Description

Flat wall-mounted travelling lamp transformer for metal-nonmetal underground mine

Technical Field

The utility model relates to the technical field of transformers, in particular to a flat wall-mounted travelling lamp transformer for a metal nonmetal underground mine.

Background

The running lamp transformer is a step-down transformer commonly used by mine enterprises, and is mainly used for underground roadway fixed illumination, face-to-face illumination and partial electric tool power supply. In order to ensure the safety of electricity consumption and prevent electric shock accidents, 127V/36V safety voltage is often used for power supply for underground mine illumination and the like. The action of the 'line lamp transformer' is to convert 380V or 220V alternating current into 127V/36V or other safe voltages, and the 'line lamp transformer' at present has single-phase and three-phase and is generally converted into 12V, 24V, 36V, 127V and the like, and is mainly used for occasions with low-voltage power supply, such as local illumination power supply, safe voltage electric tool power supply and the like;

the appearance of a conventional street lamp transformer used in a metal-nonmetal underground mine is of a square structure, the square appearance of the street lamp transformer is unchanged for many years, and the transformer occupies a larger roadway space when installed underground. The prior running lamp transformer is affected by the shape and the installation mode, is generally placed on a roadway bottom plate, is often damaged by collision of trackless equipment, is immersed in water, is corroded by ground moisture and the like, seriously affects the service life of the running lamp transformer, and brings about a plurality of potential safety hazards. The other mounting mode is that the transformer is fixed on the roadway side by the processing bracket, the square appearance of the transformer has larger shape difference with other distribution boxes and the like, so that the standardized construction of mines cannot achieve the unified and coordinated effect, and the standardized management difficulty is increased. The pedestrian and driving safety regulations of the underground roadway have strict requirements on the safety distance between the pedestrian and the two sides of the roadway, the existing roadway transformer occupies limited space of the roadway after being installed, and in order to meet the requirements of the safety distance regulations, the installation position of the roadway transformer needs to be passively selected at a place with relatively wide space of the underground roadway, or the installation position of the roadway transformer needs to be expanded and brushed, so that the installation position of the roadway transformer is not reasonable, or engineering investment is increased by expanding and brushing the roadway. Therefore, we propose a flat wall-mounted travelling lamp transformer for a metal-nonmetal mine underground, which is used for solving the problems.
