Problems solved by technology

[0004] However, the existing automatic reclosing protection switch cannot immediately cut off the on-site power supply when a fire occurs, resulting in a short circuit of the power line at the incident site, which expands the fire accident and causes greater loss of property and life. The performance needs to be further improved.
In an emergency, when a fire occurs at the initial stage, there is no quick emergency measure, and the power supply of the automatic reclosing protection switch is cut off immediately, which is not flexible and convenient to use

Embodiment 1

[0034] Such as figure 1 As shown, the automatic reclosing protection switch with fire alarm protection function of the present invention includes an automatic reclosing protection switch, a temperature detection unit and a wired or wireless remote alarm device, and the incoming line side of the power line is connected to the automatic reclosing protection switch. On the incoming line side, the outgoing line side of the automatic reclosing protection switch supplies power to the load. The temperature detection unit detects the ambient temperature. When the ambient temperature exceeds the set value, the temperature detection unit outputs an alarm signal to trigger the automatic reclosing protection switch and wired or wireless remote control. The alarm device operates, the automatic reclosing protection switch operates to cut off the power supply, and the wired or wireless remote alarm device starts to send out an alarm signal.

[0035] The above-mentioned emergency power-off sw...

Embodiment 2

[0050] Such as Figure 5 As shown, the principles of this embodiment and Embodiment 1 are basically the same, the difference is that: the temperature detection unit outputs an alarm signal directly to the input terminal of the automatic reclosing protection switch, and then the automatic reclosing protection switch sends the alarm signal Transfer to the wired or wireless remote alarm device and on-site sound alarm, the automatic reclosing protection switch acts to cut off the power supply, and the wired or wireless remote alarm device starts to send out an alarm signal. The on-site sound alarm emits a high-decibel alarm sound. The temperature detection unit triggers the automatic wired or wireless remote alarm device and the on-site sound alarm is indirectly triggered.

Embodiment 3

[0052] Such as Image 6 As shown, the principle of this embodiment is basically the same as that of Embodiment 1, the difference is that the temperature detection unit outputs an alarm signal directly to the input terminal of the wired or wireless remote alarm device, and then the alarm signal is forwarded by the automatic reclosing protection switch For the automatic reclosing protection switch and the on-site sound alarm, the automatic reclosing protection switch acts to cut off the power supply, and the wired or wireless remote alarm device starts to send out an alarm signal. The on-site sound alarm emits a high-decibel alarm sound. The temperature detection unit triggers the automatic reclosing protection switch and the on-site sound alarm is triggered indirectly.

Abstract

The invention relates to an automatic reclosing protection switch with a fire alarm protection function. The characteristics lie in that the automatic reclosing protection switch with a fire alarm protection function comprises an automatic reclosing protection switch and a temperature detection unit, an inlet side of a power supply line is connected to an inlet side of the automatic reclosing protection switch, an outlet side of the automatic reclosing protection switch provides power for a load, the temperature detection unit detects the temperature of the surrounding environment, the temperature detection unit outputs an alarm signal when the temperature of the surrounding environment exceeds a set value so as to trigger the automatic reclosing protection switch to operate, and the automatic reclosing protection switch operates to cut off power supply. The automatic reclosing protection switch is complete in function, can report fire alarm information effectively, timely and accurately, and automatically cuts off a power line at the scene of an accident to prevent expanding of the accident, thereby minimizing the loss, and guaranteeing the life and property safety of people.

Description

technical field [0001] The invention relates to an automatic reclosing protection switch with fire alarm protection function. [0002] Background technique: [0003] The automatic reclosing protection switch is applied in the circuit and can play a certain protective role, for example, it can protect the short circuit, severe overload and undervoltage of the circuit or electrical equipment. Existing automatic reclosing protection switches (such as air switches), in addition to functions such as leakage protection, short circuit protection, voltage loss protection, and overcurrent protection, can also automatically detect phase loss and phase failure, and realize automatic tripping , play a protective role. [0004] However, the existing automatic reclosing protection switch cannot immediately cut off the on-site power supply when a fire occurs, resulting in a short circuit of the power line at the incident site, which expands the fire accident and causes greater loss of prop...
