Abstract

The invention discloses a three-pole discharge body and a discharge trigger circuit. The discharge trigger circuit includes a three-pole discharge structure and a gap body, and the three-pole structure includes a positive electrode L, a negative electrode N / PE and a trigger electrode C, and discharge positions are located between the positive electrode L and the negative electrode N / PE, and the periphery of the positive electrode L and the negative electrode N / PE is located with a stainless steel sleeve A and a stainless steel sleeve B in turn. The stainless steel sleeve A and the stainless steel sleeve B uss cone double threaded. The trigger electrode C with the stainless steel sleeve A and the stainless steel sleeve B together constitute a trigger electrode. The distance between the positive electrode L and the negative electrode N / PE is 6mm. The three-pole discharege gap body and the discharge trigger circuit each has an electrode at both ends of the body in the gap, in the event of over-voltage surge when the instantaneous conduction occurs between the two electrodes through one of the grounded discharge electrode of the surge energy, so as to achieve the purpose of protection, while the third electrode accelerates the body gap discharge.

Description

technical field [0001] The invention relates to a three-pole discharge gap body and a discharge trigger circuit thereof. Background technique [0002] There are three types of gap body discharge: air gap body, graphite gap body, and multilayer discharge tube gap body. When the gap body is applied to the protection of L-N / PE, the discharge maintenance voltage of the L electrode and the N / PE electrode is only tens of volts, and when the power frequency crosses zero, the internal discharge cannot be effectively cut off, so the gap body type surge protector must solve the gap For the arc extinguishing problem of the main body, the current products use the physical arc extinguishing angle to extinguish the arc, and some use the increase in the number of gaps in the main body layer to increase the discharge maintenance voltage for arc extinguishing. The surge protector with arc extinguishing angle depends on the internal air flow, although it can extinguish the arc most of the ti...
