Abstract
The utility model discloses a kind of power lightning protection socket, including live wire, zero line and ground wire, it is respectively equipped with inductance coil on live wire and zero line, described live wire is provided with hot electric fuse, being provided with the first varistor and the second varistor between live wire and zero line, connect respectively between described live wire and ground wire, zero line and ground wire the 3rd varistor, the 4th varistor, at one Indication of Losing Efficacy lamp of common series connection after the three, the 4th varistor parallel connections.This power lightning protection socket is simple, safe and reliable, and discharge current is big, and response time is fast, and lightning protection effect is good.
Description
Technical field
This utility model relates to a kind of socket, more particularly to a kind of power lightning protection socket.
Background technology
Now with developing rapidly of science and technology, the electric equipment that people use also gets more and more, and the inside of electric equipment
Structure is more and more accurate, sensitive, but due to the existence in this strong external interference source of thunder and lightning, electric equipment often because
It is struck by lightning and is subject to the biggest destruction.For avoiding socket to be struck by lightning, people have invented the Thunder preventing socket with lightning protection effect, but at present
Thunder preventing socket structure more complicated and lightning protection effect is poor, the most circuit is not carried out safe handling, the most corresponding prompting sets
Standby.
Utility model content
In order to solve above-mentioned technical deficiency, this utility model provides a kind of power lightning protection socket.
This utility model be the technical scheme is that a kind of power lightning protection socket, including live wire, zero line, ground wire, hot melt
Disconnected device, inductance coil, varistor and Indication of Losing Efficacy lamp, described live wire and zero line are respectively equipped with the first inductance coil, second
Inductance coil, described live wire is provided with thermal cut-off, is provided with the first varistor and the second pressure-sensitive electricity between live wire and zero line
Resistance, each series connection the 3rd varistor, the 4th varistor between described live wire and ground wire, zero line and ground wire, the three, the 4th is pressure-sensitive
After resistor coupled in parallel the most jointly series connection one Indication of Losing Efficacy lamp.
Preferably, during described Indication of Losing Efficacy lamp bright (HONGGUANG), represent that its lightning protection component lost efficacy, otherwise, it means that lightning protection
Assembly is normal, and Indication of Losing Efficacy lamp sends thunderbolt when being struck by lightning and reminds.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of this utility model power lightning protection socket lightning protection part
In figure: FU, hot electric fuse, L1, the first inductance coil, L2 the second inductance coil,
R, Indication of Losing Efficacy lamp, MOV1, the first varistor, MOV2 the second varistor, MOV3, the 3rd varistor,
MOV4, the 4th varistor, L, live wire, N, zero line, PE, ground wire.
Detailed description of the invention
In order to be able to be more clearly understood that the technical solution of the utility model, further to this utility model below in conjunction with the accompanying drawings
Explanation.
Fig. 1 is the circuit diagram of power lightning protection socket lightning protection part, including live wire L, zero line N, ground wire PE, thermal fuse F U,
Inductance coil, varistor MOV and Indication of Losing Efficacy lamp R, described live wire L and zero line N is respectively equipped with the first inductance coil L1,
Second inductance coil L2, described live wire L are provided with hot electric fuse FU, are provided with the first varistor between live wire L and zero line N
MOV1 and the second varistor MOV2, each series connection the 3rd varistor between described live wire L and ground wire PE, zero line N and ground wire PE
MOV3, the 4th varistor MOV4, connect after the three, the 4th varistor parallel connections an Indication of Losing Efficacy lamp R the most jointly.Described mistake
During effect display lamp R bright (HONGGUANG), representing that its lightning protection component lost efficacy, otherwise, it means that lightning protection component is normal, Indication of Losing Efficacy lamp exists
Thunderbolt can be sent when being struck by lightning remind.
When thunderstorm weather supply socket is struck by lightning when, can produce overvoltage and overcurrent, wherein varistor is
Big feature is that the electric current flowing through it is minimum, is equivalent to one and shuts when being added in the voltage above it and being less than its threshold value " UN "
Valve, when voltage is more than UN, its resistance diminishes, the electric current thus making to flow through it increase sharply and to other circuit
Impact change is little thus reduces the overvoltage impact on follow-up sensitive circuit.Utilize this function, can be with warp in suppression circuit
The abnormal overvoltage often occurred, protects the circuit from the infringement of overvoltage；Thermal cut-off can effectively prevent the danger of overcurrent
Evil, can make circuit generation open circuit when electric current is excessive when, it is to avoid dangerous；Inductance coil can effectively filter out when thunderbolt
The interference of high-frequency current signal.
This utility model power lightning protection socket is simple, safe and reliable, and discharge current is big, and response time is fast, and lightning protection is imitated
The best, it is provided with Indication of Losing Efficacy lamp, it is possible to display module degradation failure.
Principle of the present utility model is simply described, without departing from this utility model described in above-described embodiment and description
On the premise of spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within requirement and protect
In the range of this utility model protected.This utility model claims scope and is defined by appending claims and equivalent thereof.
Claims (2)
1. a power lightning protection socket, it is characterised in that: include live wire, zero line, ground wire, thermal cut-off, inductance coil, pressure-sensitive electricity
