Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature measurement technology for high-voltage power equipment, and specifically to a high-voltage auxiliary measuring insulating clip. Background Technology
[0002] In high-voltage power operations, workers often need to perform various operations, such as temperature measurement, on live conductors, requiring the use of insulating clamps to hold temperature sensors to the equipment surface. In this process, the stability and safety of the insulating clamps are crucial tools. While some clamping tools exist on the market, most are made of metal, which can create a potential difference with the live conductor under high voltage, posing a risk of discharge. Some clamping tools made of insulating materials suffer from insufficient mechanical strength and inconvenience in operation. Especially during operation, clamp misalignment can lead to insufficient clamping force, causing the sensor to slip or make poor contact, affecting measurement efficiency and quality. This is particularly true for temperature measurement of large reactor coils. When the coil is energized, it is necessary to measure the internal temperature of different parts of the coil, requiring insulating clamps with sufficient clamping force to prevent misalignment from affecting the contact between the temperature sensor and the coil. However, metal materials cannot be used, and there is no excellent solution to this problem in current technology. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-voltage auxiliary measurement insulating clamp that can firmly hold the temperature sensor and ensure the temperature measurement effect.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A high-voltage auxiliary measuring insulating clamp is made entirely of insulating material and includes a clamp body and a clamping part. The clamp body consists of a first lever arm and a second lever arm, both of which are S-shaped and intersect each other. The first lever arm and the second lever arm are connected at the intersection point by a pivot. The clamping part is located at the head of the clamp body and consists of a first clamping plate and a second clamping plate. The first clamping plate is connected to the first lever arm by a pivot, and the second clamping plate is connected to the second lever arm by a pivot.
[0006] In this utility model, preferably, the outer sides of the tails of both the first lever arm and the second lever arm are provided with grooves, and the grooves of the first lever arm and the second lever arm are positioned corresponding to each other.
[0007] In this invention, preferably, both the first clip and the second clip are made of silicone.
[0008] In this invention, preferably, the pivot between the first lever arm and the second lever arm is installed using fiberglass bolts.
[0009] In this utility model, preferably, the pivot between the first clamping plate and the first lever arm is installed by fiberglass bolts, and the pivot between the second clamping plate and the second lever arm is installed by fiberglass bolts.
[0010] In this invention, preferably, the clamping body is made of any one of the following materials: fiberglass, polyurethane, or fiberglass resin board.
[0011] In this invention, preferably, both the front sides of the first clip and the front sides of the second clip are provided with grooves to accommodate the temperature sensor.
[0012] In this utility model, preferably, a notch is provided at the part where the head of the first lever arm contacts the first clamping piece to increase the rotation range of the first clamping piece; a notch is provided at the part where the head of the second lever arm contacts the second clamping piece to increase the rotation range of the second clamping piece.
[0013] In this invention, preferably, both the first clip and the second clip are rectangular in shape.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The high-voltage auxiliary measuring insulating clamp of this invention ensures that the clamping part remains completely in contact with the surface of the reactor coil even when tilted, preventing the measuring sensor from slipping or making poor contact. This allows monitoring of the reactor temperature to continue, ensuring effective temperature measurement. A groove is provided at the tail of the high-voltage auxiliary measuring insulating clamp to prevent the elastic ring from sliding freely, ensuring sufficient elastic force is applied to the clamp. Both the first and second clamping pieces are made of silicone, providing excellent insulation and increasing friction to enhance the clamp's cushioning effect. The rotating shaft is installed using fiberglass bolts, ensuring insulation and good mechanical properties at both points. The clamping body is made of any one of fiberglass, polyurethane, or fiberglass resin board, ensuring good insulation and high-temperature resistance. Grooves are provided on the front of both the first and second clamping plates to accommodate temperature sensors, resulting in better clamping and less likelihood of the temperature sensors loosening. Both the first and second clamping plates are rectangular in shape, making them easier to process and reducing raw material waste, and providing greater stability when clamped to the reactor surface. Notches are provided at the contact points between the head of the first lever arm and the first clamping plate, and at the contact points between the head of the second lever arm and the second clamping plate, which helps to better maintain the fit between the first and second clamping plates and the reactor surface, accommodating greater tilting of the first and second lever arms.

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] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] Please see Figure 1 A preferred embodiment of this utility model provides a high-voltage auxiliary measuring insulating clamp, made entirely of insulating material, comprising a clamp body and a clamping part. The clamp body consists of a first lever arm 1 and a second lever arm 2, both of which are "S"-shaped. This "S" shape is not exactly the same as the letter S, but rather resembles... Figure 1The diagram shows a shape with parallel ends and a curved middle, allowing two such shapes to intersect to form a clamp or pincer shape. The first lever arm 1 intersects with the second lever arm 2, and the first lever arm 1 and the second lever arm 2 are connected at the intersection by a pivot, thus forming the basic shape of a clamp, as shown. Figure 1 As shown, the rotating shaft 3 of the clamp body is the rotating shaft mentioned here. The intersection point of the first lever arm 1 and the second lever arm 2 can be the midpoint, or it can be close to one end of the clamp body as needed, thus forming a force-saving lever or a force-consuming lever. The clamping part is located at the head of the clamp body, or rather, whichever end of the clamp body the clamping part is located at is defined as the head, and the other end is defined as the tail. The clamping part consists of a first clamping piece 7 and a second clamping piece 4. The first clamping piece 7 is connected to the first lever arm 1 through the rotating shaft, and the second clamping piece 4 is connected to the second lever arm 2 through the rotating shaft, as shown below. Figure 1 As shown, the rotating shaft 5 of the clamping part is the rotating shaft mentioned here.
[0024] like Figure 2 and Figure 3 As shown, when using this high-voltage auxiliary measuring insulating clamp, the temperature sensor 6 is attached to the surface of the reactor coil. Then, the clamping part of the high-voltage auxiliary measuring insulating clamp is used to clamp the temperature sensor 6 onto the surface of the reactor coil. An elastic ring (not shown in the attached figure) is placed on the tail of the clamp body. The elasticity of the elastic ring is used to clamp the temperature sensor 6 tightly with the high-voltage auxiliary measuring insulating clamp. Then, the reactor can be run, and the temperature of the reactor can be monitored using the temperature sensor 6. During the measurement process, the clamp may become misaligned due to operational or environmental factors. With ordinary clamps, misalignment leads to a lack of contact between the clamp and the reactor coil, causing the temperature sensor 6 to loosen and resulting in poor contact or even detachment. Due to the high-voltage environment on the reactor surface, technicians cannot directly re-clamp the clamp; they must first disconnect the power, affecting the measurement process. However, with the high-voltage auxiliary measuring insulating clamp of this invention, when misalignment occurs, the clamping part and clamp body are connected by a rotating shaft. The misalignment is not directly transmitted to the clamping part but instead causes the clamp body to rotate around the shaft. The clamping part still tightly holds the temperature sensor 6, ensuring complete contact with the reactor coil surface. Therefore, the sensor will not slip or experience poor contact, allowing the monitoring of the reactor temperature to continue, thus ensuring the effectiveness of the temperature measurement.
[0025] It should be noted that elastic bands are elastic ring-shaped components made of various insulating and high-temperature resistant materials, such as rubber bands made of heat-resistant silicone rubber.
[0026] Because the elastic ring may slide at the tail of the high-voltage auxiliary measuring insulating clamp, resulting in a decrease in the applied elastic force and the clamp failing to clamp tightly, in a preferred embodiment of this utility model, grooves are provided on the outer sides of the tails of both the first lever arm 1 and the second lever arm 2, with the grooves of the first lever arm 1 and the second lever arm 2 corresponding in position. Figure 1 and Figure 2 As shown. By fitting the elastic ring into the groove at the tail of the first lever arm 1 and the second lever arm 2, the elastic ring is locked in place and will not slide freely, thus ensuring that sufficient elastic force is applied to the high-voltage auxiliary measuring insulating clamp.
[0027] In a preferred embodiment of this invention, both the first clip 7 and the second clip 4 are made of silicone. Silicone has good insulation properties, can increase friction, and is relatively soft, thus enhancing the cushioning effect of the clip.
[0028] In a preferred embodiment of this invention, the pivot between the first lever arm 1 and the second lever arm 2 is installed using fiberglass bolts. The pivot between the first clamp 7 and the first lever arm 1 is also installed using fiberglass bolts, as is the pivot between the second clamp 4 and the second lever arm 2. The fiberglass bolts possess excellent insulation and strength, ensuring both pivots maintain good insulation and mechanical properties.
[0029] In a preferred embodiment of this invention, the clamp is made of any one of the following materials: fiberglass, polyurethane, or fiberglass resin board. Fiberglass, polyurethane, and fiberglass resin board materials have good insulation properties and can withstand high temperatures, making them suitable for applications involving surface temperature measurement of reactors.
[0030] In a preferred embodiment of this invention, grooves are provided on the front sides of both the first clip 7 and the second clip 4 to accommodate the temperature sensor 6. Figure 2 As shown. The temperature sensor 6 can be an insulated sensor such as an optical fiber, and has a certain protrusion. It can usually be clamped securely by the first clamping piece 7 and the second clamping piece 4 without loosening. However, for better clamping, grooves can be made on the front of the first clamping piece 7 and the second clamping piece 4. The temperature sensor 6 is placed in the groove, making the front of the first clamping piece 7 and the second clamping piece 4 basically flat. This results in a better clamping effect and makes the temperature sensor 6 less prone to loosening. Furthermore, the first clamping piece 7 and the second clamping piece 4 are both rectangular in shape. This has the advantage of being easier to process and shape, reducing raw material waste, and the rectangular edges have more contact with the surface of the reactor, making the first clamping piece 7 and the second clamping piece 4 more stable when clamped on the reactor surface.
[0031] In a preferred embodiment of this invention, a notch is provided at the point where the head of the first lever arm 1 contacts the first clamping piece 7, to increase the rotation range of the first clamping piece 7, such as... Figure 1 and Figure 2 As shown, a notch is provided at the point where the head of the second lever arm 2 contacts the second clamping plate 4 to increase the rotation range of the second clamping plate 4. Increasing the rotation range of the first clamping plate 7 and the second clamping plate 4 allows for better contact between the first clamping plate 7 and the second clamping plate 4 and the reactor surface, accommodating greater tilting of the first lever arm 1 and the second lever arm 2.
[0032] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
