Automatic alarm heater monitoring device

Abstract

The invention relates to a monitoring device, and particularly relates to an automatic alarm heater monitoring device. The characteristics lie in that the automatic alarm heater monitoring device comprises a shell and a sliding slot arranged on the shell, wherein the internal part of the shell is provided with a reflection device and an induction device which are connected by a wire, a buckling device is arranged in the sliding slot, the internal part of the shell is provided with an alarm device, the buckling device comprises spring bases, sliding blocks and springs at the internal edges of the shell, each spring base is provided with a groove corresponding to the bottom of the spring, the upper end of each spring is provided with a spring positioning block, the lower end of each spring positioning block is provided with a cylindrical hole matched with a positioning column, and one end of each sliding block is provided with a buckle; the reflection device comprises a reflective film installed at the top end of the shell and at least two indicator lights; and the induction device comprises a closed-loop coil wound with a wire and a current carrying wire passing through the closed-loop coil, and the alarm device comprises an inverter, a buzzer, an external power supply and a switch. The automatic alarm heater monitoring device has the beneficial effects of being capable of enabling the indicating effect to be more visual and more reliable and enabling the installation to be more convenient and firmer.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an automatic alarm heater monitoring device. Background technique [0002] Switchgear plays the role of control and protection in the power system, and is a common power equipment for power distribution network and substation functions. The reliable operation of the switchgear plays a vital role in the operation of the power grid and the safety of electricity. In the rainy season in the south, the rainfall is large, the rainfall lasts for a long time, and the air humidity is high, which will easily cause moisture condensation on the insulating parts and conductive surfaces of the switch cabinet, and easily lead to creepage and flashover accidents; and when the switch operating mechanism and opening and closing coils are damp. It often leads to the switch's refusal to open and close, causing equipment and power grid accidents. Timely and effective measures need to be taken to solve the prob...

AI Technical Summary

Problems solved by technology

[0004] (1) The rated current of the indicator light is 1-10A, the current is too high, the brightness of the indicator light is low, and the indication effect is not obvious;

[0005] (2) If multiple winding wires are used to increase the transformation ratio to increase the current indicated by the monitor, the winding is cumbersome;

[0006] (3) If the indicator is installed on the terminal block, there is no fixing measure, it is easy to slip, and it is not safe;

[0007] (4) The conductor crosses horizontally, the wiring is messy, not beautiful enough, and does not meet the lean requirements

[0008] (5) The reliability of the alarm is not high only by relying on the diode to emit light or not

However, there are problems in this patent that the reliability of the alarm is not high only by relying on the diode to emit light. If the indicator is installed on the terminal block, there is no fixing measure, it is easy to slip, and it is not safe.
