Abstract

The invention provides an electric power maintenance voltage detector. The electric power maintenance voltage detector comprises a casing, a signal transceiver, a control interface and a standby power source alarm device, wherein the casing is arranged outside the control interface and an acquisition detection device, the signal transceiver is arranged at the upper side of the casing, the control interface is arranged at the lower side of the signal transceiver, the acquisition detection device is arranged at the lower side of the control interface, and the standby power source alarm device is arranged between the control interface and the signal transceiver. According to the electric power maintenance voltage detector, through setting the control interface, the acquisition detection device and the standby power source alarm device, the simple and rapid control and display device is realized, an operation process is simplified, work efficiency is improved, noise filtering and isolation protection functions for the detection voltage are realized, detection accuracy and protection performance are improved, timely alarm prompt for insufficient electricity quantity is facilitated, and safety monitoring performance is improved.

Description

technical field [0001] The invention belongs to the field of voltage detectors, in particular to a voltage detector for electric power maintenance. Background technique [0002] The voltage detector is a high-grade power grid voltage quality monitoring and statistics instrument. It can convert and process the read-in voltage signal. Under the synchronous control of the clock, it can automatically monitor, count and analyze various statistical values ​​and store them for users to choose. Readout can collect, display, and classify and count various voltage signals (PT output ~ 100V, 220V, 380V). It is one of the necessary means for power system monitoring and assessment of grid voltage quality. The existing electric maintenance voltage detector is cumbersome to operate, the detection voltage display is inaccurate, noise filtering and isolation protection cannot be performed on the detection voltage, and the safety is poor. At present, the existing electric power maintenance v...
