Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to an electrical contact temperature acquisition device. Background Art

[0002] The development of the power system will develop towards high voltage and large capacity. The transmission capacity of the equipment will continue to increase, and the problem of temperature rise of electrical equipment that troubles the operation of power plants will become prominent. Due to the limited means of fault testing of high-voltage electrical equipment, it is more difficult to find the temperature exceeding the limit point in the switch box and the closed busbar. As the temperature rise time increases, the temperature exceeding the limit will increase the degree of oxidation due to heat, which may cause major accidents such as burning the busbar, contacts, contact damage, and power outages. The temperature measurement of the high-voltage power environment is such a typical measured environment. For such an environment with complex physical structure, scattered distribution of measurement points, and inaccessible or inconvenient access by humans, the commonly used wired data transmission method is limited, making the wireless data collection method more superior. In actual production, sometimes there are many monitoring points that need to detect the temperature, and the temperature monitoring device needs to be disassembled and installed elsewhere in time before continuing the detection. Some existing monitoring devices are connected to multiple temperature sensors through a temperature acquisition and transmission module, so as to monitor the temperature of multiple electrical contacts, and centrally process and package them for unified processing, so as to realize the centralized collection and monitoring of the temperature of electrical contacts.

[0003] Existing electrical contact temperature monitoring equipment is generally fixed and installed by multiple bolts, and its installation method is relatively cumbersome, making it difficult to install it quickly and easily for monitoring the contact temperature, and it is relatively inconvenient to use.

[0004] Therefore, it is necessary to provide a new electrical contact temperature acquisition device to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an electrical contact temperature acquisition device, which solves the problem that the existing electrical contact temperature monitoring equipment is generally fixed and installed by multiple bolts, and its installation method is relatively cumbersome.

[0006] The electrical contact temperature acquisition device provided by the utility model comprises a busbar overlap point and a temperature sensor, wherein the temperature sensor is located on one side of the busbar overlap point, and side seats are fixed on both sides of the temperature sensor, and two mounting shafts are arranged on the side seats at intervals, one end of the mounting shaft is movably connected to the side seat, and the other end of the mounting shaft is fixed with a mounting seat;

[0007] A threaded push rod is provided through the mounting seat, the threaded push rod is threadedly connected to the mounting seat, and a limiting plate is fixed at one end of the threaded push rod close to the busbar overlap point;

[0008] A hexagonal block is fixed to one end of the threaded push rod away from the limiting plate;

[0009] A limit seat is fixed on one side of each of the two side seats, a transmission shaft is movably arranged on the limit seat through a bearing, and both ends of the transmission shaft are connected to a worm;

[0010] A worm wheel is meshedly arranged on one side of the worm, and the worm wheel is mounted on the mounting shaft;

[0011] A handle is fixed on one of the worms.

[0012] In a preferred embodiment, the surface of the limiting plate is roughened.

[0013] In a preferred embodiment, a first stopper is fixed on the side seat, and a second stopper is fixed on the mounting shaft.

[0014] Beneficial effects of the utility model:

[0015] When using this temperature collection device, the staff can turn the handle to move the two mounting seats to a vertical position with the temperature sensor, make one side of the temperature sensor contact the busbar overlap point, and finally use a wrench to turn the hexagonal block to drive the threaded push rod to rotate. The friction between the limit plate and the busbar overlap point can make the temperature sensor stably fixed on the busbar overlap point, which is simple and convenient to operate;

[0016] When the temperature sensor needs to be repaired, use a wrench to reverse the hexagonal block to disengage the limit plate from the busbar overlap point and remove the temperature sensor. After removing the sensor, turn the handle so that the two mounting seats move along the mounting axis to a parallel position with the temperature sensor, reducing its footprint and facilitating transportation.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A three-dimensional view of the main structure of the electrical contact temperature acquisition device provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of shown; Figure 3 This is a plan view of the main structure of the electrical contact temperature acquisition device provided by the utility model.

[0023] In the specific implementation process, Figure 1-Figure 3 As shown, it includes a busbar connection point 1 and a temperature sensor 2. The temperature sensor 2 adopts a wireless temperature sensor of model ATE300, which is powered by CT power supply and has a communication distance of 200m. The temperature data transmitted by the temperature sensor 2 can be received by the ATC series transceiver and forwarded to the display terminal or monitoring center.

[0024] The temperature sensor 2 is located on one side of the busbar lap point 1, and side seats 3 are fixed on both sides of the temperature sensor 2. Two mounting shafts 4 are arranged on the side seats 3 at intervals. One end of the mounting shaft 4 is movably connected to the side seat 3, and the other end of the mounting shaft 4 is fixed with a mounting seat 5. A threaded push rod 6 is penetrated through the mounting seat 5, and the threaded push rod 6 is threadedly connected to the mounting seat 5. A limiting plate 7 is fixed on the end of the threaded push rod 6 close to the busbar lap point 1. The surface of the limiting plate 7 is roughened, and the temperature sensor 2 can be fixed on the busbar lap point 1 by the friction between the limiting plate 7 and the busbar lap point 1.

[0025] A hexagonal block 8 is fixed to one end of the threaded push rod 6 away from the limiting plate 7, so that the staff can use a wrench to rotate the threaded push rod 6 conveniently.

[0026] A limit seat 9 is fixed on one side of the two side seats 3, and a transmission shaft 10 is movably arranged on the limit seat 9 through a bearing. Worms 11 are connected to both ends of the transmission shaft 10. The worm 11 adopts a single-head Archimedean worm, and a worm wheel 12 is meshed on one side of the worm 11. The worm wheel 12 is installed on the mounting shaft 4, and a handle 13 is fixed on one of the worms 11. When the temperature sensor 2 needs to be inspected, the temperature sensor 2 can be removed by reversing the hexagonal block 8 with a wrench to disengage the limit plate 7 from the busbar overlap point 1. After removing the sensor, the handle 13 is turned to make the two mounting seats 5 move along the mounting shaft 4 to be parallel to the temperature sensor 2, thereby reducing the space occupied and facilitating transportation.

[0027] A first stopper 14 is fixed on the side seat 3, and a second stopper 15 is fixed on the mounting shaft 4. When the staff rotates the handle 13, when the first stopper 14 contacts the second stopper 15, it means that the two mounting seats 5 have moved to a vertical state with the temperature sensor 2.

[0028] Working principle of the utility model: When the temperature collection device is used, the staff can rotate the handle 13 to drive the transmission shaft 10 to rotate. Under the transmission action of the two worms 11 and the two worm wheels 12, the two installation shafts 4 rotate at the same time to drive the two installation seats 5 to approach each other until the first stopper 14 contacts the second stopper 15. At this time, the two installation seats 5 move to a vertical posture with the temperature sensor 2;

[0029] Put one side of the temperature sensor 2 in contact with the busbar lap point 1, and finally use a wrench to rotate the hexagonal block 8 to drive the threaded push rod 6 to rotate. When the threaded push rod 6 rotates, the limit plate 7 moves to a position in contact with one side of the busbar lap point 1. Continuing to apply the pre-tightening force can make the limit plate 7 tightly contact with the busbar lap point 1. The friction between the limit plate 7 and the busbar lap point 1 can stably fix the temperature sensor 2 on the busbar lap point 1;

[0030] When the temperature sensor 2 needs to be repaired, the temperature sensor 2 can be removed by using a wrench to reverse the hexagonal block 8 so that the limit plate 7 is separated from the busbar overlap point 1. After removing the sensor, turn the handle 13 so that the two mounting seats 5 move along the mounting axis 4 to a position parallel to the temperature sensor 2, thereby reducing its footprint and facilitating transportation.
