Servo electric propulsion device for low voltage feed switch breaker

Abstract

The invention provides a servo electric propulsion device for a low voltage feed switch breaker. The device comprises a propulsion machine, wherein the propulsion machine comprises a bottom board, the bottom board is perpendicularly provided with a static supporting board, the static supporting board is provided with a static contact of a plug connector, two sides of the bottom board are symmetrically provided with bearing blocks, two ends of the bearing blocks are provided with bearing wheels, a sliding board is arranged between the bearing wheels, one end of the sliding board is provided with a moving supporting board, a motor and the propulsion device, the moving supporting board is provided with a moving contact of the plug connector, the propulsion device is attached to the supporting board and is arranged on the sliding board, and a bearing board is arranged on the bearing blocks. The device is advantaged in that load power of the servo motor can be reduced, reliable isolation between the breaker and three-phase power source input can be realized, reliable power off can be realized, and a safety coefficient of a coal mine feed switch is greatly improved.

Description

Technical field [0001] The invention relates to the field of mining equipment, in particular to improvements in mine low-voltage feeder switch circuit breakers and auxiliary control equipment, and in particular to a low-voltage feeder switch circuit breaker servo electric propulsion device. Background technique [0002] With the development of my country’s economy, mine lighting is particularly important. At present, most of the circuit breakers used in the low-voltage feeder switch are directly fixed. The input and output of the circuit breaker are all cable connections. When the feeder switch is opened, Isolation of input and output only relies on vacuum tubes for isolation. A few feeder switch circuit breakers are isolated from the input and output parts, but most of them use manual propulsion. When the circuit breaker is off for maintenance, it needs to be pulled out and pushed manually. [0003] Therefore, a low-voltage feed switch circuit breaker servo electric propulsion devi...

[0002] With the development of my country's economy, mine lighting is particularly important. At present, most of the circuit breakers used in low-voltage feed switches are directly fixed. The input and output of circuit breakers are connected by cables. When the feed switch is opened, The isolation of input and output only depends on the isolation of vacuum tubes. There are a few feeder switch circuit breakers that are isolated from the input and output parts, but most of them are manually pushed. When the circuit breaker is powered off for maintenance, it needs to be pulled out and pushed manually.
