Description

Technical Field

[0001] This utility model relates to the technical field of reactive power compensation device components, specifically an overheat protection component for a reactive power compensation device in a substation. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. Substations within power plants are step-up substations, whose function is to step up the voltage of the electrical energy generated by generators and feed it into the high-voltage power grid.

[0003] Existing reactive power compensation devices generate a lot of heat during use. To ensure the safety of the device, it is placed inside a housing. This results in the heat generated by the device being too high to be effectively dissipated, causing it to overheat. Prolonged overheating can lead to a decline in the performance of the thyristors and even burn them out, thus reducing the effectiveness of the device.

[0004] To address this issue, we designed an overheat protection component for a substation reactive power compensation device. Utility Model Content

[0005] The purpose of this utility model is to provide an overheat protection component for a reactive power compensation device in a substation, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an overheat protection component for a reactive power compensation device in a substation, including a temperature detection element. A fixing groove is provided on the front side of the temperature detection element, and a sliding plate is slidably inserted into the fixing groove. A spring is provided between the sliding plate and the inner side wall of the fixing groove. A striker is also provided on one side of the sliding plate. An electromagnetic button is also provided on the inner side wall of the fixing groove. The striker and the electromagnetic button cooperate to abut against each other. The electromagnetic button is used to electrically connect with the control power supply of the reactive power compensator in the substation. An airbag is provided in the fixing groove, and the airbag abuts against the sliding plate.

[0007] Furthermore, an alarm is fixedly installed on the top of the temperature detection element, and the alarm is electrically connected to an electromagnetic button.

[0008] Furthermore, two guide rods are symmetrically fixed in the horizontal direction within the fixing groove. The distance between the two guide rods and the distance between the guide rods and the top and bottom walls of the fixing groove are both less than the minimum diameter of the airbag bulb.

[0009] Furthermore, a limiting rail is provided inside the temperature detection element, the limiting rail is connected to the fixing groove, a limiting component is fixedly installed on the side of the slide plate, and a ball is rotatably provided on one side of the limiting component, the ball being rotatably connected to the limiting rail.

[0010] Furthermore, there are two limiting rails, and the two limiting rails are symmetrically arranged inside the temperature detection element, and the number of limiting rails, limiting elements and ball bearings are all corresponding.

[0011] Furthermore, the limiting member has a fixed cavity and a sliding opening on its interior and one side, respectively. The fixed cavity is connected to the sliding opening, and the ball is rotatably disposed in the fixed cavity and the sliding opening, with a portion located outside the sliding opening.

[0012] Furthermore, positioning plates are fixedly installed at the rear ends of the top and bottom of the temperature detection element, and two bolts are threaded into the front side of the positioning plates. The temperature detection element is installed in the housing of the substation reactive power compensator by means of bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an airbag ball, the airbag ball can expand due to the increase of the surrounding temperature. The gradually expanding airbag ball can push the slide plate to slide in the fixed groove and compress the spring, so that the slide plate drives the striker to abut against the electromagnetic button. Then the electromagnetic button can turn off the control power supply of the substation reactive power compensator, avoiding the problem of short circuit or spontaneous combustion of internal components of the substation reactive power compensator, reducing losses and improving safety.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting an alarm, the alarm sound can remind relevant personnel to carry out timely maintenance and take corresponding measures.

[0015] Compared with the prior art, the beneficial effects of this utility model are: during the sliding process of the skateboard, the skateboard will drive the limiting component and the ball to roll in the limiting rail, which can not only limit the movement direction of the skateboard, but also change the sliding friction of the skateboard in the fixed groove to rolling friction, reducing the friction force, thereby avoiding the problem of the skateboard being unable to slide due to excessive friction between the skateboard and the fixed groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an overheat protection component for a reactive power compensation device in a substation, including a temperature detection element 1. A fixing groove 2 is provided on the front side of the temperature detection element 1. A sliding plate 3 is slidably inserted into the fixing groove 2. A spring 4 is provided between the sliding plate 3 and the inner side wall of the fixing groove 2. A striking pin 5 is also provided on one side of the sliding plate 3. An electromagnetic button 6 is also provided on the inner side wall of the fixing groove 2. The striking pin 5 and the electromagnetic button 6 cooperate to abut against each other. The electromagnetic button 6 is used to electrically connect with the control power supply of the reactive power compensator in the substation. An airbag ball 7 is provided in the fixing groove 2, and the airbag ball 7 abuts against the sliding plate 3.

[0023] In practical implementation, when abnormally high temperatures are generated in the components inside the substation reactive power compensator housing, the temperature is transferred to the airbag ball 7 through the fixed groove 2. This causes the airbag ball 7 to expand, pushing the sliding plate 3 to slide within the fixed groove 2 and compressing the spring 4. The sliding plate 3 then drives the striker 5 to abut against the electromagnetic button 6. Subsequently, the electromagnetic button 6 can shut off the control power supply of the substation reactive power compensator, preventing short circuits or spontaneous combustion of the internal components of the substation reactive power compensator. This reduces losses and improves safety. By setting up an alarm 8, an alarm sound can be heard to remind relevant personnel to conduct timely maintenance and take appropriate measures.

[0024] See Figure 1-4 An alarm 8 is fixedly installed on the top of the temperature detection unit 1, and the alarm 8 is electrically connected to the electromagnetic button 6. By setting the alarm 8, an alarm sound can be heard to remind relevant personnel to carry out timely maintenance and take appropriate measures.

[0025] See Figure 1-4Two guide rods 9 are symmetrically fixed in the horizontal direction within the fixing groove 2. The distance between the two guide rods 9 and the distance between the guide rods 9 and the top and bottom walls of the fixing groove 2 are both less than the minimum diameter of the airbag bulb 7. This prevents the airbag bulb 7 from slipping out of the fixing groove 2, thus ensuring stability during use.

[0026] See Figure 1-4 A limiting rail 10 is provided inside the temperature detection component 1. The limiting rail 10 is connected to the fixed groove 2. A limiting component 11 is fixedly installed on the side of the slide plate 3. A ball bearing 12 is rotatably provided on one side of the limiting component 11. The ball bearing 12 is rotatably connected to the limiting rail 10. A fixed cavity 13 and a sliding opening 14 are respectively provided inside and on one side of the limiting component 11. The fixed cavity 13 is connected to the sliding opening 14. The ball bearing 12 is rotatably provided in the fixed cavity 13 and the sliding opening 14, and part of it is located outside the sliding opening 14.

[0027] In specific implementation, based on the above implementation, during the sliding process of the slide plate 3, the slide plate 3 will drive the limiting member 11 and the ball 12 to roll within the limiting rail 10. This not only limits the movement direction of the slide plate 3, but also changes the sliding friction of the slide plate 3 in the fixed groove 2 to rolling friction, reducing the friction force and thus avoiding the problem of the slide plate 3 being unable to slide due to excessive friction between the fixed groove 2.

[0028] See Figure 1-4 There are two limit rails 10, which are symmetrically arranged inside the temperature detection element 1. The number of limit rails 10, limit elements 11, and balls 12 are all corresponding. This ensures that the top and bottom ends of the slide plate 3 are subjected to balanced forces, preventing the slide plate 3 from tilting during movement.

[0029] See Figure 1-4 The temperature detection component 1 has a positioning plate 15 fixedly installed at the top and bottom rear ends. Two bolts 16 are threaded into the front side of the positioning plate 15. The temperature detection component 1 is installed in the housing of the substation reactive power compensator by means of the bolts 16.

[0030] Working principle: First, the temperature detection component 1 is installed in an area inside the substation reactive power compensator housing that does not obstruct other components via the positioning piece 15 and bolts 16. When the components inside the substation reactive power compensator housing generate abnormally high temperatures, the temperature is transmitted to the airbag ball 7 through the fixing groove 2. This causes the airbag ball 7 to expand, pushing the sliding plate 3 to slide within the fixing groove 2 and compressing the spring 4. This causes the sliding plate 3 to drive the striker 5 to abut against the electromagnetic button 6. Subsequently, the electromagnetic button 6 can shut off the control power of the substation reactive power compensator, preventing short circuits or spontaneous combustion of the internal components of the substation reactive power compensator. This reduces losses and improves safety. By setting an alarm 8, an alarm sound can be heard to remind relevant personnel to conduct timely maintenance and take appropriate measures.

[0031] During the sliding process of the skateboard 3, the skateboard 3 will drive the limiting member 11 and the ball 12 to roll within the limiting rail 10. This not only limits the movement direction of the skateboard 3, but also changes the sliding friction of the skateboard 3 in the fixed groove 2 into rolling friction, reducing the friction force and thus avoiding the problem of the skateboard 3 being unable to slide due to excessive friction between the fixed groove 2.
