A Coal Mine Underground Intelligent Power Center

Abstract

The invention belongs to the high and low-voltage switch box technical field and relates to a coal mine underground intelligent power center. A first opening is formed at one side surface of the high-voltage cavity of a combination switch box; a high-voltage output end and a low-voltage input end are arranged in the first opening; a second opening is formed in a dry-type transformer; a high-voltage lead and a low-voltage lead are arranged in the second opening; the first opening is connected with the second opening through a flange interface; the top surface of the high-voltage cavity is provided with two high-voltage input cable connectors in parallel; the high-voltage output end is connected with the high-voltage lead; the low-voltage lead is connected with a low-voltage output end; a control unit is arranged in the combination switch box; a high-voltage input line and a low-voltage output line are both connected with the control unit; an upper open groove and a lower open groove are formed in the rear side plate of a low-voltage cavity; and the outer walls of the upper open groove and the lower open groove are connected with a radiator. The coal mine underground intelligent power center can satisfy power supply demands and provide a protection function. A spaced occupied by the coal mine underground intelligent power center can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of high and low voltage switch boxes, in particular to an intelligent power center under a coal mine. Background technique [0002] With the development of society, coal mine technology is becoming more and more developed, and it has been realized to control the equipment through the controller in the mine; but in the existing technology, the power center generally adopts a high-voltage protection device-dry-type transformer-low-voltage combination switch combination In this way, the high-voltage protector and the low-voltage combined switch are arranged on both sides of the dry-type transformer. The length of the power center of this structure is too large, and the low-voltage side switch only has a power frequency circuit. Protector and belt machine protection device equipment, resulting in large equipment footprint, complex equipment installation and arrangement, and the control between equipment is integ...

[0002] With the development of society, coal mine technology is becoming more and more developed, and it has been realized to control the equipment through the controller in the mine; but in the existing technology, the power center generally adopts a high-voltage protection device-dry-type transformer-low-voltage combination switch combination In this way, the high-voltage protector and the low-voltage combined switch are arranged on both sides of the dry-type transformer. The length of the power center of this structure is too large, and the low-voltage side switch only has a power frequency circuit. Protector and belt machine protection device equipment, resulting in large equipment footprint, complex equipment installation and arrangement, and the control between equipment is integrated, the information is independent, the control is scattered and complicated, and there are high requirements for equipment operators. View When the device is in status, it is necessary to observe the display screen information of each device separately. Data upload and remote control also require different settings for different devices and independent communication control lines. Not only is the operation cumbersome, but the system stability is low; Scattered, and the cable arrangement is particularly complicated and chaotic, which brings certain difficulties to equipment repair and maintenance
