Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Intelligent monitoring device embodiment:

[0038] Such as figure 1 Shown is a schematic diagram of the high-voltage switchgear and its mechanical characteristic monitoring device of the present invention, and the monitoring device includes a central processing unit, a data transmission module and a dormancy wake-up trigger circuit module.

[0039]The central processing unit is a long-sleep module, which is always in a dormant state when there is no action information of the high-voltage switch. Once the action travel information of the high-voltage switch is detected, it will be triggered to wake up. The central processing unit is provided with a signal input terminal for receiving digital detection signals of the stroke sensor, small current sensor and high-voltage switch position auxiliary switch installed in the high-voltage circuit breaker operating mechanism b...

Abstract

The invention relates to high voltage switchgear and a machinery characteristic monitoring device thereof; the machinery characteristic monitoring device comprises a central processor, a data transmission module and a sleep wake up trigger circuit module; the central processor refers to a long sleep module, and is provided with a signal input end used for receiving digital quantity detection signals of a stroke sensor, an undercurrent sensor and a high voltage switch position auxiliary switch arranged in the high voltage breaker operating mechanism box; the sleep wake up trigger circuit module is provided with a port used for receiving a detection signal of the stroke sensor, and the output end is connected with a wake up trigger end of the central processor, so the central processor can be awakened when the stroke sensor detects high voltage switch stroke information, thus solving the problems that an existing high voltage switch machinery characteristic monitoring system is complex in structure, large in energy consumption, and low in data transmission reliability.

Description

technical field [0001] The invention relates to a high-voltage switchgear and a mechanical characteristic monitoring device thereof, which are mainly used for monitoring mechanical characteristic data and fault analysis during the operation of the high-voltage switchgear. Background technique [0002] At present, the condition-based maintenance of power equipment is being vigorously promoted in China. High-voltage switchgear is an important component of the power system, and its equipment reliability has a crucial impact on the reliability of the power system operation. The mechanical state of high-voltage switchgear can directly reflect the overall condition of the control circuit, operating mechanism and transmission system. [0003] The existing high-voltage switch mechanical characteristic monitoring system has a complex structure. Each circuit breaker needs to be equipped with a set of sensors and a monitoring device. In the station control layer of the power station, a...
