Electrostatic equipment, smoke ventilator, and breakdown protection method of electrostatic equipment

Abstract

The invention, which relates to the field of electrical appliances, discloses electrostatic equipment, a smoke ventilator, and a breakdown protection method of electrostatic equipment. The electrostatic equipment comprises an electrostatic module, a detection module and a control module. The electrostatic module includes a functional part (10); the detection module is used for detecting an electric parameter in a circuit (20) of the electrostatic module and sending a signal to the control module; and the control module is used for controlling the circuit (20) to work based on the signal of the detection module. When the working parameter of the functional part (10) in a working state corresponding to the electric parameter reaches a breakdown threshold of the functional part (10), the control module controls the circuit (20) to be disconnected or to reduce the voltage. Therefore, breakdown occurrence can be monitored effectively by the electric parameter detected by the detection module and corresponding measures are taken for the circuit by the control module to realize restoration of a non-breakdown state, so that continuous occurrence of breakdown as well as damages caused by the breakdown can be avoided.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an electrostatic device, a range hood and a breakdown protection method for the electrostatic device. Background technique [0002] In the use of electrostatic devices (used for discharge or for generating electrostatic fields, etc.), the use environment may cause breakdown, resulting in damage to electrical components (such as electrode plates). Especially for range hoods that use electrostatic adsorption for degreasing, because the electrostatic devices used for them are exposed to the harsh environment of oil fumes, the environment in which they are used changes drastically, and they are more likely to break down and generate arcs, which will cause personal injuries or cause fire. [0003] Therefore, existing electrostatic devices lack effective breakdown protection measures. Contents of the invention [0004] The purpose of the present invention is to overcome the bre...
