Abstract

The invention discloses a power grid intelligent voltage regulator on-load tap machinery switch comprising a housing in a rectangle structure; a support plate is arranged on the bottom outside the housing; a wire port is arranged above the support plate of the housing; a core 1 and a core 2 are fixed in the housing via insulation supports, and respectively in an oval structure; a first level coil,a second level coil, a third level coil and a fourth level coil are arranged from left to right in sequence outside the side wall of the core1 and core 2; three light rods are arranged in middle of the core 1 and the core 2; the power grid intelligent voltage regulator on-load tap machinery switch employs an electromagnet as the power input, uses weak current for heavy current control, and the housing is filled with an inert gas, thus preventing arcing when contacts open and close, and preventing equipment fire ignition.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an on-load tap mechanical switch for a grid intelligent voltage regulator. Background technique [0002] The grid intelligent voltage regulating device (referred to as voltage regulator) is used in the power grid transmission line to perform automatic contact conversion without interrupting the load current, changing the number of turns of the transformer, thereby adjusting the output voltage of the transformer to make it Meet the voltage regulation standard. However, due to the use of the motor as the power input, the existing equipment will cause poor contact due to mechanical wear for a long time, and easily cause dangers such as fire. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an on-load tap mechanical switch for a power grid intelligent voltage regulator, which...
