Description

Technical Field

[0001] The invention belongs to the technical field of discharge monitoring of electric power equipment, and in particular relates to a coupling agent patch preparation system and a coupling agent patch. Background Art

[0002] When partial discharge occurs inside the insulation of power equipment, an ultrasonic signal is generated at the same time. This signal is conducted from the partial discharge source along the insulating medium, metal parts or air to the outer casing of the power equipment, and propagates to the surrounding air through the medium and gaps. The ultrasonic partial discharge sensor determines the partial discharge of the power equipment by coupling to this signal. Therefore, the contact-type ultrasonic partial discharge online monitoring device (hereinafter referred to as "ultrasonic partial discharge monitoring device") is often used in the power system to monitor the operating status of important transformers (high-voltage transformers). Each ultrasonic partial discharge sensor is fixed to the surface of the power equipment body by "magnetic attraction + coupling agent";

[0003] The coupling agent is usually randomly squeezed out from the packaging box by the construction workers and applied to the sensor surface for bonding and fixing. However, if the amount of coupling agent used each time is too little, the sensor detection performance will be poor, and if the amount is too much, it will be wasted and may also affect the ultrasonic sensor detection performance. In order to ensure that the coupling agent application process is controllable, the inventor proposes a coupling agent patch and a method of use: Summary of the invention

The cutting knife is adapted to the shape of the cutting groove.

[0011] Furthermore, the accommodating cavity preparation structure includes a pressing protrusion arranged at the bottom of the movable plate and a pressing groove arranged at the top of the fixed platform, and the pressing protrusion is used to cooperate with the pressing groove to groove the coupling agent patch package to form an accommodating cavity.

[0012] Furthermore, the filling structure includes a pump disposed on the top of the movable plate, the output end of the pump passes through the bottom of the pressed protrusion and communicates with the interior of the accommodating cavity, and the input end of the pump is connected to a coupling agent tank through a hose.

[0017] The accommodating cavity is formed by the shape and structure of the coupling agent patch package, and can accommodate a certain amount of coupling agent while maintaining the coupling agent patch package.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Start the electric push rod 14, which drives the movable plate 15 to move downward; when the movable plate 15 moves, it drives the positioning strip 21 to move downward, and the positioning strip 21 moves downward to push the middle part of the tinfoil into the space between the two arc pressure surfaces 22, pushes the flexible clamping strip 23 away, and then bends and shapes in the arc-shaped shaping bin 24, and drives the movable plate 15 upward in the reverse direction, which drives the positioning strip 21 to move upward. The tinfoil is separated from the positioning strip 21 due to the bending and shaping and the resistance of the two flexible clamping strips 23, and the tinfoil is fixed; The plate 15 drives the pressing protrusion 51 to move downward, and the pressing protrusion 51 presses the tin foil into the pressing groove 52, so that the tin foil is shaped to form a receiving cavity. By prefabricating the receiving cavity, it is prevented that the coupling agent is squeezed and scattered when the movable table 13 and the fixed table 12 are attached, thereby preventing the coupling agent from being scattered beyond the cutting range after slitting, causing pollution and waste. After the receiving cavity is made, the movable plate 15 is reversely started to move upward, and the pressing protrusion is moved and separated from the receiving cavity, and the pump 61 is started to pump the coupling agent in the coupling agent tank 62 into the receiving cavity according to a fixed dosage;

[0020] The coupling agent patch is shaped like a coin and is completely closed. It contains a standard dose of coupling agent. When using it, first tear off the film cover on one side and press it on the pressure surface of the sensor, then tear off the film cover on the other side and press the sensor on the body until it is fixed. The coupling agent patch can be mass-produced, and the design of the filling structure enables the coupling agent to evenly cover the accommodating cavity, ensuring the consistent quality of each coupling agent patch; the efficiency and standardization of the use of the coupling agent can be greatly improved by controlling the sub-packaging through a pump machine, which has promotion value.

[0021] 2. Start the hydraulic cylinder 30, which pushes the connecting rod 31 to rotate. When the connecting rod 31 drives the movable platform 13 to rotate, the movable platform 13 rotates around the rotating shaft 32 thereon, and stops rotating when the linkage member 33 rotates to contact the blocking rod 35. The linkage member 33 rotates around the rotating shaft 32 connected to the fixed platform 12, and stops rotating when the movable platform 13 drives the tin foil to cover the fixed platform 12;

[0022] The connecting rod 31 rotates to drive the movable platform 13 to rotate. When the movable platform 13 rotates, the arc pressure surface 22 on the movable platform 13 rotates with the movable platform and another set of arc pressure surfaces 22 with a certain offset. In order to avoid the displacement of the tin foil due to the rotation of the arc pressure surface 22, the rotating shaft 26 is set. When the movable platform 13 rotates, the rotating shaft 26 is fixed, thereby ensuring that the tin foil has a good fixing effect.

[0023] Through the synergistic effect of the supporting structure and various supporting structures, the coupling agent can be quickly and accurately extruded onto the coupling agent patch package, thereby improving production efficiency. The positioning structure can fix the coupling agent patch package to ensure the stability and accuracy of the coupling agent patch package during operation, avoiding production problems caused by position deviation, and at the same time providing a covering structure to enable the coupling agent patch package to be flipped over.

[0024] 3. When the movable table 13 is flipped and attached to the fixed table 12, the cutting knife 41 cooperates with the inner wall of the cutting groove 42 to break the tin foil, complete the separation of the coupling agent patch from the tin foil, and efficiently cut and separate the coupling agent patch according to the preset shape through precise grooving and coating, which can effectively prevent the leakage and contamination of the coupling agent. The slitting structure can efficiently cut and separate the coupling agent patch according to the preset shape through precise grooving and coating, which improves the safety and quality of the final product, simplifies the post-processing steps, and makes the production process simpler.

[0043] The covering structure is arranged on the supporting structure and is used to move the coupling agent patch packaging to wrap the coupling agent as the center to form a coupling agent patch. Through precise grooving and wrapping, the coupling agent leakage and contamination caused by the extrusion of the covering structure can be effectively prevented;

[0044] The slitting structure is arranged on the supporting structure and is used to cut and separate the coupling agent patch according to the set shape.

The movable plate 15 drives the pressing protrusion 51 to move downward, and the pressing protrusion 51 squeezes the tin foil into the pressing groove 52, so that the tin foil is shaped to form an accommodating cavity. By prefabricating the accommodating cavity, it is avoided that the coupling agent is squeezed and scattered when the movable table 13 and the fixed table 12 are attached, thereby avoiding that the coupling agent is scattered beyond the cutting range after cutting, causing pollution and waste.
