Problems solved by technology

[0003] The overvoltage protector in the prior art relies on the tripper to play a warning role, and reminds the staff when they are overhauling. This alarm method has low reliability and requires the staff to carry out close inspection of the overvoltage protectors one by one. Only then can it be found that the inefficiency

Embodiment 1

[0031] Such as figure 1 -As shown in Fig. 2, an overvoltage protector with a remote fault alarm device includes an overvoltage protector, the overvoltage protector includes a housing 1, and the exterior of the housing 1 is coated with an insulating layer 101, so The inside of the casing 1 is provided with an overvoltage protection mechanism and a tripping mechanism, the overvoltage protection mechanism includes a plurality of stacked resistance sheets 2, the top of the resistance sheet 2 is provided with an upper electrode 3, and the bottom is provided with a lower electrode 4;

[0032] The tripping mechanism includes a pull rod 5, a sliding seat 6 and a spring 7. The top of the pull rod 5 is inserted into the center of the lower electrode 4. The center of the lower electrode 4 is provided with a circular groove, and the center of the circular groove is provided with a gap fit with the pull rod 5. The through hole, the top of the pull rod 5 is inserted into the circular groove...

Embodiment 2

[0045] Such as image 3As shown, on the basis of Embodiment 1, the bottom of the paint box 11 is provided with a fault information collection module 21, and the fault information collection module 21 includes a normally closed reed switch and a permanent magnet, and the permanent magnet is fixedly connected to the bottom of the paint box 11. The closed reed switch is provided in the shell of the acquisition module. When the sliding seat 6 descends, it will drive the lower lead-out electrode column 10 to descend, drive the shell of the information collection module to descend, separate the normally closed reed switch from the permanent magnet, and conduct the circuit to collect the fault signal.

Embodiment 3

[0047] Such as Figure 4 As shown, on the basis of Embodiment 2, the fault information collection module 21 is connected to the remote alarm module 31, the remote alarm module 31 is fixedly installed on the insulating support 14, the remote alarm module 31 includes a GPRS communication module and an antenna, and the GPRS communication module is connected to a failure The signal acquisition device, the antenna, and the reed switch conduction circuit make the GPRS communication module start to work, and send signals to the host computer through GPRS communication.

[0048] Further, the remote alarm module 31 is provided with a power supply inside, and the power supply may be a rechargeable battery, and the rechargeable battery is connected to the solar panel on the shell of the remote alarm module 31 through the charging circuit module. Power is supplied by solar panels, and the power supply can be directly connected to the GPRS communication module through a normally closed dry...

Abstract

The invention relates to an overvoltage protector with a remote fault alarm device. There is an overvoltage protection mechanism and a tripping mechanism. The tripping mechanism includes a pull rod, a sliding seat and a spring; a display alarm mechanism is provided at the bottom of the housing, and the display alarm mechanism includes a paint box. There is a through hole in the gap between the electrode columns. There is a piston in the paint box. The paint box below the piston is filled with reflective paint. There is an L-shaped nozzle on the outside of the paint box. One end of the nozzle is connected to the inside of the paint box, and the other end There is an outlet facing upwards, and the outlet is covered with plastic film; the tripping mechanism of the overvoltage protector with remote fault alarm device is connected to the paint box, and the tripping mechanism can spray paint after the tripping mechanism is activated to make the overvoltage protector into a reflective Body, easy maintenance personnel maintenance, worthy of vigorous promotion.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an overvoltage protector with a remote fault alarm device. Background technique [0002] The overvoltage protector is an electrical product used to protect various electrical equipment in the power system from overvoltage damage, and has good protection performance. Because the nonlinear volt-ampere characteristics of the zinc oxide valve is very good, only a few hundred microamps of current flow through under the normal working voltage, which is convenient to design into a gapless structure, so that it has good protection performance, light weight and small size. feature. When the overvoltage invades, the current flowing through the valve increases rapidly, and at the same time limits the amplitude of the overvoltage and releases the energy of the overvoltage. After that, the zinc oxide valve returns to the high-resistance state to make the power system...
