Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a non-freewheeling switch type lightning protection module, which can solve the problems of traditional lightning protection products such as T1 lightning protection products (10 / 350uS) with limited energy tolerance, slow response time, residual Traditional defects such as high pressure, weak intermittent flow capability, and high cost
At the same time, it effectively solves the disadvantages caused by the traditional T2 large-flow lightning protection products that are accustomed to adopting the pressure-sensitive multi-chip parallel connection to improve the flow capacity. For example, the leakage current of the varistor MOV has the phenomenon of deterioration, tripping, poor tripping, and fire during online operation.

Embodiment 1

[0054] A non-freewheeling switch type lightning protection module, wherein the first dielectric material 11 consists of the following components in parts by weight:

[0055] Component A:

[0056]

[0057] Component B:

[0058]

[0059] The preparation method of the first dielectric material 11 is as follows:

[0060]1) Put the zinc oxide and hydrotalcite powder into the ball mill tank of the planetary ball mill, add deionized water, the weight ratio of deionized water to powder is 1:2, mix and ball mill for 5-7 hours to disperse all the mixed raw materials evenly;

[0061] 2) Add other materials in component A to the slurry obtained in step 1), then add deionized water, the weight ratio of deionized water to slurry is 1.5:1, mix ball mill, ball mill for 12 hours, make all Mix the ingredients until they are evenly dispersed.

[0062] 3) drying the slurry obtained in step 2) to make powder.

[0063] 4) Add all the raw materials of component B, mix and ball mill for 8-...

Embodiment 2

[0081] A non-freewheeling switch type lightning protection module, wherein the first dielectric material 11 consists of the following components in parts by weight:

[0082] Component A:

[0083]

[0084] Component B:

[0085]

[0086] The composition of the second dielectric material 12 is:

Abstract

The invention discloses a no-follow-current switch-type lightning protection module, and the lightning protection module comprises a first support assembly (1), a gas discharge tube (2), a no-follow-current lightning protection assembly (3), and a second support assembly (4). The first support assembly (1), the gas discharge tube (2) and the no-follow-current lightning protection assembly (3) are sequentially connected through connection bolts. The bottom of the no-follow-current lightning protection assembly (3) is connected with the second support assembly (4). The lightning protection module can be suitable for various types of occasions, is simple in structure, is convenient for installation and maintenance, is strong in thunder through-current capability, is low in residual voltage, is low in cost, has no follow current, and is safe and reliable.

Description

technical field [0001] The invention relates to a lightning protection and lightning protection device, in particular to a lightning protection module. Background technique [0002] Lightning is a natural phenomenon in nature. When lightning occurs, super-strong current and voltage will easily cause damage to people's lives and property. Especially with the continuous improvement of people's quality of life, a large number of household appliances have entered the families of ordinary people, which has put forward higher requirements for the current family's electricity consumption environment. [0003] In order to prevent lightning strikes, lightning protection modules are usually installed in the distribution box to form a power supply lightning protection box. The commonly used lightning protection modules currently on the market usually include varistors and discharge tubes. In order to improve its lightning protection effect, the varistor is generally composed of four...
