Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 The energy storage unit that provides short-term high-power supply to the servo motor is shown, including: rectification and boosting device, DC-DC conversion module, output rectification and filtering module, energy storage control and its auxiliary power supply, large-capacity energy storage (large-capacity Capacitor module, medium-capacity capacitor module connected in parallel), safety discharge control device and energy consumption device, etc.;

[0031]1) Rectifying and boosting device: one end is connected to the input of a single-phase low-power power supply (AC or DC, not more than 6KW), which is used to convert the AC power into DC, and perform inverter and re-boost;

[0032] 2) DC-DC conversion module: quickly realize the control of the input voltage;

[0033] 3) Output rectification and filtering module: r...

Abstract

The invention discloses an energy storage unit for supplying short-time high-power supply and a method. The input of a single-phase low-power power supply (alternating current or direct current, not greater than 6KW) passes through a rectifying and voltage-boosting apparatus, a DC-DC conversion module and an output rectifying and filtering module to transmit electric charges to a high-capacity energy storage which consists of multiple high-capacity capacitor modules and a medium-capacity capacitor module; and the process is completed within a few hundred seconds. After the high-capacity energy storage completes energy storage, single-phase short-time high-power output can be provided for the outside, so that the power supply requirement of a motor direct drive type operating mechanism can be satisfied; the energy storage unit has the advantages of modular structure, high energy storage density, high energy storage speed, diversified working patterns, safety and reliability in use, light weight, convenience in energy storage expansion and the like; the problem of dependence of short-time operation of high-capacity equipment on the conventional high-capacity power supply can be solved; and in addition, long-distance and large-section conductor power transmission can be avoided, the cost is lowered, and the adaptivity and mobility of the short-time high-power equipment are improved.

Description

technical field [0001] The invention relates to the technical field of power supply for a servo motor driver of a high-voltage switch, in particular to an energy storage unit and a method for providing short-term high-power supply. Background technique [0002] At present, with the development of intelligent technology, domestic and foreign enterprises have carried out a lot of intelligent technology research on high-voltage switch products, and more and more new components and new technologies are applied to high-voltage switches, especially various sensors and communication technologies. The application of the high-voltage switch reduces the volume of the high-voltage switch product and obtains the data of the high-voltage switch under various working conditions. However, the core equipment for driving the high-voltage switch action—the spring operating mechanism (especially for circuit breaker products of 126KV and above), still uses the traditional mechanical transmissio...
