[0002] A high-voltage power system data acquisition device is an intelligent electronic device installed at key nodes of a high-voltage transmission and distribution network. Its core task is to collect and record various electrical quantities, status quantities, and environmental quantities during power grid operation in real time, at high speed, and with high precision. It then converts these raw data into digital information and uploads them to the monitoring master station or control system, providing the most basic data support for power grid monitoring, protection, control, and intelligent analysis.

[0003] In the prior art, Chinese Patent Application No. CN202322460006.4 discloses a dust monitor for power data acquisition, including a housing, a rotating disk installed inside the housing, a rotating component installed on one side of the rotating disk, a sliding sleeve installed on the side of the rotating component, a sliding connecting rod installed at one end of the sliding sleeve, a sliding rod penetrating through the sliding connecting rod, the sliding rod being disposed inside the housing, a brush handle installed at one end of the sliding connecting rod, a dust filter installed on one side of the brush handle, the dust filter being disposed inside the housing, and the installation of the dust filter can prevent dust from entering the interior of the monitoring device.

[0004] Based on the above information, it can be seen that existing data acquisition devices need to be connected to power system lines to monitor data such as voltage and current in the power system. However, in actual use, in high-voltage power systems, it is necessary to ensure that the power is disconnected when the device is under maintenance. If the power is not disconnected due to an error, it will cause danger. Utility Model Content

[0005] The purpose of this invention is to provide a data acquisition device for high-voltage power systems to solve the problem of electric shock hazards during maintenance mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a data acquisition device for a high-voltage power system, comprising an acquisition device housing installed inside an electrical cabinet, a maintenance cover mounted on the front side of the acquisition device housing with bolts, a wiring block fixedly mounted on the top of the acquisition device housing, and an installation plate fixedly mounted inside the lower end of the acquisition device housing, a detection instrument mounted on the front side of the installation plate, the detection instrument being connected to a connecting plate via a wiring harness, and a lifting automatic power-off mechanism provided between the connecting plate and the wiring block, which automatically cuts off power when the maintenance cover is opened.

[0007] Preferably, a power transmission cable connected to the power system is installed above the terminal block, and a square-shaped docking groove is formed on the lower surface of the terminal block.

[0008] Preferably, a docking post is fixedly installed at the middle position of the upper surface of the connecting plate, and the docking post and the docking groove are inserted and docked accordingly, and the inside of the docking groove and the outside of the docking post are both made of conductive copper material.

[0009] Preferably, a foldable telescopic insulating sleeve is fixedly installed between the upper surface of the connecting plate and the lower surface of the terminal block.

[0010] Preferably, the automatic power-off mechanism includes guide slide rods fixedly installed on the inner walls of the left and right sides of the collector housing, and the connecting plate and the guide slide rods form a through sliding structure.

[0011] Preferably, the guide slide is provided with a compression spring for pressing the connecting plate to return to its downward position, and a compression rod corresponding to the connecting plate is fixedly installed on the inner side of the inspection cover.

[0012] Preferably, a cooling fan is installed at the lower end of the inside of the collector housing, and ventilation slots are provided on the left and right sides of the collector housing. Furthermore, a heat dissipation fin is fixedly installed on the rear side of the inside of the collector housing, which is in contact with the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the data acquisition device for high-voltage power systems adopts a novel structural design, the specific details of which are as follows: 1. When the device is under maintenance, the automatic power-off mechanism inside the collector housing is used to push the connecting plate downwards, thereby causing the docking post on the upper surface of the connecting plate to disengage from the docking groove below the wiring block, thus achieving automatic power-off and ensuring the safety of the staff during maintenance. Furthermore, the automatic power-off mechanism includes a compression spring, etc. When the inspection cover is opened, the elastic action of the compression spring pushes the connecting plate to slide downward relative to the guide slide rod, thereby achieving the purpose of automatic power-off. When the inspection cover is installed, the compression action of the compression rod (the front end of the compression rod has an inclined structure) is used to lift the connecting plate upward and restore power. Furthermore, an insulating sleeve is installed between the connecting plate and the terminal block to insulate the mating post from the mating groove, ensuring safety.

[0014] 2. The cooling fan rotates to drive airflow, which, together with the ventilation slots, forms a heat dissipation channel. This airflow is used to dissipate heat from the inside of the collector casing. At the same time, the aluminum alloy heat dissipation fins can accelerate the heat conduction speed and achieve better heat dissipation effect. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figures 1-6To achieve automatic power-off, this embodiment provides the following technical solution, specifically: a data acquisition unit housing 1 installed inside an electrical cabinet; a maintenance cover 2 bolted to the front of the data acquisition unit housing 1; a wiring block 3 fixedly installed on the top of the data acquisition unit housing 1; and a mounting plate 5 fixedly installed at the lower end of the inside of the data acquisition unit housing 1. A detection instrument 6 is installed on the front of the mounting plate 5, and the detection instrument 6 is connected to a connecting plate 7 via a wiring harness. A lifting automatic power-off mechanism is provided between the connecting plate 7 and the wiring block 3, automatically cutting off power when the maintenance cover 2 is opened. A power transmission cable 4 connected to the power system is installed above the wiring block 3, and a square-structured connection is provided on the lower surface of the wiring block 3. The connecting plate 7 has a connecting groove 9 and a connecting post 8 fixedly installed at the middle position of the upper surface. The connecting post 8 and the connecting groove 9 are inserted into each other. The inside of the connecting groove 9 and the outside of the connecting post 8 are both made of conductive copper material. A foldable telescopic insulating sleeve 12 is fixedly installed between the upper surface of the connecting plate 7 and the lower surface of the wiring block 3. The automatic power-off mechanism includes guide slide rods 10 fixedly installed on the inner walls of the left and right sides of the collector housing 1. The connecting plate 7 and the guide slide rods 10 form a through sliding structure. A compression spring 11 is provided on the outside of the guide slide rods 10 for pressing the connecting plate 7 to reset downward. A compression rod 13 corresponding to the connecting plate 7 is fixedly installed on the inside of the inspection cover 2.

[0019] When using the device, first, the collector housing 1 is fixedly installed in the electrical cabinet using bolts. Then, the power transmission cable 4, which connects to the power system, is installed into the junction box 3. When the device is working, the current in the power system is transmitted to the junction box 3 through the power transmission cable 4, and then to the connection plate 7 through the junction box 3 (the junction box 3 achieves conductivity through the connection of the docking post 8 and the docking slot 9). Finally, it is transmitted to the detection instrument 6 through the wire, and the detection instrument 6 is used to detect various data in the current (the detection instrument 6 includes an ammeter, voltmeter, and pulse meter, etc.). When it is necessary to inspect the inside of the collector housing 1, first remove the front... The inspection cover 2 on the side is removed, and the compression rod 13 connected to the inspection cover 2 is removed together. The compression rod 13 is released from the compression between the connecting plate 7, and thus the connecting plate 7 is pushed to slide downward relative to the guide slide rod 10 under the elastic compression of the compression spring 11. During the downward sliding of the connecting plate 7, the docking column 8 moves downward synchronously. When the connecting plate 7 slides to the lowest point, the docking column 8 disengages from the docking groove 9 to achieve automatic power cut-off (the external insulating sleeve 12 is used to insulate and protect the disengaged docking column 8 and docking groove 9 to ensure safety). Finally, the device is in a power-off state when the staff performs internal maintenance, which improves the safety during maintenance.

[0020] Example 2: Please refer to Figure 2In order to improve the heat dissipation effect, this embodiment provides the following technical solution, which specifically discloses that: a cooling fan 14 is installed at the lower end of the inside of the collector housing 1, and ventilation slots 15 are opened on the left and right sides of the collector housing 1, and heat dissipation fins 16 that are attached to the mounting plate 5 are fixedly installed on the rear side of the inside of the collector housing 1.

[0021] During the operation of the device, the cooling fan 14 inside the collector housing 1 is turned on. The cooling fan 14 drives the airflow, which, together with the ventilation slot 15 opened on the side, forms a heat dissipation channel, thereby achieving the purpose of heat dissipation inside the collector housing 1. At the same time, the heat dissipation fins 16 attached to the mounting plate 5 are used to accelerate the heat conduction speed and achieve a better heat dissipation effect.
