Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrical equipment, and particularly relates to a temperature measuring sensor for a moving contact of a power cabinet. Background Art
[0002] In a power cabinet, the moving contact often has a phenomenon of high temperature heating. Prolonged high temperature heating often causes power accidents and significant losses. Therefore, temperature monitoring can be carried out at the moving contact to give an early warning, and the heating device can be replaced during power maintenance, thereby avoiding power accidents.
[0003] Currently, the solutions for temperature monitoring of moving contacts include using a structural member screw pre-tightening method to clamp the moving contact, and using RFID radio frequency identification technology, combined with sensor technology and a temperature measuring chip, to achieve temperature measurement of the moving contact.
[0004] When the old product is in use, when the moving contact trolley structure is closed, due to the special structural shape of the contact cabinet, some contacts will undergo structural deformation and swelling, resulting in sensor detachment, inaccurate temperature measurement, or even direct damage to the sensor when the trolley is closed, thereby reducing the working efficiency of the user and even causing power accidents. The solutions for temperature monitoring of moving contacts include using a structural member screw pre-tightening method to clamp the moving contact, and using RFID radio frequency identification technology, combined with sensor technology and a temperature measuring chip, to achieve temperature measurement of the moving contact. Other defects include that due to the special metal structure of the moving contact, internal heat and cold alternation, and periodic frequency vibration, long-term operation will cause a series of problems such as elastic sheet aging and fracture, weakened clamping force, and sensor shaking, resulting in sensor detachment or inaccurate temperature measurement, thereby causing power accidents.

[0057] To better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:
[0058] Embodiment 1. A temperature measuring sensor for a moving contact of a power cabinet, comprising a mounting base 1, a mounting plate 2, a mounting plate connecting member 3, a cover plate 4 and a cover plate connecting member 5.
[0059] The mounting base 1 includes a connected mounting bottom wall 11 and two symmetrically arranged mounting side walls 12 located on both sides of the mounting bottom wall rod 11; one mounting base connection hole 13 is provided on each of the two mounting side walls 12, and the two mounting base connection holes 13 are symmetrically distributed.
[0060] The mounting plate 2 includes an integrally formed first mounting base plate 21 and a second mounting base plate 22, and the size of the first mounting base plate 21 is smaller than that of the second mounting base plate 22, and the two form an inverted T-shaped structure.
[0061] The cover plate 4 is provided with a cover plate connection hole 41, and the outer side surface of the cover plate 4 is convexly formed into a curved surface 42.
[0062] The first connection hole 23 and the mounting base connection hole 13 are detachably connected through the mounting plate connecting member 3, so as to fixedly connect the mounting base 1 and the first mounting base plate 21 together;
[0063] The second connection hole 24 and the cover plate connection hole 41 are detachably connected through the cover plate connecting member 5, so as to cover and connect the cover plate 4 on the second mounting base plate 22, and a storage cavity for placing the temperature measuring device is formed between the cover plate 4 and the mounting plate 2.
[0064] When the ordinary sensor closes the switch under the condition that the moving contact in the power cabinet works for a long time, due to its unique structural shape, some contacts will undergo structural deformation and swelling, resulting in problems such as the sensor falling off, inaccurate temperature measurement, or even direct damage to the sensor when the trolley closes the switch.
[0065] When the temperature measurement sensor of the present utility model is assembled with the moving contact body, the mounting seat 1 is clamped on one of the metal contact pieces of the moving contact from the inside to the outside in the radial direction. Then, the cover plate 4 is covered and connected to the second mounting bottom plate 22 through the cover plate connecting piece 5, and the temperature measurement device is placed in the storage cavity between the cover plate 4 and the mounting plate 2 to realize the installation of the temperature measurement device. Based on the limitation of the mounting bottom wall 11 and the connection of the mounting plate connecting piece 3, the temperature measurement device can be stably connected to the moving contact without falling off. The present utility model has made corresponding adjustments to the connection points of the mounting seat 1, the mounting plate 2, and the cover plate 4. By dividing the mounting plate 2 into two parts and connecting them to the mounting seat 1 and the cover plate 4 respectively, the connection points are separated, thereby reducing the influence of vibration on the temperature measurement device and avoiding the occurrence of situations such as the sensor falling off or inaccurate temperature measurement. Moreover, the present utility model can be applied to moving contacts of different models.
