Problems solved by technology

[0005] 4. The protection of method 3 cannot ensure that the SPD will not catch fire or be struck by multi-pulse overvoltage lightning, and will lead to an increase in cost;
[0006] 5. The protection of method 2 uses a backup protector. When the backup protector is disconnected, the protected object cannot be protected from lightning strikes, and using a backup protector will lead to an increase in residual voltage, which is not conducive to protection

Embodiment Construction

[0044] Such as Figure 1 to Figure 8 As shown, a surge protector MOV chip, the outer side of the MOV chip is insulated and composed of a plurality of unit MOV chips 1 connected in series, electrodes 4 and electrodes 5 are fixed at both ends of the MOV chip and a graphene layer is arranged, and the unit MOV Graphene layers 3 are arranged on both sides of the chip 1;

[0045] The preparation method of surge protector MOV chip comprises the following steps:

[0046] 1.1 First, the ingredients are pressed into a unit MOV chip with a voltage equivalent that can break down but is not enough to burn (it can be square or round) (see figure 1 ), you can also first press the ingredients into a cylinder (or cuboid) and then cut according to a voltage equivalent that the unit MOV chip can break down but is not enough to burn (see figure 1 );

[0047] 1.2 Then in unit MOV chip 1 (see figure 1 ) spray (paint) (print) (cover) (paste) graphene layer 2 on both surfaces (see figure 2 ); ...

Abstract

The invention relates to a surge protection device MOV chip. The outer side of the MOV chip is insulated and is formed by connecting a plurality of unit MOV chips in series. Electrodes are fixed at the two ends of the MOV chip and the MOV chip is provided with graphene layers, and the surfaces of the two sides of each unit MOV chip are provided with the graphene layers. The unit MOV chips of the MOV chip unit can be broken down but is not enough to combust at an equivalent weight. Graphene layers are arranged on the two surfaces of the MOV chip. The whole MOV chip is formed by pressing and sintering a unit MOV chip combination with graphene arranged on the two surfaces, so the whole MOV chip is prevented from being punctured after the unit MOVs are punctured, and the problem that the lightning stroke multi-pulse surge protection device cannot be protected is solved. The problem of fire breakout of the MOV chip is also solved. The surge protection device using the MOV chip does not needto be provided with a backup protection device, so that the product waste is reduced.

Description

technical field [0001] The invention relates to the technical field of surge protector MOV chips, in particular to a surge protector MOV chip and a preparation method thereof. Background technique [0002] 1. The MOV chip of the surge protector is prone to breakdown and fire after being struck by power frequency current or multi-pulse lightning, causing fire hazards. There is a discussion on whether to install surge protectors in the low-voltage electrical appliance committee; [0003] 2. The SC37A surge protector team is discussing using a surge protector backup protection device to protect the surge protector to prevent the surge protector from igniting; [0004] 3. The SC37A surge protector group is discussing intelligent surge protectors to prevent surge protectors from catching fire; [0005] 4. The protection of method 3 cannot ensure that the SPD will not catch fire or be struck by multi-pulse overvoltage lightning, and will lead to an increase in cost; [0006] 5. ...
