Abstract

The invention is applicable to the technical field of surge protectors, and provides a high-voltage lightning-proof surge suppression circuit, a device and a power adapter, comprising a varistor, a discharge tube, a high-voltage capacitor, an inductance and a resistor. One end of the varistor is connected with a fire wire or a neutral wire, and the other end is grounded through the discharge tube.The high-voltage capacitor is connected in parallel at both ends of the varistor, and the inductance and the resistor are connected in series in parallel at both ends of the discharge tube. The invention can be used under the condition of withstanding voltage requirement of 1500VAC, and can discharge discharge surge current when surge peak voltage is 1600V, and residual voltage is lower than 1.3KV; It can also be used under the condition of withstand voltage requirement of 3000VAC, and discharge surge current can be discharged when surge peak voltage is 3600V, and residual voltage is lower than 3KV. It can also be used under the condition of withstand voltage requirement of 3000VAC. Under the condition of withstand voltage requirement of 1500VAC or 3000VAC, the current is lower than 5mAand no flashover occurs; And meets the basic insulation requirements, and the equivalent resistance is greater than 10M ohm under the condition of 500VAC.

Description

technical field [0001] The invention belongs to the technical field of surge protectors, in particular to a high-voltage-resistant lightning protection and surge suppression circuit, device and power adapter. Background technique [0002] Causes of surges (transient pulses) usually include lightning, poor grounding, inductive load switching, mains troubleshooting, and electrostatic discharge (ESD), which can result in data loss (or damage) or even equipment damage, among which Lightning surges are the most damaging. [0003] The existing lightning protection method usually uses a high-voltage ceramic gas discharge tube in the power adapter of the electrical equipment. For example, under the condition that the withstand voltage is required to be 1500VAC, a ceramic gas discharge tube with a DC breakdown voltage of 2500V or more is used. The voltage is 3000V. For surges with a voltage of 2121V to 3000V, the discharge tube does not operate and cannot play a role in lightning pr...
