Abstract
The utility model relates to a gas leakage and electrical fire alarm power-off device. The device comprises a smoke sensor. The smoke sensor is connected with an alarm device. When gas or smoke is detected by the smoke sensor, the chemical composition is converted into an electrical signal, and the electrical signal is amplified to drive the alarm device and an electromagnetic relay to work. The output end of the electromagnetic relay is connected with the input end of a relay normally open switch. The output end of the relay normally open switch is connected with a dummy load having a resistance value of 5 kilo-ohms, and then is connected with the output end zero wire and the output end live wire of a leakage protector. The leakage protector is connected with the household main power switch. When the gas or the smoke is detected, the relay normally open switch is closed to cause the short circuit of the leakage protector, that is, the household main power switch is disconnected. An indicating lamp is arranged on the smoke sensor. According to the device of the utility model, advantages of high sensitivity, low production cost and easy installation are realized, and the device can be popularized.
Description
Technical field
The utility model relates to a kind of protective device, relates to specifically a kind of gas leakage, the electric wire warning breaker device that cocks off.
Technical background
Gas pipeline wears out and is easy to produce gas leakage, and a large amount of carbon monoxide of gas leakage discharging is the root that combustion gas is poisoned, at this moment, if someone switch or Mars is arranged will produce spark, blast, produce fire, report to the police and breaker device if having, will avoid fire to occur; Also grow phenomenons such as seeing electric wire is aging, electric leakage in the family, all be easy to produce fire, if the device of the outage of reporting to the police is arranged, will reduce the loss of fire.
The utility model content
In order to address the above problem, the utility model provides a kind of warning breaker device, and this device is sensitive high, and cost of manufacture is low and be easy to installation, can generally promote the use of.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is a kind of gas leakage; the electric wire warning breaker device that cocks off; comprise Smoke Sensor; alarm; electromagnetic relay; Smoke Sensor and alarm link together; Smoke Sensor detects combustion gas or smog; chemical composition is converted into the signal of telecommunication; after amplifying, promote alarm and electromagnetic relay work; the output of electromagnetic relay is connected with a relay normally open switch input terminal; be connected with earth leakage protective device output live wire with the output zero line of an earth leakage protective device connect one 5 kilo-ohms dummy load at the output of relay normally open switch after; earth leakage protective device connects family's total power switch, and when Smoke Sensor detected combustion gas or smog, the relay normally open switch closed; cause the earth leakage protective device short circuit, can cut off family's total power switch.
Further improvement of the utility model is: also be provided with indicator light on Smoke Sensor, indicator light extinguishes, and described gas leakage, the electric wire warning breaker device that cocks off begins to enter normal operating state.
The beneficial effects of the utility model are: this device Smoke Sensor is examined the combustion gas signal can automatic alarm, and can automatically cut off earth leakage protective device total power switch in the family, prevents the fire that causes because of sparkover, reaches the purpose of protection family's property.If aging because of electric wire in the family, when electric leakage produces electric fire, smog is detected by Smoke Sensor, also can produce automatic alarm, and can automatically cut off earth leakage protective device total power switch in the family, avoids fire further to upgrade.This device is sensitive high, and cost of manufacture is low and be easy to installation, only needs two lines to receive in family's general supply box, just can cut off rapidly family's total power switch, can generally promote the use of.
