Description

Technical Field

[0001] This utility model belongs to the field of electrical grounding resistance technology, specifically relating to a multifunctional real-time electrical grounding resistance detection device. Background Technology

[0002] In modern electrical systems, grounding is a key measure to ensure the safe operation of electrical equipment, the safety of personnel, and the stability of the entire power system. The main purpose of grounding is to provide a safe discharge path for the current when electrical equipment malfunctions, such as insulation damage causing the equipment casing to become live, so that the current can quickly flow into the ground, thereby avoiding electric shock to personnel and damage to equipment. If the grounding is poor, once leakage occurs, operators who come into contact with the equipment casing will suffer electric shock, which may lead to serious injury or death.

[0003] Existing grounding resistance detection devices are difficult to use for real-time grounding resistance detection, requiring operators to perform tests periodically, which greatly increases the workload of staff. In addition, the operation of grounding resistance devices generates a lot of heat, which greatly affects the measurement results. Therefore, a multifunctional electrical grounding resistance real-time detection device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional real-time electrical grounding resistance detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional real-time electrical grounding resistance detection device, comprising a lower housing, an upper housing on top of the lower housing, a detection component inside the lower and upper housings, a temperature sensor and a humidity sensor on the bottom outer side of the lower housing, an alarm device on the top of the lower housing, retaining strips on the bottom sides of the upper housing, a limiting groove on one side of the inner wall of both the lower and upper housings, a motor housing at one end inside the lower housing, a cooling fan at the output end of the motor inside the motor housing, and a connecting box inside the connecting box, wherein a second spring is provided through a groove, a connecting rod is provided at one end of the second spring, a detection plate is provided at one end of the connecting rod, and a guide groove is provided at the bottom of the detection plate.

[0006] In a preferred embodiment, there are two detection plates, each of which is connected to four connecting rods on one side. A grounding electrode is provided between the two detection plates, and the grounding electrode is connected to the detection plate via a wire. The detection plate is connected to an alarm device via a wire.

[0007] In a preferred embodiment, the limiting grooves inside the lower box and the upper box are connected to each other, and the inside of the limiting groove is connected to a wire.

[0008] In a preferred embodiment, ventilation meshes are provided at both ends of the lower box and one end of the upper box, and a ventilation mesh is provided on one side of the cooling fan, with a total of four ventilation meshes.

[0009] In a preferred embodiment, a power supply box is provided at the bottom of the lower housing. The power supply box is connected to the temperature sensor, humidity sensor, alarm device, detection component, and motor inside the motor box via wires.

[0010] In a preferred embodiment, the lower box body has slots on both walls and a fixing groove at one end of each wall. The upper box body has a locking strip at the top of each wall. A first spring is provided at one end of each wall through a groove. A fixing plate is provided at one end of the first spring. A sliding plate is connected to a toggle plate on one side of the fixing plate. The slots and locking strips are X-shaped. The fixing groove is connected to the fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the detection plate in the detection assembly is connected to the connecting box via a second spring and a connecting rod, which allows the detection plate to make better contact with the grounding electrode, ensuring stable and reliable contact. When measuring grounding resistance, stable contact can reduce the influence of contact resistance, thereby improving the accuracy of the measurement. The two detection plates, together with the grounding electrode, are connected by wires to form a measurement circuit, which can accurately measure the grounding resistance value in real time. This allows an alarm device to be activated as soon as the grounding resistance exceeds the safe range, enabling staff to take rapid measures to prevent equipment damage and safety accidents caused by poor grounding.

[0013] This invention utilizes temperature and humidity sensors located on the outer bottom of the lower housing to accurately collect ambient temperature and humidity data in real time. Real-time monitoring of this environmental data provides environmental factor compensation for grounding resistance measurements, further improving the accuracy of the measurement and making the results closer to the true grounding resistance value. A motor inside the motor housing drives a cooling fan, which has a ventilation mesh on one side. Ventilation meshes are also provided at both ends and one end of the lower and upper housings, forming a good ventilation and heat dissipation channel. During prolonged operation, electronic components generate heat. If this heat cannot be dissipated in time, it may lead to performance degradation or even damage. The cooling fan, through forced air convection, rapidly expels heat from the device, lowering the internal temperature and ensuring that all electronic components operate in a suitable temperature environment. This effectively extends the lifespan of the testing device and reduces equipment failures and maintenance costs caused by overheating. Attached Figure Description
