Description

Technical Field

[0001] The present invention relates to the technical field of live power extraction in an electric power system, and in particular to a live power extraction temperature measuring device and method. Background Art

[0002] In recent years, the power Internet of Things has been developing vigorously in order to build a world-class smart grid. In the field of power distribution, medium-voltage automation construction has taken shape, but low-voltage distribution automation is still in its infancy. In view of the massive stock market, a large number of intelligent devices need to empower traditional non-intelligent devices, such as station buildings, distribution transformers, low-voltage switches, branch boxes, meter boxes, etc.

[0003] For the front-line teams, the installation of smart devices with live power is undoubtedly a major benefit, which can avoid the stress of power outages. For a long time, people have been studying live power installation and live power extraction, but ultimately, due to the excessive complexity of the on-site scenes, it is difficult to achieve universal application, and live power extraction is not safe and convenient enough, so it has not been truly promoted for practical use.

[0004] It can be seen that providing a live power extraction device that is safe and convenient to use is an issue that urgently needs to be solved in the art. Summary of the invention

[0005] The main purpose of the present invention is to overcome the shortcomings of the prior art and provide a live electric temperature measurement device and method which is simple and convenient to install, safe, highly reliable, has a wide range of applications, and is easy to promote and apply on a large scale.

[0006] The present invention adopts the following technical solution:

[0007] A live power-taking and temperature-measuring device comprises an openable clamp body, a power-taking sheet and a temperature-measuring sheet. The clamp body comprises two movable clamps arranged opposite to each other. The power-taking sheet and the temperature-measuring sheet are respectively mounted on the inner sides of the two movable clamps. The two movable clamps are relatively opened and closed to clamp the exposed conductor of the power equipment between the power-taking sheet and the temperature-measuring sheet and to make the exposed conductor of the power equipment electrically conductively connected to the conductive sheet and the temperature-measuring sheet respectively. The power-taking sheet is made of conductive material and is provided with a power-taking hole for connecting the power-taking wire. The temperature-measuring sheet is made of conductive and heat-conductive material and is provided with a temperature-measuring resistor mounting clamp for mounting a temperature-measuring resistor.

[0008] Furthermore, the movable clip is made of insulating material.

[0009] Furthermore, the two movable clamps are respectively provided with a plurality of positioning posts, and the power taking piece and the temperature measuring piece are respectively provided with a plurality of positioning countersunk holes matching with the positioning posts, and the power taking piece and the temperature measuring piece are fixedly mounted on the movable clamps by the positioning countersunk holes matching with the positioning posts.

[0010] Furthermore, the two movable clamping pieces of the clamp body are hingedly assembled, and a torsion spring is arranged between the two movable clamping pieces.

[0011] Furthermore, the two movable clips are respectively provided with slots for installing torsion springs, and the torsion springs are installed in the slots by means of front and rear limiting snap-fitting.

[0012] Furthermore, the movable clamp is provided with a wire hole for leading out the wires.

[0013] Furthermore, a temperature measuring plate buckle is provided on the movable clamp, and the temperature measuring resistor installation clip of the temperature measuring plate is positioned and clamped at the temperature measuring plate buckle.

[0014] Furthermore, the crimping surfaces of the power taking piece and the temperature measuring piece both form a bending structure, and the angle of the bending structure is 120°±10°, which is used for crimping with the exposed conductor of the nut-shaped power equipment.

[0015] Furthermore, both sides of the power taking piece and the temperature measuring piece extend away from the crimping surface to form reinforced bending edges.

[0016] A method for measuring temperature with power supply based on the above-mentioned device for measuring temperature with power supply comprises the following steps:

[0017] Step 1, install the temperature measuring resistor on the temperature measuring resistor mounting clamp of the temperature measuring piece through thermal conductive glue, and connect the power taking wire to the power taking hole of the power taking piece;

[0018] Step 2: operate the fixture body to open the two movable clamps relative to each other, clamp the live power supply and temperature measurement device on the exposed conductor of the power equipment, release the fixture body, make the power supply plate and the temperature measurement plate both conduction-connected with the exposed conductor of the power equipment, and then realize the live power supply and temperature measurement operation;

[0019] Step 3, after the operation is completed, operate the clamp body to open the two movable clamps relative to each other, and then remove the live power temperature measuring device from the exposed conductor of the power equipment.

[0020] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0021] First, the present invention can realize power supply and temperature measurement by installing the power supply plate and the temperature measuring plate on the inside of the clamp body and clamping it on the exposed conductor of the power equipment. The clamp method is extremely easy to install, safe and convenient to use, with a wide range of applications, and easy to promote and apply on a large scale.

[0022] Second, the clamp body of the present invention is made of insulating material as a whole, and the power supply sheet and the temperature measuring sheet are installed inside the clamp body, which is highly safe and does not cause any damage to the exposed conductors of the original power equipment.

[0023] Third, since bolts and nuts are used in conventional power connections, whether cable connections or copper busbar connections, the crimping surfaces of the power-taking piece and the temperature-measuring piece of the present invention form a bending structure that matches the shape of the nut and can be directly fixed on the nut, thereby increasing the reliability of the conductive connection and making live power taking and temperature measurement safe and convenient.

[0024] Fourth, the power supply sheet and the temperature measuring sheet are installed on the fixture body through the positioning columns and the positioning countersunk holes. The positioning countersunk hole structure ensures that the hot melt adhesive will not protrude above the surface of the power supply sheet and the temperature measuring sheet after being melted and fixed, thereby ensuring reliable conductive contact between the power supply sheet and the temperature measuring sheet and the exposed conductors of the power equipment, thereby improving the reliability of power supply and temperature measurement.

[0025] Fifth, the torsion spring is installed between the two movable clips by means of front and rear limiters, without the need for metal shaft connection, which can effectively reduce safety hazards during the use of the live power temperature measuring device and improve safety of use.

[0032] The present invention is further described below through specific implementation modes.

[0033] Example 1

[0034] Reference Figures 1 to 5The present invention discloses a live power-taking and temperature-measuring device, comprising an openable clamp body, a power-taking sheet 1 and a temperature-measuring sheet 2.

[0035] The clamp body includes a left movable clamp 3 and a right movable clamp 4 that are relatively arranged and a torsion spring 5. A disk 6 is provided in the middle of the left movable clamp 3 and the right movable clamp 4, and an assembly hole 7 is opened on the disk 6. The left movable clamp 3 and the right movable clamp 4 are hingedly assembled by the mounting pins 8 on both sides and the assembly hole 7. The left movable clamp 3 and the right movable clamp 4 are made of insulating material, specifically ABS flame-retardant material. The torsion spring 5 is installed between the left movable clamp 3 and the right movable clamp 4. The left movable clamp 3 and the right movable clamp 4 are respectively provided with a slot composed of a front reinforcing rib 9 and a rear reinforcing rib 10. The torsion spring 5 is installed in the slot by a front and rear limiting method, without a metal shaft. The torsion spring 5 is used to clamp the power extraction plate 1 and the temperature measuring plate 2 to the exposed conductor of the power equipment through the action of torque. In this embodiment, the exposed conductor of the power equipment is a nut 11.

[0036] The power-collecting sheet 1 and the temperature-measuring sheet 2 are respectively installed on the inner sides of the right movable clamp 4 and the left movable clamp 3. The left movable clamp 3 and the right movable clamp 4 are relatively opened and closed to clamp the exposed conductor of the power equipment between the power-collecting sheet 1 and the temperature-measuring sheet 2 and to make the exposed conductor of the power equipment electrically connected to the conductive sheet 1 and the temperature-measuring sheet 2 respectively. The power-collecting sheet 1 is made of conductive material, specifically copper, and the power-collecting sheet 1 is formed with a power-collecting hole 12 for connecting the power-collecting wire. The temperature-measuring sheet 2 is made of conductive and heat-conductive material, specifically silver, and the temperature-measuring sheet 2 is formed with a temperature-measuring resistor mounting clamp 13 for mounting a temperature-measuring resistor, and the temperature-measuring resistor mounting clamp 13 is an open semicircular ring structure.

[0037] Two positioning posts 14 are respectively provided on the left movable clamp 3 and the right movable clamp 4, and two positioning countersunk holes 15 matching with the positioning posts 14 are respectively provided on the power taking piece 1 and the temperature measuring piece 2. The power taking piece 1 and the temperature measuring piece 2 are fixedly mounted on the right movable clamp 4 and the left movable clamp 2 through the positioning countersunk holes 15 matching with the positioning posts 14. The positioning posts 14 are hot melt posts. By setting the positioning countersunk holes 15, the hot melt adhesive will not be higher than the surface of the power taking piece 1 and the temperature measuring piece 2 after melting and fixing, which can ensure that the power taking piece 1, the temperature measuring piece 2 and the nut 11 have good conductive contact. A wire hole 16 for leading out the power taking wire is provided on the right movable clamp 4. A temperature measuring piece buckle 17 is provided on the left movable clamp 3, and the temperature measuring resistor mounting clip 13 of the temperature measuring piece 2 is positioned and clamped at the temperature measuring piece buckle 17. The crimping surfaces of the power-collecting sheet 1 and the temperature-measuring sheet 2 are both formed with a bending structure, and the angle of the bending structure is 120°, which is used to cooperate with the nut 11 for crimping. The left movable clamp 3 and the right movable clamp 4 are respectively connected to the webbed structure 18 at the bending part of one side, which can increase the strength of the left movable clamp 3 and the right movable clamp 4, and can limit the nut 11 clamped therebetween. Both sides of the power-collecting sheet 1 and the temperature-measuring sheet 2 extend away from the crimping surface to form a reinforced bending edge 19.

[0038] A method for measuring temperature with power supply based on the above-mentioned device for measuring temperature with power supply comprises the following steps:

[0039] Step 1, install the temperature measuring resistor on the temperature measuring resistor mounting clip 13 of the temperature measuring piece 2 through the thermal conductive adhesive, and connect the power taking wire to the power taking hole 12 of the power taking piece 1;

[0040] Step 2, operate the fixture body to open the left movable clamp 3 and the right movable clamp 4 relatively, clamp the live power supply and temperature measurement device on the nut 11, release the fixture body, make the power supply sheet 1 and the temperature measurement sheet 2 both conduction-connected with the nut 11, and then realize the live power supply and temperature measurement operation;

[0041] Step 3, after the operation is completed, operate the clamp body to open the left movable clamp 3 and the right movable clamp 4 relatively, and then the live electrical temperature measuring device can be removed from the nut 11.

[0042] Example 2

[0043] The difference between this embodiment and the first embodiment is that the crimping surfaces of the power taking piece 1 and the temperature measuring piece 2 form an arc-shaped structure for clamping with the exposed conductor bolts of the power equipment.

[0044] The above are only two specific implementations of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
