Description

Technical Field

[0001] This utility model relates to the technical field of partial discharge monitoring equipment for switchgear, and in particular to a TEV-type partial discharge monitoring device for switchgear. Background Technology

[0002] The TEV-type switchgear partial discharge monitoring device is a device used to monitor partial discharge in switchgear, employing transient voltage-to-ground detection technology. This device mainly consists of sensors, acquisition units, and monitoring units, and can monitor the partial discharge status of the switchgear in real time during operation.

[0003] Currently, some TEV switch cabinet partial discharge monitoring devices have connection ports on one side wall of the housing for connecting power supplies, data cables, etc. However, these interfaces are often exposed to the air, and dust will accumulate over time. If they are not cleaned for a long time, dust will be brought into the interface when plugging and unplugging data cables. This dust will fill the gaps in the interface, increase the contact resistance, and cause poor current transmission. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a TEV-type switchgear partial discharge monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The TEV type switchgear partial discharge monitoring device includes a TEV type switchgear partial discharge monitoring box body. The TEV type switchgear partial discharge monitoring box body includes a shell. A first connecting line and a second connecting line are inserted on one side wall of the shell. A dustproof mechanism is provided on the side wall of the shell where the first connecting line and the second connecting line are inserted. A limit plate is fixedly connected to the adjacent side wall of the shell. The limit plate is installed on the mounting plate.

[0007] The dustproof mechanism includes a dustproof cover, which is installed on one side wall of the housing. A dustproof plate is vertically inserted into the dustproof cover, and a cover plate is horizontally installed on the top of the dustproof cover.

[0008] The dust cover has symmetrical slots, the dust cover plate is vertically installed in the slots, the top of the dust cover has symmetrical mounting blocks, the inner wall of the mounting blocks is fitted with rubber pads, and the cover plate is horizontally inserted into the gap between the two mounting blocks.

[0009] Furthermore, in a preferred configuration, the rubber pad is in contact with the cover plate.

[0010] Furthermore, a preferred structure is that a plurality of protrusions are evenly arranged in the transverse direction on the upper surface of the cover plate.

[0011] In addition, a preferred structure is that the dustproof plate has symmetrically opened installation openings at the top and bottom, and insert plates are symmetrically arranged on both sides of the dustproof plate, with the insert plates vertically inserted into the installation groove.

[0012] Furthermore, in a preferred configuration, the insert plate is vertically connected to a first clamping plate above the lower mounting port, and a second clamping plate is vertically connected to the lower mounting port below the lower mounting port. The first connecting line is disposed on the first clamping plate, and the second connecting line is disposed on the second clamping plate.

[0013] In addition, a preferred structure is that a mounting groove is vertically formed on the upper surface of the mounting plate, and a limiting insert is inserted into the mounting groove.

[0014] The beneficial effects of this utility model are as follows: By setting a dustproof mechanism on one side of the TEV switchgear partial discharge monitoring box, the dust cover and dustproof plate can effectively prevent dust from falling into the interface when the first connecting line and the second connecting line are connected to the housing. This ensures that the interface of the TEV switchgear partial discharge monitoring device will not be affected by dust. The dustproof mechanism effectively plays a dustproof role and can prevent dust from falling into the interface. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-8 The TEV-type switchgear partial discharge monitoring device includes a TEV-type switchgear partial discharge monitoring box body 01. The TEV-type switchgear partial discharge monitoring box body 01 includes a housing 1. A first connecting line 2 and a second connecting line 3 are inserted on one side wall of the housing 1. A dustproof mechanism 02 is provided on the side wall of the housing 1 where the first connecting line 2 and the second connecting line 3 are inserted. A limit plate 4 is fixedly connected to the adjacent side wall of the housing 1. The limit plate 4 is installed on the mounting plate 5. The dustproof mechanism 02 can play a good dustproof role.

[0026] Furthermore, the dustproof mechanism 02 includes a dustproof cover 6, which is installed on one side wall of the housing 1. A dustproof plate 7 is vertically inserted into the dustproof cover 6, and a cover plate 8 is horizontally installed on the top of the dustproof cover 6. The cover plate 8 serves to restrict the movement of the dustproof plate 7.

[0027] In addition, the dust cover 6 has symmetrical slots 61, the dust cover 7 is vertically installed in the slots 61, the top of the dust cover 6 has symmetrical mounting blocks 62, the inner wall of the mounting blocks 62 is fitted with rubber pads 63, the cover plate 8 is horizontally inserted in the gap between the two mounting blocks 62, the rubber pads 63 are in contact with the cover plate 8, the rubber pads 63 can increase damping, thereby preventing the cover plate 8 from falling off easily.

[0028] Among them, multiple protrusions 81 are evenly arranged in the transverse direction on the upper surface of the cover plate 8, and the protrusions 81 make it easy for the operator to pull out the cover plate 8 with their fingers.

[0029] Furthermore, the dustproof plate 7 has symmetrically opened installation openings 71 at the top and bottom, and symmetrically arranged insert plates 74 on both sides of the dustproof plate 7. The insert plates 74 are vertically inserted into the installation groove 51, and the installation groove 51 serves to install the dustproof plate 7.

[0030] Meanwhile, the insert plate 74 is vertically connected to the first clamping plate 72 above the lower mounting port 71, and the second clamping plate 73 is vertically connected to the lower mounting port 71. The first connecting line 2 is set on the first clamping plate 72, and the second connecting line 3 is set on the second clamping plate 73. The first clamping plate 72 and the second clamping plate 73 facilitate clamping the first connecting line 2 and the second connecting line 3.

[0031] The mounting plate 5 has a vertically formed mounting groove 51 on its upper surface. The limiting plate 4 is inserted into the mounting groove 51, which facilitates the installation of the housing 1.

[0032] In this embodiment, when installing the TEV type switch cabinet partial discharge monitoring box body 01, the mounting plate 5 is installed on the switch cabinet. When installing the housing 1, it is only necessary to insert the limit plate 4 into the mounting groove 51. After the limit plate 4 is inserted into the mounting groove 51, the housing 1 will not easily fall off. Then, the dust cover 7 is installed on the dust cover 6 at the interface where the first connecting line 2 and the second connecting line 3 need to be connected.

[0033] When installing the dust cover 7, insert the insert plate 74 into the slot 61. After installing the insert plate 74, insert the cover plate 8 horizontally between the mounting blocks 62. The rubber pad 63 presses the cover plate 8 so that the cover plate 8 will not easily fall out between the mounting blocks 62. The operator can insert the first connecting wire 2 and the second connecting wire 3 from the mounting port 71 into the interface of the TEV switch cabinet partial discharge monitoring box body 01. In this way, during daily use, the dust cover 6 and the dust cover 7 can prevent dust from falling into the interface where the first connecting wire 2 and the second connecting wire 3 are connected.

[0034] In this utility model, by setting a dustproof mechanism 02 on one side of the TEV switch cabinet partial discharge monitoring box body 01, when the first connecting line 2 and the second connecting line 3 are connected to the housing 1, the dust cover 6 and the dustproof plate 7 can effectively prevent dust from falling into their interface. This ensures that the interface of the TEV switch cabinet partial discharge monitoring device will not be affected by dust. The dustproof mechanism 02 effectively plays a dustproof role and can prevent dust from falling into the interface.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
