Novel uninterruptible power supply for transformer substation

Abstract

The invention relates to the technical field of power distribution of a power system, in particular to a novel uninterruptible power supply for a transformer substation, which comprises a charging module, a power storage module and an inversion module, and the modules are arranged in control cabinets such as a battery cabinet, a charging cabinet and a power distribution cabinet. Wherein a front door of the battery cabinet is provided with a sliding rail, and a sliding block is arranged on the sliding rail. And the uppermost layer of battery supporting plate of the battery cabinet consists of a longitudinal bracket and a sliding supporting plate. The sliding supporting plate is erected on the two longitudinal supports. A hanging groove is formed in the lower end of the sliding block, and a hanging hook is arranged at the rear end of the sliding supporting plate to form a hoisting platform for hoisting the storage battery. The storage battery bracket has the beneficial effect that the heavy storage battery can be conveniently mounted.

Description

technical field [0001] The invention relates to the technical field of power system power distribution, in particular to a novel uninterruptible power supply for substations. Background technique [0002] In the substation or power distribution station system, in order to ensure the safe operation of the equipment, especially after a temporary power failure or accidental power failure, ensure that the electrical equipment in the substation and power distribution station can operate normally to avoid accidents. , AC and DC systems are configured in the electrical system design of substations and power distribution stations, that is, uninterruptible power supplies are set. The uninterruptible power supply in the current power distribution station and substation is mainly composed of charging cabinets, battery cabinets and power distribution cabinets. The power distribution cabinets are mainly used to realize the distribution of alternating current, alternating current after in...

Problems solved by technology

Using lead-acid batteries has some advantages but is very inconvenient to install

As we all know, the weight of the battery cells used in the power transformation and distribution system is generally heavy, so it is not easy to pick and place, and the battery cabinet is generally equipped with multi-layer brackets. The height of the standard cabinet is 2260mm, so the battery bracket will be in close proximity The position of the meter is set. For the battery bracket at the lower position, although the quality is heavier, it can still be installed. For the battery bracket at the higher position, it is not easy to lift the heavy battery, and generally requires a strong person to complete it.
