Description

Technical Field

[0001] The utility model belongs to the technical field related to power distribution protection, and specifically relates to a power distribution protection device. Background Art

[0002] Distribution protection is an essential part of the power system. It can cut off the power supply in time when a fault occurs in the power system, protecting equipment and personal safety. The forms of distribution protection mainly include the following: overvoltage protection, grounding protection; undervoltage protection, overcurrent protection and differential protection. Among them, the overvoltage protector is also called the electrical protector, which is mainly used to protect various electrical appliances from being burned by high or low voltage. Existing electrical protectors are usually connected to the power circuit to protect the electrical appliances in the circuit. Electrical protectors are mostly fixed directly with screws, which is not convenient for maintenance, disassembly and replacement. The connection between the electrical protector and the wire is poorly sealed, which has a certain impact on the stability of the line connection.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] like Figures 1 to 3As shown, a power distribution protection device includes a protector body 1 and a fixed mounting plate 7 provided therewith. An upper wiring jack 2 is provided on the top of the protector body 1, and a lower wiring jack 16 is provided on the bottom surface of the protector body 1. An upper wiring fixing hole 3 is provided at a position corresponding to the upper wiring jack 2 on the upper outer side of the protector body 1, and an upper compression screw 4 is installed in the upper wiring fixing hole 3 through a threaded connection. A lower wiring fixing hole 13 is provided at a position corresponding to the lower wiring jack 16 on the lower outer side of the protector body 1, and a lower compression screw 14 is installed in the lower wiring fixing hole 13 through a threaded connection. An external power supply socket 15 is provided on the side of the lower wiring fixing hole 13, a control display panel 8 is provided in the middle position of the outer side of the protector body 1, a mounting slot 6 is provided on the back of the protector body 1, and a snap-fitting platform 18 is provided on the fixed mounting plate 7. The protector body 1 and the fixed mounting plate 7 are fixedly connected by plugging, which is convenient for disassembly, assembly and maintenance of the protector body 1.

[0025] Among them, the upper wiring jack 2 and the lower wiring jack 16 are both equipped with a sealing sleeve 5, which is made of soft rubber material. The side of the sealing sleeve 5 is provided with an opening groove 20. The sealing sleeve 5 can be opened from the opening groove 20 to facilitate installation with the wire.

[0026] A plug-in conical surface 22 is provided at the lower end of the sealing sleeve 5. The diameter of the upper end of the sealing sleeve 5 is larger than the diameter of the upper wiring jack 2. A wire passing hole 21 is provided at the center position of the sealing sleeve 5. The provision of the plug-in conical surface 22 makes it easy to plug the sealing sleeve 5 into the upper wiring jack 2 and the lower wiring jack 16.

[0027] The four corners of the fixed mounting plate 7 are processed with fixed mounting holes 19 , which are countersunk structures. After fixed mounting, the screws are embedded in the panel and will not interfere with the installation of the protector body 1 .

[0028] A snap-fit platform 18 is provided on the outside of the fixed mounting plate 7 , and a slot limiting end platform 17 is provided on the outside of the mounting slot 6 . The installation of the protector body 1 is achieved by arranging the mounting slot 6 and the snap-fit platform 18 .

[0029] A display screen 9 is embedded in the control display panel 8 , an indicator light 12 is provided below the display screen 9 , and a power switch 11 is provided below the indicator light 12 . The indicator light 12 is used to indicate the working status of the protector body 1 .

[0030] A setting button 10 is provided on the side of the power switch 11 . The external power supply socket 15 is a three-phase socket. The setting button 10 can set the protection voltage range of the protector body 1 .

[0031] The working principle of the present utility model is as follows: when the protector body 1 is connected to the circuit, the inlet end of the wire is connected to the upper wiring jack 2, and the outlet end is connected to the lower wiring jack 16. A sealing sleeve 5 is installed in the upper wiring jack 2 and the lower wiring jack 16 to seal and protect the wiring position. By setting the operating voltage in the circuit through the setting button 10 and turning on the power switch 11, the protector body 1 can protect the circuit voltage.

[0032] When the protector body 1 is used as a protection plugboard, the entry end of the wire is connected to the upper wiring jack 2, the plug of the electrical appliance is inserted into the external power supply socket 15, and the working voltage of the electrical appliance is set by the setting button 10. After the setting is successful, the indicator light 12 is on and the display screen 9 will display the current supply voltage value. When the supply voltage is within the preset range, the protector body 1 immediately disconnects the power supply of the electrical appliance, the power indicator light 12 goes out, and the display screen 9 displays the supply voltage value. If the supply voltage returns to the preset range and is stable for 60 seconds, the protector body 1 can turn on the power of the electrical appliance and the power indicator light 12 lights up. Otherwise, the indicator light 12 of the protector body 1 is not on and the power supply of the electrical appliance continues to remain disconnected. If the supply voltage exceeds 380V, the protector body 1 can enter the self-protection state. At this time, the power indicator light 12 goes out and the display screen 9 turns black. Even if the power switch 11 is pressed, the protector body 1 still cannot be turned on. Until the voltage returns to the normal range, the protector body 1 can be manually turned on and continued to be used.

[0033] The novel structure of the present invention is reasonably designed and easy to install and use. A mounting slot 6 is provided on the back of the protector body 1, which is installed in conjunction with a fixed mounting plate 7 and plugged in and fixed for easy disassembly and maintenance. A sealing sleeve 5 is provided at both the upper wiring jack 2 and the lower wiring jack 16 to effectively seal the connection position between the protector body 1 and the wire, providing effective moisture-proof and leakage-proof protection. An external power supply socket 15 is provided at the lower part of the protector body 1, so that the protector body 1 can be connected to the power supply line for use, and can also be used as a plugboard to provide a stable power supply voltage for electrical equipment, thereby having good applicability.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
