Power and energy storage structure of mine anti-explosion frequency control all-in-one machine

Abstract

The invention relates to a power and energy storage structure of a mine anti-explosion frequency control all-in-one machine. The power and energy storage structure of the mine anti-explosion frequency control all-in-one machine comprises a water cooling plate, a water channel is arranged inside the water cooling plate, a copper plate is arranged on the water cooling plate, multiple power devices are arranged on the copper plate, a laminated busbar electrically connected with one power device is arranged on each power device, an insulation support is also arranged on the water cooling plate, the insulation support comprises two support frames which are arranged at the front side and the rear side of the water cooling plate in parallel, multiple separating and fixing plates are arranged in parallel between the two support frames, a plug-in type power capacitor is respectively arranged between every two separating and fixing plates, and the bottom of the plug-in type power capacitor is connected with the power devices. The power and energy storage structure of the mine anti-explosion frequency control all-in-one machine reduces the whole volume of a frequency converter; and plug-in type power capacitors can be directly plugged on a connecting pole and do not need to be connected by cables, so that the whole volume of equipment is reduced; and the plug-in type power capacitor is convenient to dismount, so that dismounting time is saved, working efficiency is improved, a connection inductance is small, no absorption capacitor is required to be arranged on each power device, and mounting error probability is greatly reduced.

Description

technical field [0001] The invention relates to a mine frequency converter, in particular to a power and energy storage structure of a mine explosion-proof frequency conversion speed regulation integrated machine. Background technique [0002] The large-capacity inverters currently used in mines are mainly 1140V flameproof inverters, which need to use 1140V power supply cables for power supply. However, the diameter of 1140V power supply cables is relatively thick, which makes the power supply cost of the inverter higher and occupies underground space. The large space reduces the underground wiring space. Using a 3300V power supply cable to supply power to the frequency converter can solve the above shortcomings, but the 3300V power supply cannot be directly connected, and a frequency converter that matches the 3300V power supply is required, but the 3300V frequency converter is large in size and weight, and still occupies the underground Larger space.
