Description

Technical Field

[0001] The invention relates to the technical field related to temperature monitors, and in particular to a center-mounted high-voltage cabinet contact temperature monitor. Background Art

[0002] The center-mounted high-voltage cabinet is also called metal-clad center-mounted removable switchgear. It belongs to the high-voltage power distribution device, which is divided into circuit breaker room, metering room, cable room and main busbar room. The "five protection" functions of electrical operation are realized through the transmission mechanism of the cabinet and the chassis of the circuit breaker trolley. The connection between the circuit breaker and the main circuit adopts the moving and static contact method. The static contact is connected to the main busbar and installed in the insulating box. The moving contact can contact and connect with the static contact after a certain stroke.

[0003] However, in actual use, the high-voltage circuit breaker contacts may heat up due to contact oxidation, dirt, equipment aging, and poor contact between the moving and static contacts. If not discovered and dealt with in time, it may easily cause the equipment to burn out. Therefore, it is of great significance to monitor the temperature of high-voltage circuit breaker contacts, busbars, and high-voltage cable connectors to detect and eliminate thermal fault hazards in advance, which is of great significance to the safe and reliable operation of the power system.

[0004] At present, most of the temperature detection is carried out by installing wireless passive temperature sensors on contacts with power strips, and accurately sensing the temperature of the object by direct contact with the surface of the object being measured. However, in actual use, there are still the following shortcomings:

[0005] First, the power belt may be deformed due to being squeezed by tools such as pliers, shaking during carrying, improper storage, etc., resulting in poor fit between the power belts, which will not only reduce the stability of sensor installation, but also reduce the stability of inductive power collection;

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] Example: Figure 1-4 and Figure 6 As shown, a centrally mounted high-voltage cabinet contact temperature monitor of the present invention comprises a temperature measuring unit 1, which comprises an upper shell 11 and a lower shell 12, wherein an induction power taking module and a temperature measuring module 14 are installed in the upper shell 11, and a mounting through hole 13 is opened on the upper shell 11;

[0051] The conductive unit for contacting the contact surface is composed of a conductive plate 9 installed in the lower housing 12 and a plurality of elastic conductive members 10 installed side by side at the bottom of the conductive plate 9;

[0052] The power-collecting belt 5 can pass through the installation through hole 13 and collect power by induction by cooperating with the induction power-collecting module;

[0053] The alloy bracket 3 connected to the upper shell 11 through the adaptation component is used in conjunction with the power-taking belt 5 to install the temperature measuring unit 1 on the contact;

[0054] The action unit 7 disposed inside the alloy support 3 is used to fix the power-taking belt 5 or to shape the power-taking belt 5;

[0057] The temperature measuring host wirelessly connected to the temperature measuring module 14 is used to receive the electrical signal from the temperature measuring module 14 and display the temperature.

[0058] The sensed temperature signal is converted into an electrical signal by the temperature measuring module 14, and the electrical signal from the temperature measuring module 14 is received by the temperature measuring host. After the temperature measuring host processes and analyzes the electrical signal, it records the data and displays the temperature on a display screen.

[0059] Among them, Figure 3 , Figure 4 and Figure 6As shown, the lifting unit 6 includes a threaded sleeve 61 that penetrates the alloy bracket 3 and a lifting bracket 63 that is arranged on the inner side of the alloy bracket 3 for supporting the control unit 8. The top of the lifting bracket 63 is connected to a threaded adjustment rod 62 that is screwed to the threaded sleeve 61 through a rotating member. An adjusting head 64 is installed on the upper end of the threaded adjustment rod 62. An adjustment hole is opened on the top of the adjusting head 64. The set adjustment hole can be a hole that matches the screwdriver bit. After the screwdriver bit is inserted into the adjustment hole, the screwdriver is rotated to drive the adjusting head 64, and then drive the threaded adjustment rod 62; the threaded adjustment rod 62 is rotated by rotating the adjusting head 64. Since the threaded adjustment rod 62 is threadedly connected to the threaded sleeve 61, the threaded adjustment rod 62 will rotate and move up or down, thereby driving the lifting bracket 63 to achieve height adjustment of the action unit 7 and the control unit 8.

[0060] Among them, Figure 4-9 As shown, the regulating unit 8 includes a guide wheel 81 rotatably connected to the lifting bracket 63 via a rotating rod 86, an adjusting belt 83 guided by the guide wheel 81, a transmission rod 84, an adjusting assembly 85, and a transmission cover 87 arranged on one side of the adjusting assembly 85, both ends of the transmission rod 84 are connected to the transmission cover 87, and the adjusting assembly 85 is composed of a support plate 1 853 connected to the lifting bracket 63 via a connecting screw, a support plate 2 854 located on one side of the support plate 1 853, and two winding rods 851 rotatably arranged on the support plate 1 853, one end of the winding rod 851 is installed with a gear 852, and the other end is connected to the support plate 2 854 through a rotating member. Rotational connection, the support plate 1 853 and the support plate 2 854 are both provided with a central hole capable of accommodating the transmission rod 84 to pass through, and the outer side of the central hole is symmetrically provided with connecting holes that cooperate with the connecting screw, and a positioning cylinder 855 is provided at one end of the connecting hole on the support plate 1 853, and a positioning ring groove is provided at one end of the positioning cylinder 855, and a magnetic ring 856 is installed in the positioning ring groove, and a positioning ring 857 matching the positioning ring groove is provided at one end of the connecting hole on the support plate 2 854, and the positioning ring 857 is made of iron or magnet material, and the positioning ring 857 is attracted by the magnetic ring 856, which can effectively avoid skewing when assembling the support plate 1 853 and the support plate 2 854;

[0061] One end of the transmission cover 87 is rotatably connected to the support plate 853, and the inner side of the transmission cover 87 is provided with an annular inner gear ring 871 meshing with the gear 852. The closed end of the transmission cover 87 is provided with a rotating rod 872 that is coaxial with the transmission cover 87 and rotatably connected to the lifting bracket 63. One end of the rotating rod 872 extends to the outside of the alloy bracket 3 and is installed with a regulating head 82.

[0062] The regulating head 82 is rotated to drive the transmission cover 87 through the rotating rod 872, and the winding rod 851 is driven by the meshing transmission of the annular inner gear ring 871 and the gear 852. The height of the double-tooth support plate 72 is adjusted by releasing the adjustment belt 83 of different lengths, so that the action roller 1 73 and the action roller 2 71 are in a state of alternating heights, forming a shaping channel that can shape the power-collecting belt 5, and the height between the action roller 1 73 and the action roller 2 71 is adjustable, which is suitable for use with power-collecting belts 5 of different thicknesses.

[0063] Among them, Figure 6 As shown, one end of the adjusting belt 83 is connected to the winding rod 851, and the other end is installed with a threaded joint 831. The threaded joint 831 is connected to the threaded blind hole to complete the connection between the adjusting belt 83 and the double-tooth support plate 72. It is easy to disassemble and facilitate the later replacement of the adjusting belt 83 or the action roller group 2.

[0064] Among them, Figure 4 and Figure 5 As shown, the action unit 7 is composed of an action roller group 1 and an action roller group 2. The action roller group 1 includes two three-tooth support plates 74 symmetrically installed at the lower part of the lifting bracket 63 and three action rollers 1 73 installed side by side between the two three-tooth support plates 74. The three-tooth support plates 74 are provided with through holes 741 through which the adjustment belt 83 can pass.

[0065] The second action roller group is composed of two symmetrically arranged double-tooth support plates 72 and two action rollers 71 installed between the double-tooth support plates 72. The action rollers 71 and the action rollers 73 are staggered. The double-tooth support plates 72 are provided with threaded blind holes that are screwed to the threaded joints 831.

[0066] The action unit 7 is driven by the lifting bracket 63 to adjust the height of the action roller 1 73 and the action roller 2 71 parallel to the action roller 1 73, and the power-collecting belt 5 is pressed by lowering the action roller 1 73 and the action roller 2 71 to complete the fixing of the power-collecting belt 5.

[0067] Among them, Figure 11-13 As shown, the elastic conductive member 10 includes a pressure-bearing portion 101 and a connecting portion 103 for connecting to the conductive plate 9. Both ends of the pressure-bearing portion 101 are smoothly connected with sliding portions 102. One end of the two sliding portions 102 is connected to the connecting portion 103 via a folding portion 104. Heat is conducted to the conductive plate 9 via the elastic conductive member 10, and then the temperature is measured by the temperature measuring module 14.

[0068] Specifically, a sliding through hole that slidably cooperates with the sliding portion 102 is opened at the bottom of the lower shell 12 .

[0069] When the temperature measuring unit 1 is installed using the power-taking belt 5, the elastic conductive member 10 is brought into contact with the contact surface, and the pressure-bearing portion 101 is deformed due to the compression of the contact. At the same time, the sliding portion 102 slides along the sliding through hole into the lower shell 12, so that the folding portion 104 is folded due to pressure, and finally the pressure-bearing portion 101 is in full contact with the contact, which can automatically adapt to objects of different shapes and fit more fully with the surface of the object, thereby solving the problem of increased detection error due to insufficient contact.

[0070] Among them, Figure 1 , Figure 2 and Fig.10 As shown, the alloy bracket 3 is provided with a strip through hole 32 that can accommodate the rotation of the rotating rod 872, and baffles 31 are provided on both sides of the alloy bracket 3. A hanging hole 311 is provided on the baffle 31. The strip through hole 32 is conducive to adjusting the height of the control unit 8; the baffle 31 can cover the control unit 8 to improve the overall aesthetics; the hanging hole 311 on the baffle 31 provides a hanging point for the hook 4.

[0071] Specifically, the adaptation component includes a spiral telescopic part 2, both ends of which are provided with a hanging buckle 4 that can cooperate with a hanging hole 311. The spiral telescopic part 2 can be a spiral telescopic rope or a spring. The hanging buckle 4 is used to hang the spiral telescopic part 2 on the alloy bracket 3 and the upper shell 11 to achieve the connection between the alloy bracket 3 and the temperature measuring unit 1, thereby effectively preventing the alloy bracket 3 from being lost.

[0072] Specifically, the upper shell 11 is provided with a second hanging hole matched with the hanging buckle 4 , and the second hanging hole provides a hanging point for the hanging buckle 4 .

[0073] During operation, by rotating the regulating head 82, the rotating rod 872 drives the transmission cover 87, and by means of the meshing transmission of the annular inner gear ring 871 and the gear 852, the winding rod 851 is driven to adjust the height of the second action roller 71, so that the first action roller 73 and the second action roller 71 are in a state of staggered height, forming a shaping channel for shaping the power-taking belt 5, so that the power-taking belt 5 that needs to be shaped passes between the first action roller 73 and the second action roller 71, and the shaping is achieved by squeezing the power-taking belt 5 by the first action roller 73 and the second action roller 71. After the shaping is completed, the regulating unit is used to adjust the height of the second action roller 71. 8 Adjust the second action roller 71 so that the second action roller 71 and the first action roller 73 are in the same horizontal plane, then take two power-collecting belts 5 and pass them through the alloy bracket 3. After folding the power-collecting belt 5 in the middle, the four-layer power-collecting belt 5 passes through the buffer gasket and the mounting through hole 13, and the temperature measuring unit 1 is placed on the contact. The power-collecting belt 5 then passes through the alloy bracket 3. After being tightened, the elastic conductive member 10 can fully contact the contact surface. Use the lifting unit 6 to adjust the height of the action unit 7, and use the action roller 1 73 and the second action roller 71 to press the power-collecting belt 5, and then cut off the excess power-collecting belt 5.
