Embodiment Construction

[0008] In Figure 1 and Figure 2, discharger (1, 2), screws (3, 4), ground wire (5), ground screw (6), output terminal (7), input terminal (8), knife Switch fulcrum (9), knife switch (10), base plate (11), fuse (12), pit (13), knife cover box nail (14), fixed base plate mounting nail (15).

[0009] The main principle of the present invention is: when lightning enters the house along the wire, the lightning is directly introduced into the ground through the sharp gap discharge of the knife switch discharger, which protects the safety of electrical equipment and humans and animals.

[0010] In Fig. 1 and Fig. 2, on the basis of the existing knife switch, there is a transverse pit 13 on the lower end plate surface of the bottom plate 11, which is used to install the lightning protection device. The lightning protection device has two oppositely installed dischargers 1 and 2 The output power terminal 7 is connected with discharger 1, and the ground is also connected with discharger...

Abstract

The invention discloses a lightning switch wherein, the lower end of a bedplate is provided with a transverse pit for mounting a lightning arrester which is composed of two discharge devices arranged correspondingly; the output power-line terminals are connected with one discharge device, and the earth wire is connected with the other discharge device; usually the two discharge devices have space in between and do not contact each other; however, when lightnings appear, the discharge devices in the pit are respectively connected with output terminal of each phrase and with the earth wire. The earth wire is fixed on the underside of a panel. The invention is simper in structure, good in lightning protective performance, low in cost, convenient to assemble and maintain and worthy of promotion.

Description

technical field [0001] The present invention relates to a knife switch, and more specifically, relates to a knife switch for lightning protection. technical background [0002] At present, in many places, TV sets, motors, and electrical equipment are often burned by lightning, causing fires, and even killing and injuring people. If a lightning rod is installed separately, its cost is high again. Contents of the invention [0003] In order to overcome the above-mentioned existing technical problems, the present invention provides a knife switch with a lightning protection device with a simple design and installation structure based on the existing knife switch. [0004] The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: on the basis of the existing knife switch, there is a transverse groove on the lower end plate surface of the bottom plate for installing the lightning protection device. The electric appliance is comp...
