Problems solved by technology

Among them, the neutral line terminal N and the phase line terminal L are arranged on the same side. Therefore, after the current flows through the varistor, it will flow to the opposite side to reach the neutral line terminal N. The distance of current flow is large and will increase. Space occupied by wiring structure

Embodiment Construction

[0053] Combine below Figure 3 to Figure 6 The surge protector of the present invention will be described in detail.

[0054] Figure 5 and Figure 6 The structural schematic diagrams of the surge protector according to the present invention are shown from two opposite sides respectively.

[0055] Such as Figure 5 and Figure 6 As shown, the surge protector according to the present invention includes: piezoresistors 1, 18, gas discharge tube 2, base 3, first terminal 4, second terminal 5 and third terminal 6, rocker arm 8 and trip bar 7. The trip bar 7, the piezoresistor 1 and the gas discharge tube 2 are sequentially arranged above the base 6 from top to bottom. The length direction of the trip lever 7, the piezoresistor 1 and the gas discharge tube 2 are consistent with the length direction of the base, the first terminal 4 and the second terminal 5 are arranged on one side of the base length direction, and the third terminal 6 is arranged on the base the other side ...

Abstract

The invention provides a surge protection device. The width of the surge protection device can be reduced by one half of the width of an existing 1P+N surge protection device. The surge protection device includes a varistor, a gas discharge tube, a base, a first terminal, a second terminal, a third terminal, a rocker arm and a tripping rod; the first terminal is in electric conduction connection with one side of the tripping rod; the other side with the tripping rod is in electric conduction connection with the input side of the varistor; the output side of the varistor is in electric conduction connection with the third terminal; the third terminal is in electric conduction connection with the input side of the gas discharge tube; and the output side of the gas discharge tube is in electric conduction connection with the second terminal. The surge protection device of the invention can have the same performance with the existing 1P+N surge protection device or better performance than that of the existing 1P+N surge protection device, and can maximally withstand 40kA and 8 / 20 s-waveform current.

Description

technical field [0001] The present invention relates to surge protectors, in particular to 1P+N surge protectors. Background technique [0002] The surge protector is usually applied in the circuit and connected in parallel with the load. When a surge occurs in the circuit, it shunts the load and protects the load from being damaged due to the surge in the circuit. [0003] The existing 1P+N surge protector consists of two modules, and each module includes a piezoresistor (MOV) and a gas discharge tube (GDT) respectively. Due to the size limitation of varistors and gas discharge tubes, in the existing products sold by Schneider, this 1P+N surge protector is designed to be 36mm wide, and the module containing the varistor and the module containing the gas discharge tube are respectively 18mm wide. [0004] figure 1 It shows the circuit structure diagram of the existing 1P+N surge protector, which places the neutral line terminal N and the phase line terminal L on one side,...
