Abstract

The invention discloses an adjustable power change switch. The bottom of an operation panel is connected with a terminal; a phase line L1 is electrically connected with a line inlet end L1; a phase line L2 is electrically connected with a line inlet end L2; a phase line L3 is electrically connected with a line inlet end L3; an electric heating pipe DR1 is electrically connected between a line outlet end L1 and the phase line L2; an electric heating pipe DR2 is electrically connected between a line outlet end L2 and the phase line L3; an electric heating pipe DR3 is electrically connected between a line outlet end L3 and the phase line L; and a motor is electrically connected with the phase line L1, the phase line L2 and the phase line L3 through a three-phase line respectively. According to the adjustable power change switch, power conversion of resistive load is achieved; working load and inductance load behind a three-phase switch can also be effectively locked; the adjustable power change switch is safe and reliable; and compared with the traditional alternating-current contact switch, the cost of the switch with the same overload current capacity can be greatly reduced by over 50%.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to an adjustable power conversion switch. Background technique [0002] At present, AC contact switches with single-phase 220V or 380V electromagnetic coils are used. If power conversion is to be realized, three AC contact switches are required for conversion, which greatly increases the cost of switch accessories. To this end, an adjustable power switch is proposed. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable power conversion switch to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an adjustable power conversion switch, including an operation panel, L1 phase line, L2 phase line, L3 phase line, electric heating tube DR1, electric heating tube DR2, electric heating tube DR3 and a motor, The su...
