Abstract
The utility model relates to an over-current protection alarm device, particularly a safety protection current limiting alarm device, which comprises a signal launching device and a signal receiving device which is matched with the signal launching device. The power end of the signal launching device is connected in parallel with a heat sensitive sensor with a bimetallic strip and an electrical heating element which is connected in parallel with the heat sensitive sensor. The utility model has the functions of automatic over-current protection, automatic recovery and remote alarm.
Description
Technical field
The utility model relates to a kind of overcurrent protection warning device, is a kind of safeguard protection current limliting warning device specifically.
Background technology
At present; using electricity system all inserts electric terminal with socket or lead mode; in case be short-circuited; phenomenons such as overload; still can't protect and recovery voluntarily; more can't report to the police; the fire proportion that general electrical appliance and lead cause is bigger; because the equal unprotect measures of phenomenon such as instantaneous short circuit overload flow of electrical appliance promptly blow a fuse, and also need people to change; be the wasting manpower and material resources; also can't the localization of faults, bring very big inconvenience for people's daily life, bring great loss for country and individual.Particularly under unserviced situation, if long-time short circuit, easier the resulting in greater loss of overload,
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, safeguard protection current limliting warning device with overcurrent protection and long-distance alarm function.
For achieving the above object, the utility model adopts following technical scheme:
Safeguard protection current limliting warning device described in the utility model comprise sender unit and with the matching used signal receiving device of sender unit, the power end of sender unit is parallel with bimetallic strip heat sensitive sensor and the heating in parallel with the bimetallic strip heat sensitive sensor.
Above-mentioned heating can adopt the spiral electrothermal tube.
Bimetallic strip heat sensitive sensor and heating are fixedly mounted in the airtight container, and the bimetallic strip heat sensitive sensor is positioned at the top of heating.
The utlity model has following advantage after the employing technique scheme:
1) has overcurrent protection function,, can cut off the electricity supply automatically, try to avert accidents in case electric current is excessive;
2) have the long-distance alarm function, launch alerting signal by sender unit to signal receiving device in overcurrent protection, the staff can learn the working condition of circuit in the very first time.
3) have auto restore facility, after fault was got rid of, circuit can be resumed work automatically.
4) energy savings, circuit working just often sender unit are not worked, and only sender unit is just worked when over current fault takes place.
Description of drawings
Accompanying drawing is the circuit theory diagrams of an embodiment of the present utility model.
Embodiment
As shown in drawings; safeguard protection current limliting warning device described in the utility model; safeguard protection current limliting warning device; comprise sender unit 1 and with sender unit 1 matching used signal receiving device, the heating 4 that the power end of sender unit 1 is parallel with bimetallic strip heat sensitive sensor 3 and connects with bimetallic strip heat sensitive sensor 3.Have bimetallic strip heat sensitive sensor 3 and heating 4 to be fixedly mounted in the airtight container, bimetallic strip heat sensitive sensor 3 is positioned at the top of heating 4.Heating 4 can adopt the spiral electrothermal tube, also can adopt other electric heating forms.Form an overcurrent and system for detecting temperature by bimetallic strip heat sensitive sensor 3 and heating 4, the warning system of forming by sender unit 1 and signal receiving device.Under normal condition, bimetallic strip heat sensitive sensor 3 is equivalent to conductor, because the little working stability of contact resistance, power consumption is little, and sender unit 1 is not worked.When circuit terminal overload or temperature rising, heating 4 temperature raise, bimetallic strip heat sensitive sensor 3 is heated the back except that the some disconnection, use down circuitry, because the variation of bimetallic strip heat sensitive sensor 3 is in the power end generation voltage of sender unit 1, sender unit 1 work, fault-signal is sent, and onsite alarming.After fault was got rid of, when heating 4 was reduced to reset temperature, bimetallic strip heat sensitive sensor 3 resetted, its contact auto-closing, and circuit is connected.Signal receiving device is used for receiving the fault-signal of trouble spot and also prints by computer stored, and data are sent to administrative center.
The onsite alarming function: when the contact of bimetallic strip heat sensitive sensor 3 disconnected, the acousto-optic device of sender unit 1 started, thereby realized the onsite alarming function.
The utility model utilizes overcurrent temperature protection and emission to receive warning device, can be at any time with the phenomenon of the failure auto-cutout of electric terminal, and send to receiving terminal, in case break down, in time notify administrative center.In case after fault was got rid of, device automatically reset, the fire that takes place because of the circuit overcurrent and the loss of electrical appliance fault have effectively been prevented.Because automatically reseting of device significantly reduced staff's labour intensity.The onsite alarming function is in time handled the field staff, has avoided the expansion of accident.Used electric terminal is played protection and metering function, be specially adapted to industry, commerce, family, traffic, reach industry-by-industry.
Bimetallic strip heat sensitive sensor 3 and heating 4 no longer are described in detail at this for existing known technology.
