Abstract

The invention discloses an on-line teletransmission display and alarm device for power operation equipment. The device comprises a high-voltage inductive type sensor device, a high-voltage charged display device, a display and alarm terminal and a wireless transmission device, wherein the high-voltage inductive type sensor device and the high-voltage charged display device are arranged at a transformer substation end; the display and alarm terminal is arranged at a local end; the wireless transmission device is arranged between the transformer substation end and the terminal; and the high-voltage inductive type sensor device, the high-voltage charged display device, the wireless transmission device and the display and alarm terminal are sequentially connected. According to the on-line teletransmission display and alarm device for power operation equipment, defects of small monitoring range, low reliability, poor accuracy and the like in the prior art can be overcome, so that the advantages of large monitoring range, high reliability and good accuracy can be realized.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an online remote transmission display and alarm device for electric power operation equipment. Background technique [0002] As a device that can convert invisible high-voltage electrical signals into visible light signals and reflect the charging status of high-voltage equipment, the high-voltage live display device has been widely used in the power industry. [0003] The high-voltage charged display device can transmit the signal of whether the high-voltage charged body is charged or not to the luminous or sound element, display or block the high-voltage switchgear at the same time, including two parts of the sensor and the display. [0004] The high-voltage charged display device detects the output signal of the sensor, and displays the charging status in the form of light-emitting devices or sound components after processing. Its appearance solves the problem...
