limiting belt 35;

[0062] The limiting belt 35 is made of elastic material, and the limiting belt 35 is a rubber belt;

[0063] The staff member carries the shoulder strap 31 on his back, and the shoulder strap 31 provides support for the placement box 71, so that the detection host 2 can be fixed in the placement box 71. The placement box 71 can be rotated 90 degrees. When the staff member is climbing, the placement box 71 is erected, the limiting belt 35 is lifted, and the top sleeve 62 of the placement box 71 is connected to the limiting belt 35. The top of the placement box 71 is fixed by the limiting belt 35, and the bottom of the placement box 71 is fixed by the connecting plate 78. At this time, the placement box 71 cannot fall;

[0064] When the staff needs to use the detection host 2, the top of the placement box 71 is taken out from the limiting belt 35, and the placement box 71 is fully unfolded. The first connecting rope 36 and the second connecting rope 37 pull the placement box 71, and the angle between the placement box 71 and the vertical state after the placement box 71 is unfolded is 90 degrees;

[0065] The first connecting rope 36 fixes one end of the placement box 71, and the second connecting rope 37 fixes the other end of the placement box 71, thereby completing the fixing of both ends of the placement box 71, so that the placement box 71 is evenly stressed. The placement box 71 is connected to the placement box 71 by a plurality of first connecting ropes 36 and second connecting ropes 37. When some of the first connecting ropes 36 and the second connecting ropes 37 are damaged, the stability of the placement box 71 is ensured;

[0066] In a further embodiment, a rectangular groove 63 is opened at the edge of the upper surface of the detection host 2, a button 64 is arranged at the top of the groove, the top of the button 64 is located in the same plane as the top of the detection host 2, and a sleeve 62 is connected to the middle of the lower surface of the detection host 2.

[0067] When the moving plate 13 moves along the guide rail 11 , the moving plate 13 slides on the upper surface of the detection host 2 , and the moving plate 13 does not press the button 64 ;

[0068] In a further embodiment, the push plate 19 is connected to the guide rail 11 , and the push plate 19 is arranged parallel to the shift plate 13 .

[0069] The push plate 19 can be in full contact with the shift plate 13, increasing the contact area between the two;

[0070] In a further embodiment, there are two side plates 12, and the two side plates 12 are symmetrically distributed along the transverse axis of the shift plate 13. The side plates 12 are composed of a bottom plate and a top plate. The guide rail 11 is connected to the top plate through the bottom plate. The bottom plate is an L-plate. The pressure plate 17 and the second spring 18 are both arranged below the top plate.

[0071] In a further embodiment, the pressure plate 17 is composed of a flat plate and a bent plate connected to the flat plate, and the bent plate is bent upward. When the first spring 16 is not subjected to external force, the distance from the upper surface of the flat plate to the upper surface of the detection host 2 is smaller than the distance from the upper surface of the movable plate 13 to the upper surface of the detection host 2, and the distance from the top end of the bent plate to the upper surface of the detection host 2 is greater than the distance from the upper surface of the movable plate 13 to the upper surface of the detection host 2.

[0072] When the moving plate 13 does not press the pressing plate 17 , the first spring 16 is not acted upon by external force.

[0073] When the curved surface of the bent plate contacts the moving plate 13, the moving plate 13 squeezes the bent plate and moves along the curved surface. The bent plate can play a guiding role. Under the squeezing action, the bent plate moves upward with the flat plate and the remaining bent plates. The first spring 16 is compressed to increase the pressure between the flat plate and the moving plate 13.

[0074] In a further embodiment, the first friction groove 15 and the second friction groove 66 have the same length, and the pressure plate 17 can press the shift plate 13 under the elastic force of the first spring 16 .

[0075] In a further embodiment, there are two shoulder straps 31, and the adjacent sides of the two shoulder straps 31 are connected to the two ends of the first cross bar 33 and the two ends of the second cross bar 34. The second cross bar 34 is arranged below the first cross bar 33. The bottom of one first cross bar 33 is connected to two first connecting ropes 36, and the bottom of each first connecting rope 36 is connected to the placement box 71 through the first connecting block 72. The bottom of one first cross bar 33 is connected to two second connecting ropes 37, and the bottom of each second connecting rope 37 is connected to the placement box 71 through the second connecting block 73. The two first connecting ropes 36 and the two second connecting ropes 37 are symmetrically distributed along the longitudinal axis of the placement box 71.

[0076] The first connecting rope 36 and the second connecting rope 37 are symmetrically distributed along the longitudinal axis of the placement box 71 to ensure balanced tension and improve stability;

[0077] In a further embodiment, the distance between the bottom of the limiting belt 35 and the connecting plate 78 is smaller than the height of the upright placement box 71 , and the distance between the top of the limiting belt 35 and the connecting plate 78 is larger than the height of the upright placement box 71 .

[0078] In a further embodiment, thread grooves are provided in the middle of both sides of the detection host 2, and thread rods 77 are provided in the middle of both sides of the placement box 71, and the thread rods 77 are connected to the thread grooves.

[0079] During use, the staff member puts on the shoulder strap 31, and uses the shoulder strap 31 to support the placement box 71, and fixes the detection host 2 in the placement box 71. When the staff member climbs, the placement box 71 is erected, the limiting belt 35 is lifted, and the top sleeve 62 of the placement box 71 is connected to the limiting belt 35. The top of the placement box 71 is fixed by the limiting belt 35, and the bottom of the placement box 71 is fixed by the connecting plate 78. At this time, the placement box 71 cannot fall;

[0080] When the staff needs to use the detection host 2, the top of the placement box 71 is taken out from the limiting belt 35, and the placement box 71 is fully unfolded. The first connecting rope 36 and the second connecting rope 37 pull the placement box 71, and the angle between the placement box 71 and the vertical state after the placement box 71 is unfolded is 90 degrees;

[0081] The first spring 16 is compressed, and the pressing plate 17 moves upward, and the shift plate 13 is squeezed under the pressing plate 17 and continues to go deeper, and the first friction groove 15 and the second friction groove 66 rub against each other, and the shift plate 13 squeezes the push plate 19, and the second spring 18 is compressed. When the shift plate 13 stops moving toward the push plate 19, the second spring 18 overcomes the sliding friction of the first friction groove 15 and the second friction groove 66 under its own elastic action, and the second spring 18 moves the push plate 19 and the shift plate 13 toward the button 64. Under the combined action of elastic action and friction action, the recovery speed of the shift plate 13 is slow, which will not affect the normal use of the staff. When the staff does not press the button 64 for a long time, the shift plate 13 can automatically reset and complete the shielding of the button 64, saving time and effort.

[0082] When it is necessary to squeeze the button 64 with one hand, partially insert the finger into the sleeve 62, support a corner of the detection host 2 with the palm, and the thumb can move flexibly, and the thumb is close to the button 64, so that the button 64 can be easily squeezed by the thumb;

[0083] In summary, compared with the prior art, the present invention has the following beneficial effects: it enables the staff to carry and fix the detection host 2, which is convenient for carrying and rotating; when inspecting at a high place, a placement platform is provided for the detection host 2, and the staff can hold the sensor 5 while operating the detection host 2, which is convenient for use; through the elastic action of the first spring 16 and the second spring 18, the movement of the shift plate 13 is regulated and the button 64 is blocked or opened to prevent accidental touching of the button 64.
