Description

Technical Field

[0001] This utility model relates to the field of electrical safety protection, and in particular to electrical safety protection devices. Background Technology

[0002] Electrical safety refers to a series of measures taken to prevent electrical accidents and ensure that personnel and equipment are protected from hazards such as electric shock and electrical fires. Electrical safety protection devices are important equipment to ensure the safe operation of electrical systems. They prevent electrical accidents and protect personnel and equipment from harm through different mechanisms.

[0003] Existing electrical safety protection devices typically protect electrical equipment by automatically cutting off the circuit after a leakage or overload occurs. They cannot provide early warning or circuit cutoff and usually lack insulation protection structures. If electrical equipment is accidentally touched during a leakage or overload, it can easily lead to a safety accident, resulting in insufficient protection.

[0004] Therefore, existing electrical safety protection devices typically only automatically cut off the circuit to protect electrical equipment after a leakage or overload occurs. They cannot provide early warning or circuit cutoff, and usually lack insulation protection structures. If electrical equipment is accidentally touched during a leakage or overload, it can easily lead to a safety accident, resulting in insufficient protection. By installing overload protection components that can detect changes in current, voltage, and temperature inside electrical equipment in real time, early warnings can be provided and the circuit can be automatically cut off before the current, voltage, or temperature reaches the overload limit, resulting in better overload protection. Furthermore, by installing insulation protection components that can provide insulation protection when electrical equipment experiences leakage, leakage can be isolated, preventing leakage safety accidents caused by accidental contact, thus providing better protection and greater safety and reliability. Utility Model Content

[0005] To overcome the problem that existing electrical safety protection devices typically only automatically cut off the circuit to protect electrical equipment after a leakage or overload occurs, they cannot provide early warning or circuit cut-off, and usually do not have insulation protection structures.

Furthermore, by setting an insulation protection component that can provide insulation protection when leakage occurs in electrical equipment, it can play a role in leakage isolation, which can avoid leakage safety accidents caused by accidental contact, providing better protection and greater safety and reliability.

The front end of the insulation protective sleeve is provided with an insulation door for opening and closing. A retaining sleeve for inserting warning reminder paper or card is fixedly installed in the middle of the outer side of the insulation door. The retaining sleeve is transparent.

[0009] Preferably, the inner sides of both the upper and lower ends of the insulating protective sleeve are fixedly connected with five sets of limiting posts evenly distributed, which prevent the upper and lower ends of the electrical equipment body from being touched.

[0010] Preferably, the rear end of the insulating protective sleeve is fixedly equipped with a mounting plate for mounting and fixing the insulating protective sleeve, and the four corners of the surface of the mounting plate are provided with mounting holes for mounting and fixing the mounting plate.

[0011] Preferably, the overload protection component includes a control module, a plug, a temperature sensor, a warning light, a speaker, a first connecting wire, a second connecting wire, and a support plate. The right front end of the control module is fixedly equipped with a plug for electrical connection with the internal components of the electrical equipment body, and the right rear end of the control module is fixedly equipped with a temperature sensor for real-time detection of temperature changes inside the electrical equipment body.

[0012] Preferably, both the plug and the temperature sensor extend through the insulation protection assembly into the interior of the electrical equipment body, and the control module is equipped with a current transformer and a voltage transformer for sensing changes in current and voltage inside the electrical equipment body.

[0013] Preferably, the support plate is fixedly installed on the upper front of the insulation protection component. Speakers for voice warning reminders are evenly distributed and fixedly installed on the upper end of the support plate from left to right. Warning lights for flashing warning reminders are fixedly installed on the upper end of the speakers. The warning lights are electrically connected to the speakers. Adjacent speakers are electrically connected to each other through a first connecting line. The leftmost speaker is electrically connected to the control module through a second connecting line.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-3 This utility model provides an embodiment of an electrical safety protection device, which includes an electrical equipment body 1, an insulation protection component, and an overload protection component. An insulation protection component for insulating the electrical equipment body 1 is sleeved on the outside of the electrical equipment body 1. An overload protection component for preventing overload of internal current or voltage or overheating of the electrical equipment body 1 is fixedly installed on the left end of the insulation protection component.

[0024] Please see Figure 4In this embodiment, the insulation protection assembly includes an insulation protective sleeve 201, a limiting post 202, a connecting post 203, an insulation door 204, a retaining sleeve 205, and a mounting plate 206. Four sets of connecting posts 203 for fixed connection to the electrical equipment body 1 are symmetrically fixedly installed on the inner walls of both the left and right ends of the insulation protective sleeve 201. The connecting posts 203 create a certain gap between the insulation protective sleeve 201 and the electrical equipment body 1 for heat dissipation. An insulation door 204 for opening and closing is provided at the front end of the insulation protective sleeve 201. A card sleeve 205 for inserting warning reminder paper or card is fixedly installed on the outer middle part of 4. The card sleeve 205 is transparent. Five sets of limiting posts 202 are evenly distributed on the inner sides of the upper and lower ends of the insulating protective sleeve 201 and fixedly connected. The limiting posts 202 prevent the upper and lower ends of the electrical equipment body 1 from being touched. A mounting plate 206 for installing and fixing the insulating protective sleeve 201 is fixedly installed at the rear end of the insulating protective sleeve 201. The four corners of the surface of the mounting plate 206 are provided with mounting holes 207 for installing and fixing the mounting plate 206.

[0025] Please see Figure 5 In this embodiment, the overload protection component includes a control module 301, a plug 302, a temperature sensor 303, a warning light 304, a speaker 305, a first connecting wire 306, a second connecting wire 307, and a support plate 308. A plug 302 for electrical connection with internal components of the electrical equipment body 1 is fixedly installed at the front right end of the control module 301. A temperature sensor 303 for real-time detection of internal temperature changes in the electrical equipment body 1 is fixedly installed at the rear right end of the control module 301. Both the plug 302 and the temperature sensor 303 extend through the insulation protection component into the interior of the electrical equipment body 1. The internal part of the device 1 is equipped with a current transformer and a voltage transformer for sensing changes in the current and voltage inside the electrical equipment body 1. The support plate 308 is fixedly installed on the upper front part of the insulation protection component. Speakers 305 for voice warning reminders are evenly distributed and fixedly installed on the upper part of the support plate 308 from left to right. A warning light 304 for flashing warning reminders is fixedly installed on the upper part of the speaker 305. The warning light 304 is electrically connected to the speaker 305. Adjacent speakers 305 are electrically connected to each other through a first connecting line 306. The leftmost speaker 305 is electrically connected to the control module 301 through a second connecting line 307.

[0026] When working, first install and fix the device in the corresponding position. Then, use the mounting plate 206 at the rear end of the insulating protective sleeve 201 to install and fix the device on a suitable wall. Use bolts to pass through the mounting holes 207 and connect to the corresponding wall for fixation. Then, close the insulating door 204 of the insulating protective sleeve 201. After that, insert the relevant warning protective paper or card into the card sleeve 205 to provide safety warning reminders.

[0027] During the operation of the electrical equipment body 1, the overload protection component protects the electrical equipment body 1 from overload. The plug 302, which is electrically connected to the internal structure of the electrical equipment body 1, transmits the current and voltage to the control module 301. The current transformer and voltage transformer inside the control module 301 sense the magnitude of the current and voltage inside the electrical equipment body 1 in real time.

[0028] The temperature sensor 303 senses the temperature changes inside the electrical equipment body 1 in real time.

[0029] When an abnormality is detected in the current, voltage, or temperature inside the electrical equipment body 1, the control module 301 will automatically cut off the circuit and trigger the warning light 304 and the speaker 305 to provide a warning reminder simultaneously.

[0030] When a leakage occurs, the insulation protection component will isolate the leakage current, and even if the outside of the insulation protection component is accidentally touched, no safety accident will occur.

[0031] Through the above steps, by setting up overload protection components that can detect changes in current, voltage, and temperature inside electrical equipment in real time, early warnings can be issued and the circuit can be automatically cut off before the current, voltage, or temperature reaches the overload limit, resulting in better overload protection. Furthermore, by setting up insulation protection components that can provide insulation protection when electrical equipment leaks current, leakage current isolation can be achieved, avoiding leakage current safety accidents caused by accidental contact. This provides better protection and is safer and more reliable. This addresses the problem that existing electrical safety protection devices usually automatically cut off the circuit to protect electrical equipment after leakage current or circuit overload occurs, without providing early warning or circuit cutoff. Moreover, they usually do not have insulation protection structures, making it easy for safety accidents to occur if electrical equipment is accidentally touched during leakage current or overload, resulting in insufficient protection.
