Embodiment Construction

[0021] Such as Figure 3-5 As shown, the present invention includes at least one discharge module and a performance indicating circuit connected between two lines of the power supply phase line, neutral line and ground line respectively, such as Figure 5 The discharge module shown is composed of a main discharge circuit and a start-up circuit connected in parallel, where the main discharge circuit is composed of a piezoresistor VR 2 and gas discharge tube G 1 Composed in series, the start-up circuit consists of a piezoresistor VR 1 composition. In order to effectively reduce the gas discharge tube G under the normal power supply of 220V 1 The partial pressure across the gas discharge tube is guaranteed to reduce G 1 In the case of a certain starting voltage, the gas discharge tube G will not be damaged due to fluctuations in 220V 1 ,Such as Image 6 As shown, the gas discharge tube G of the above-mentioned main discharge circuit in this embodiment 1 There is a resistor...

Abstract

The lightning arrester for power source is composed of at least more than one discharging modules and performance figure circuits that are connects to two lines among phase line, zero line or ground line. The discharging module consists of main discharging circuit and starting circuit connected in parallel. The main discharging circuit includes voltage dependent resistor VR2 and gas discharge tube in serial. The starting circuit includes voltage dependent resistor VR1. The invented device solves the issue of high residual pressure before starting the gas discharge tube completely by using the structure of combining the main discharging circuit and the gas discharge tube. After the gas discharge tube starts, then the main discharging circuit does main discharging task. Morecover the element with lower starting voltage can be selected for the gas discharge tube and the voltage dependent resistor, so as to realize lower residual pressure, higher starting voltage and higher response speed.

Description

technical field [0001] The invention relates to a power surge protector, in particular to a discharge module for a power surge protector. Background technique [0002] The power surge protector (also known as lightning arrester or surge protector, referred to as SPD) is composed of several discharge modules. Therefore, the performance of the power surge protector basically depends on the performance of the discharge module. [0003] At present, the discharge module of each power surge protector mainly adopts such as figure 1 A single zinc oxide varistor (MOV) is shown, and there are also a few such as figure 2 The combination of MOV and gas discharge tube (GDT) is shown, among which MOV mostly adopts Siemens SIOV-B32 series products or SIOV-B40 series products. GDT has WP products, Siemens products, etc. Its basic working principle is: [0004] exist figure 1 , when the voltage U between points A and B AB Varistor voltage U above MOV 1V When the varistor VR 1 conduc...
