Embodiment approach
[0042] As an embodiment of the present invention, a damping block 29 is provided between the lower end of the slider 28 and the bottom of the inner cavity of the sleeve 25 . Through the setting of the damping block 29, the impact energy of the push plate 35 can be consumed through its own deformation after the movable contact 27 contacts the static contact 26, so as to achieve the purpose of shock absorption and buffering, and avoid the impact of the movable contact due to excessive impact force. 27 Closing failure caused by too large bouncing; at the same time, it also reduces the impact force of the moving contact on the static contact, avoids the coarse deformation of the static contact pier, and further improves the success rate of closing.
[0043] As an embodiment of the present invention, the outer circumference of the first coil 61 and the second coil 62 is provided with a first annular plate 63, and the outer side of the first annular plate 63 is fixedly connected with...

The invention relates to the technical field of power supply and distribution monitoring, in particular to a remote monitoring method for a mine power supply and distribution system. A circuit breakerused in the method comprises a vertically-arranged mounting plate, and a vacuum arc-extinguishing device and an operation maintaining device are sequentially arranged on the front side of the mounting plate from top to bottom; the vacuum arc-extinguishing device comprises an arc-extinguishing chamber, the arc-extinguishing chamber is fixed on a mounting plate through a first fixing frame on the outer side of the arc-extinguishing chamber, a static contact is fixedly arranged on the upper portion of the arc-extinguishing chamber, and the upper end of the static contact is connected with a static conducting rod extending out of the upper end of the arc-extinguishing chamber. The upper part and the lower part of the arc- extinguishing chamber is provided with moving contacts which are rightopposite to the static contact. Through arrangement of an eddy current disc, a first coil and a second coil, rapid separation of the moving contact and the static contact is realized through an electromagnetic repulsion mode, and compared with a spring type separation mode, rapid opening of the circuit breaker is realized so that faults can be rapidly removed, occurrence of safety accidents can beprevented and use requirements of ore circuit power supply and distribution monitoring can be met.
Description
technical field [0001] The invention relates to the technical field of electric power supply and distribution monitoring, in particular to a remote monitoring method for a mine power supply and distribution system. Background technique [0002] In production and life, the power supply and distribution system provides three-phase power supply to various power consumption facilities, and each circuit is controlled through the distribution box. For example, the control of the lighting circuit needs to change according to the season and time, and adjust the lighting time. And turn off the lights when not needed to save energy. The traditional power supply and distribution system has simple equipment and control, low degree of automation, and requires special personnel on duty and patrolling. If a fault occurs, it needs to be searched along the line, which cannot meet the needs of the rapid development of modern society and economy. [0003] The circuit breaker is an indispensab...
