Embodiment Construction

[0017] Such as Figure 1 to Figure 3 As shown, a PT-free micro-power intelligent high-voltage switch, which includes an operating mechanism 1, a switch box 2, a phase A vacuum bubble 5, a B phase vacuum bubble 6, a C phase vacuum bubble 7, and a phase A line inlet device 8. Phase B line incoming device 9 , C phase line incoming device 10 , A phase line outgoing device 11 , B phase line outgoing device 12 and C phase line outgoing device 13 . It also includes a power-taking part 3 and a supercapacitor energy storage module 4 with overvoltage protection. A, B, and C three-phase line-entry devices introduce the three-phase high voltage on the power supply side into the switch box, and after passing through the vacuum bubbles of each phase, the power-taking part 3 performs step-down rectification, and then the overvoltage protection The supercapacitor energy storage module 4 is used for energy storage, and the supercapacitor energy storage module and the power-taking part are equ...

Abstract

The invention discloses and provides an intelligent high-voltage switch without a PT (potential transformer). The intelligent high-voltage switch comprises an operating mechanism (1), a switch box body (2), a power taking part (3), an ultracapacitor energy-storage module (4) with over-voltage protection, an A-phase vacuum interrupter (5), a B-phase vacuum interrupter (6), a C-phase vacuum interrupter (7), an A-phase line incoming device (8), a B-phase line incoming device (9), a C-phase line incoming device (10), an A-phase line outgoing device (11), a B-phase line outgoing device (12) and a C-phase line outgoing device (13). According to the invention, the defect that power for the current switch is supplied by the PT is overcome, and as the power supply method that three-phase capacitors are utilized for power taking through voltage reduction, and an ultracapacitor is utilized for energy storage is adopted, a control system taking micro-control as the core is formed by combination with the innovative micro-power consumption design; and the intelligent high-voltage switch has the advantages of miniaturization, energy saving and emission reduction, capability of facilitating environmental protection and the like, can eliminate resonance pollution and PT explosion caused by use of the PT, and can be applied to the field of high-voltage control.

Description

technical field [0001] The invention relates to a PT-free intelligent high-voltage switch. Background technique [0002] At present, with the transformation of the power grid and the construction of a new power grid, there is a market demand for hundreds of thousands of high-voltage switches of 6KV-35KV every year. In recent years, with the large-scale construction of smart grids, these switches have begun to be equipped with various intelligent controllers. The work of the intelligent controller and the opening and closing operations of the switch require power supply. The common power supply is obtained by using PT (potential transformer), that is, the high-voltage line is transformed into the required 220V or 110V voltage as the power supply. [0003] PT is expensive, which affects the process of intelligence; in addition, the main raw materials of PT are silicon steel sheet, copper enameled wire and resin. If all online high-voltage switches in the country are intelli...
