Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically to an electrical safety early warning device for power generation areas. Background Technology

[0002] Electrical safety early warning equipment in power generation areas mainly includes the following categories:

[0003] Current monitoring device: used to monitor the current in the circuit in real time; when the current exceeds the set threshold, it will issue a warning signal to indicate that there may be faults such as overload or short circuit; for example, a residual current device (RCD) can detect abnormal residual current in the circuit and quickly cut off the circuit when the residual current reaches a certain value to prevent electric shock and electrical fire accidents.

[0004] Voltage monitoring device: It can monitor the fluctuation of the power grid voltage in real time; when the voltage is over-voltage, under-voltage, or the voltage fluctuation exceeds the normal range, it will issue an early warning in time.

[0005] Temperature monitoring equipment: Electrical equipment in the power generation area generates heat during operation. Excessive temperature may damage the equipment or even cause a fire.

[0006] Insulation monitoring device: used to monitor the insulation performance of electrical equipment; by detecting parameters such as insulation resistance and dielectric loss, it determines whether the insulation of the equipment is good;

[0007] Taking the residual current device (RCD) in a current monitoring device as an example, its electrical safety early warning principle is as follows: Under normal conditions, the current flowing to the load through the live wire is equal to the current returning through the neutral wire; when an electrical fault occurs, such as leakage in a live conductor, the current returning to the neutral wire will decrease, generating a residual current; the zero-sequence current transformer in the device will sense and detect this unbalanced current. Its main phase wire is connected to the input terminal of the primary winding, and the neutral wire is connected to the input terminal of the secondary winding, with the induction coil wound between the two; under fault-free conditions, the instantaneous current vector sum on the current transformer detection winding is almost zero; however, when leakage occurs or a person comes into contact with a live conductor, some current flows out from the live line, causing an imbalance in the sensing current transformer, which in turn generates an equivalent current in the induction coil; the current signal generated by the induction coil is transmitted to the relevant processing circuit; this electrical... The circuit compares the detected residual current value with a preset reference value. Typically, in Australia and some European and Asian countries, the residual current trip value is set to 0.030 amps. When the residual current reaches or exceeds this set value, subsequent actions are triggered. Once the residual current exceeds the threshold, the permanent magnet relay in the device will trip. In the static state, the relay armature is tightly attracted by the magnet, keeping the power supply line and neutral wire of the external mechanism open, and the load operates normally. When residual current leakage is detected, the current from the induction coil causes the PMR coil to induce a repulsive magnetic field, weakening the permanent magnet attraction. The spring force pulls open the relay armature, and the external mechanical contacts or integrated switch contacts quickly disconnect, cutting off the power supply line of the circuit, realizing electrical safety early warning and protection, preventing dangerous situations such as electric shock and electrical fire, and achieving the purpose of electrical early warning.

[0008] When the aforementioned residual current operated protective device is in actual operation, in public or densely populated places, as well as in industrial / construction site scenarios, the device may be hit by tools or building materials (such as steel pipes and steel bars), causing the casing to crack or the internal components to loosen, threatening electrical safety.

[0027] Please see Figure 1-6 This utility model provides an electrical safety early warning device for power generation areas, including a residual current device 1. The outer side of the residual current device 1 is covered with a protective armor 3. Both sides of the surface of the residual current device 1 are equipped with docking components 2. The residual current device 1 is connected to the protective armor 3 through the docking components 2 on both sides. The top of the protective armor 3 is provided with a top protective net 31. A side protective net A32 is installed on one side of the top protective net 31, and a side protective net B33 is installed on the other side of the top protective net 31.

[0028] Working Principle: In actual use, the protective armor 3 is first fixedly placed on the outside of the residual current operated device 1. The specific installation method is as follows: Hold the protective armor 3 in your hand. The mounting platforms 22 on both sides of the bottom of the protective armor 3 are inserted into the guide rails 23. At this time, an end seat 25 is fixedly installed on one side of the guide rail 23. The end seat 25 has through holes 24 inside, and the fixing bolts pass through the through holes 24 and are screwed into the screw holes 26. The protective armor 3 is installed on the residual current operated device 1 through the guide seat 21 and the guide rail 23. This allows for quick positioning and installation of the protective armor 3 on the outside of the residual current operated device 1. The cooperation between the guide seat 21 and the guide rail 23 ensures that the protective armor 3 is accurately installed on the outside of the residual current operated device 1, avoiding installation position deviations and ensuring the protective armor... The protective armor effectively protects the equipment from external factors; rapid positioning and installation saves installation time and labor costs; installers do not need to spend a lot of time aligning and adjusting, improving work efficiency, especially when batch installation or emergency situations require rapid installation of the protective armor, this method has obvious advantages; the connection between the guide seat 21 and the guide rail 23 usually provides a relatively stable connection, making the protective armor and the residual current device 1 tightly connected, not easy to fall off due to external impact or vibration, ensuring that the protective armor always stays in the correct position during equipment operation and plays a reliable protective role; not only is it easy to install, but when it is necessary to inspect, maintain or replace the protective armor of the residual current device 1, the protective armor can also be easily removed without damaging the equipment itself, and the disassembly process is also quick, which helps to improve the maintenance efficiency of the equipment;

[0029] The residual current operated device 1 is encased in a protective armor 3. The protective armor 3 is equipped with a top protective mesh 31, side protective meshes A32 and B33, and a front protective mesh 34, covering the sides, front, and top of the residual current operated device 1 respectively. This provides multi-faceted protection for the residual current operated device 1, offering comprehensive buffering and protection against accidental impacts or compression, reducing the risk of equipment damage, and ensuring its normal operation in various complex working environments. The mesh structure design provides protection without obstructing the normal heat dissipation of the residual current operated device 1. The presence of the top protective mesh 31 and the side protective meshes A32 and B33 increases airflow channels, facilitating the removal of hot air from the top. The exhaust is directed to the side, allowing cool air to enter from the side, creating good convection, improving heat dissipation efficiency, and preventing equipment performance degradation or malfunction due to overheating. The top protective net 31, side protective nets A32, side protective nets B33, and front protective net 34 adopt a hollow design, which does not affect the observation of the residual current operated device 1. Staff can easily view the equipment's operating status indicator lights, display screens, etc. through the protective nets to understand the equipment's working status in a timely manner without disassembling the protective armor, thus improving the efficiency of daily inspections. The protective armor is preferably made of plastic insulating material, which has a certain degree of hardness while being non-conductive, wrapping the live parts of the residual current operated device 1 inside, reducing the possibility of personnel accidentally contacting live parts, lowering the probability of electric shock accidents, and protecting the safety of on-site personnel.

[0030] The specific methods by which residual current operated protective devices provide safety warnings for electrical equipment in power generation areas have been fully disclosed in the background art and are not essential technical features to be protected in this application, so they will not be described again here.
