Embodiment

[0011] Embodiment: a computer lightning protection device, comprising an electromagnetic overvoltage relay, the electromagnetic overvoltage relay is provided with four switches: normally open switch K 1 1. Normally open switch K 2 2. Normally closed switch K 3 3. Normally closed switch K 4 4, where the normally closed switch K 3 3 and normally closed switch K 4 4 Connect with the computer 5 through wires to form a power-off circuit, and the normally open switch K 1 1 and normally open switch K 2 2. Connect with the RC absorbing circuit through the wire to form the absorbing circuit. The RC snubber circuit is made of zinc oxide element Z 1 6. Zinc oxide element Z 2 7. Capacitor C 8, resistor R 9, inductance coil L 10, each component is connected in series. The electromagnetic overvoltage relay used is a normally closed switch K when the input voltage does not exceed 220 volts. 3 3 and normally closed switch K 4 4 closed, normally open switch K 1 1 and nor...

Abstract

The invention discloses a computer lighting proofing device, comprising a magnetic overvoltage relay which is provided with four switches: a normal open switch K1, a normal open switch K2, a normal closed switch K3 and a normal closed switch K4; wherein, the normal closed switch K3 and the normal closed switch K4 are connected with the computer by lead wires for forming a power-down circuit; the normal open switch K1 and the normal open switch K2 are connected with an RC absorber circuit by the lead wires for forming an absorber circuit; the RC absorber circuit is composed of a zinc oxide element Z1, a zinc oxide element Z2, a capacitance , a resistance R and an inductance coil which are connected in series. When in use, lightning surge appears, the normal closed switch K3 and the normal closed switch K4 are in an open position, the computer stops working, the normal open switch K1 and the normal open switch K2 are in a close position, the absorber circuit begins to work, thus preventing from producing spark and arc discharge; therefore, the computer is protected; the computer lighting proofing device has the advantages of simple structure, and convenient and flexible usage and the like.

Description

technical field [0001] The invention relates to a computer lightning protection device. Background technique [0002] Computer is popularized at present, but whenever run into thunderstorm weather, most people all can close computer, in case computer is destroyed by the attack of lightning. Although there are lightning protection devices in the prior art, most of them are complex in structure, high in cost, not popular in application, and inconvenient to use. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a computer lightning protection device with simple structure and convenient use. [0004] The present invention is achieved through the following technical solutions: [0005] A lightning protection device for a computer, including an electromagnetic overvoltage relay, on which there are four switches: normally open switch K 1 , normally open switch K 2 , normally closed switch K 3 , norm...
