Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an automatic braking device. The braking device includes a shell; a trigger mechanism. The trigger mechanism includes a pushing rod that can extend out of the shell, the pushing rod can move back and forth relative to the shell along the axis direction; a monitoring structure is placed inside the shell, it is used to send the monitoring signal; the main control structure, is also placed inside the shell, the main control structure and the monitoring structure and the trigger mechanism connect, for receiving monitoring signals and according to the monitoring signal control the pushing rod in the trigger mechanism to stretch relative to the shell along the axis direction. The aforementioned automatic braking device, the main control structure can control the operating status of the trigger mechanism according to the monitoring signal sent from the monitoring structure, the pushing rod in the trigger mechanism extends and retracts relative to the shell body. In such a way, the automatic braking device realizes fast braking without the direct, manual pressing of the brake button to operate the brake, thus avoiding the inconveniences and economic losses from power disruptions, and effectively assuring the safety of the operator.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an automatic opening device. Background technique [0002] High-voltage switchgear plays the role of on-off, control or protection in power system generation, transmission, distribution, power conversion and consumption, so it is widely used in power systems. If the high-voltage switchgear needs to be opened during use (that is, the circuit breaker is turned from the closed position to the disconnected position), the electric signal is usually used to remotely control the circuit breaker to jump the circuit breaker after the opening coil is charged, or to open the high-voltage switch. Cabinet doors operate directly on the circuit breaker panel. When a fault occurs, if the secondary line is powered off or damaged, the remote operation fails, resulting in the inability to quickly cut off the faulty circuit, which will cause irreparable losses. However, manually opening the cabin...
