Abstract

The invention discloses an arc extinguishing power device driving device and an arc extinguishing device, belongs to the field of electricity, and particularly relates to an arc extinguishing power device driving device suitable for being used in an electronic arc extinguishing device and for driving an power device. The to-be-driven power device is parallel to a mechanical switch needing arc extinguishing, the arc extinguishing power device driving device includes a first voltage detection switch, the input end of the first voltage detection switch is connected with the two ends of the power device, the first voltage detection switch is connected in series in a driving circuit of the power device and is conducted when it is detected that a potential difference exists between the two ends of the power device, a driving signal is transmitted to the power device through the first voltage detection switch, the power device is driven to be conducted, and the first voltage detection switch is of a half controlled type switch or a full controlled type, wherein the threshold value of the full controlled type first voltage detection switch is smaller than the on-state voltage of the power device. The arc extinguishing power device driving device has the advantages that a semiconductor device high in voltage resistance is not required, disconnected state of a mechanical switch can be detected in real time, and the driving energy consumption is low.

Description

technical field [0001] The arc extinguishing power device driving device and the arc extinguishing device of the present invention belong to the field of electricity, in particular, an arc extinguishing power device driving device suitable for driving power devices used in electronic arc extinguishing devices of mechanical switches, an arc extinguishing power device driving device for mechanical switches Arc extinguishing device for arc extinguishing. Background technique [0002] At present, in the electronic control system, when mechanical switches such as relays are used to break and control the load, the breaking arc is large, and the electrical life of the mechanical switch is very short. For this reason, electronic arc extinguishing using power devices and mechanical switches in parallel has also appeared. Devices, such as patent number CN01201907.0, named "electronic arc extinguisher"; patent number CN200910306608.6, named "Optocoupler-based hybrid AC contactor passiv...
