A power distribution maintenance protection device

Abstract

This utility model relates to the field of power distribution maintenance technology, specifically a power distribution maintenance protection device, including a carrying case body and a connecting assembly, the connecting assembly including a connecting frame. This power distribution maintenance protection device, by installing the connecting assembly, allows for connection of lines between the maintenance device and the protection device. Pulling the lifting blocks on both sides of the connecting frame causes the limiting block to move the connecting plate two upwards, simultaneously compressing the connecting spring. At this time, the lines can be passed sequentially through the wire holes and placed in the cable management groove one. Then, releasing the lifting blocks on both sides allows the connecting plate two and the cable management groove two to move downwards under the force of the connecting spring, thus clamping and fixing the lines. This not only prevents the lines from loosening or tangling but also facilitates connection and disassembly, avoiding other safety accidents and improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of power distribution maintenance technology, specifically a power distribution maintenance protection device. Background Technology

[0002] Power distribution maintenance refers to the inspection, maintenance, repair, and replacement of equipment and lines in a power distribution system to ensure the safe and reliable operation of the power distribution system, promptly identify and eliminate potential safety hazards in equipment and lines, prevent safety accidents such as electric shock, short circuits, and fires, and protect the safety of maintenance personnel and equipment.

[0003] When carrying out power distribution maintenance, it is usually necessary to use maintenance protection devices to ensure the safety of power distribution maintenance personnel and equipment and to ensure the smooth progress of maintenance work. However, when using protection devices, it is usually necessary to connect a lot of lines to the maintenance equipment, which can easily lead to tangling and messiness between these lines. This not only makes it inconvenient to connect and disconnect, but also easily causes other safety accidents. Therefore, it is necessary to provide a power distribution maintenance protection device. Utility Model Content

[0004] The purpose of this utility model is to provide a power distribution maintenance protection device to solve the problem mentioned in the background art, where the use of the protection device usually requires the connection of many lines with the maintenance equipment, which easily leads to tangling and messiness of these lines, making connection and disassembly inconvenient and prone to other safety accidents. To achieve the above objective, this utility model provides the following technical solution: a power distribution maintenance protection device, including a carrying case body;

[0005] A connecting assembly, comprising a connecting frame, the connecting frame being fixedly connected to one side of the suitcase body, a connecting plate one being fixedly connected to one side of the connecting frame, and a connecting plate two being movably connected to one side of the connecting frame;

[0006] The protection components include a voltage monitoring box, which allows maintenance personnel to monitor the equipment's voltage in real time after connecting the wiring. The voltage monitoring box is fixedly connected inside the carrying case. Inside the carrying case is a fixed current protection box, which contains a current transformer and a short-circuit protection switch. The current transformer monitors current changes in the circuit in real time. When a short-circuit current is detected, the short-circuit protection switch quickly activates, cutting off the circuit to prevent damage to the equipment and personnel. Inside the carrying case is an alarm box, which displays the voltage status on a screen. When the microprocessor detects an abnormal voltage, it triggers a loud buzzer and flashes a corresponding alarm light to alert maintenance personnel.

[0007] Further preferably, the connecting assembly also includes a limiting groove, which is formed on one side of the connecting frame. A limiting block is movably connected to the inner wall of the limiting groove, and a connecting post is movably connected inside the limiting block. A connecting spring is sleeved on the side surface of the connecting post. Under the force of the connecting spring, the second connecting plate and the second cable management groove can move downwards, thereby allowing the first and second cable management grooves to clamp and fix the cable. A lifting block is fixedly connected to the other side of the limiting block. When connecting the cable between the maintenance device and the protection device, the lifting blocks on both sides of the connecting frame can be pulled, thereby causing the limiting block to move... As the connecting plate 2 moves upward, it exerts a squeezing force on the connecting spring. The front of the connecting plate 1 has a cable management groove 1, and the front of the connecting plate 2 has a cable management groove 2. The connecting plate 2 is fixedly connected to one side of the limiting block. A wire hole is provided on one side of the carrying case body. At this point, the wires can be passed through the wire hole one by one in sequence and placed in the cable management groove 1. Then, the lifting blocks on both sides can be released. By installing the connecting components, not only can loosening or tangling of the wires be prevented, but also easy connection and disassembly are facilitated, avoiding other safety accidents and improving the practicality of the device.

[0008] Further preferably, the protection component also includes a wiring hole one, which is opened on one side of the voltage monitoring box; a wiring hole two is opened on one side of the current protection box; a display screen is fixedly connected to the top of the alarm box; an alarm light is fixedly connected to the top of the alarm box; a buzzer is fixedly connected to the top of the alarm box; a voltage sensor is fixedly connected inside the alarm box; a microprocessor is fixedly connected inside the alarm box; a display module is fixedly connected inside the alarm box; and an alarm module is fixedly connected inside the alarm box.

[0009] More preferably, a support frame is fixedly connected to the front of the suitcase body, and a lifting handle is movably connected to one side of the support frame.

[0010] More preferably, a connecting block is fixedly connected to the front of the suitcase body, a slot is provided on the top of the connecting block, and a locking block is fixedly connected to the front of the suitcase body, the locking block being engaged with the inner wall of the slot.

[0011] More preferably, a grounding wire is fixedly connected to one side of the suitcase body, and a ground electrode is fixedly connected to the other end of the grounding wire.

[0012] More preferably, a protective pad is fixedly connected to the inner wall of the suitcase body, and a connecting groove is provided on the front side of the protective pad.

[0013] More preferably, the connecting column is fixedly connected inside the limiting groove, and the lifting block is movably connected to one side of the connecting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, by installing a connecting assembly, when connecting the wiring between the maintenance device and the protection device, the lifting blocks on both sides of the connecting frame can be pulled, causing the limiting block to move the connecting plate two upwards. At the same time, this will exert a squeezing effect on the connecting spring, allowing the wiring to pass through the wire holes one by one in sequence and place these wirings in the cable management groove one. Then, the lifting blocks on both sides can be released. Under the force of the connecting spring, the connecting plate two and the cable management groove two can move downwards, allowing the cable management groove one and the cable management groove two to clamp and fix the wiring. This not only prevents the wiring from becoming loose or tangled, but also facilitates connection and disassembly, avoids other safety accidents, and improves the practicality of the device.

[0016] In this invention, by installing protective components, the internal voltage monitoring box can monitor the voltage of the equipment in real time when maintenance personnel connect the wiring and perform maintenance. Simultaneously, the current protection box, containing a current transformer and a short-circuit protection switch, allows the current transformer to monitor current changes in the circuit in real time. When a short-circuit current is detected, the short-circuit protection switch quickly activates, cutting off the circuit and preventing damage to the equipment and personnel. Furthermore, the display and alarm modules within the alarm box can display the voltage status on the screen. When the microprocessor detects an abnormal voltage, it will trigger a piercing buzzer sound and a corresponding alarm light to flash, thus alerting maintenance personnel and improving the practicality of the device.

At this time, the wiring can be passed through the wire holes 211 one by one in sequence and placed in the cable management groove 209. Then, the lifting blocks 208 on both sides can be released. Under the force of the connecting spring 207, the connecting plate 203 and the cable management groove 210 can move downward, allowing the cable management groove 209 and the cable management groove 210 to clamp and fix the wiring. This allows maintenance personnel to connect the wiring and then inspect the equipment. During maintenance, the internal voltage monitoring box 301 can monitor the voltage of the equipment in real time. At the same time, the current protection box 302, which contains a current transformer and a short-circuit protection switch, monitors the current changes in the circuit in real time.

Meanwhile, the display module 311 and alarm module 312 in the alarm box 303 can display the voltage status on the display screen 306. When the microprocessor 310 determines that the voltage is abnormal, it will cause the buzzer 308 to emit a piercing sound and the corresponding alarm light 307 to flash to alert the maintenance personnel.
