Abstract
The utility model relates to a multifunctional electric fire detector. The fire detector comprises a shell, and a control board, a current transformer, a residual current transformer, a power transformer, voltage transformers and a breaker all disposed in the shell. The output terminal of the current transformer, the output terminal of the residual current transformer, the output terminal of the power transformer and the output terminal of each voltage transformer are all connected to the input terminal of the control board. The output terminal of the control board is connected to the input terminal of the breaker. Electric leakage signals, overcurrent signals, overvoltage signals and under-voltage signals are detected by the multifunctional electric fire detector and are determined by the control board, then control signals are sent to drive the breaker powered off, so that multifunctional monitoring is achieved, the electrical fire is prevented totally, economy losses due to the electric fire are prevented, and therefore life safety and property safety of people are ensured.
Description
Technical field
The utility model relates to a kind of detector, particularly be a kind of multifunctional electric fire detector.
Background technology
China accounts for more than 30% of electrical fire because of electrical fire every year, and traditional electrical fire detector generally only has creepage protection function, can not the omnibearing protection electrical fire.
The utility model content
The purpose of this utility model is to provide a kind of multifunctional electric fire detector of realizing multifunctional monitoring.
The technical scheme that its technical matters that solves the utility model adopts is: the multifunctional electric fire detector, constituted by casing and control panel, current transformer, residual current transformer, power transformer, voltage transformer (VT) and the isolating switch of being located at casing inside, the output terminal of described current transformer, residual current transformer, power transformer, voltage transformer (VT) all is connected to the input end of control panel, and the output terminal of described control panel is connected to the input end of isolating switch.
Described casing is made up of upper casing and bottom, and the outside correspondence of described bottom is provided with two trapped orbits.
By adopting above-mentioned technical scheme; the beneficial effects of the utility model are: the utility model adopts signals such as detecting electric leakage, excess current, superpotential, under-voltage; after control panel is judged; send control signal; the outage of driving isolating switch realizes multifunctional monitoring, the omnibearing protection electrical fire; avoid because economic loss takes place electrical fire, thereby ensure people's security of the lives and property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, multifunctional electric fire detector of the present utility model, by casing 1 and the control panel 3 of being located at casing 1 inside, current transformer 4, residual current transformer 5, power transformer 6, voltage transformer (VT) 7 and isolating switch 8 constitute, described casing 1 is made up of upper casing 11 and bottom 12, the outside correspondence of described bottom 12 is provided with two trapped orbits 2, described current transformer 4, residual current transformer 5, power transformer 6, the output terminal of voltage transformer (VT) 7 all is connected to the input end of control panel 3, the output terminal of described control panel 3 is connected to the input end of isolating switch 8, and power transformer 6 provides working power for this machine.When protected circuit generation electric voltage exception, after voltage transformer (VT) 7 is gathered voltage signal, reach control panel 3, after control panel 3 internal circuits are judged, send power-off signal, make isolating switch 8 outages, and send sound and light alarm.When electric leakage takes place in protected circuit, gather electric leakage signal through residual current transformer 5, reach control panel 3, after control panel 3 internal circuits are judged, send power-off signal, make isolating switch 8 outages, and send sound and light alarm.Excessive when protected circuit load power consumption, gather overcurrent signal through current transformer 4, reach control panel 3, after control panel 3 internal circuits are judged, send power-off signal, make isolating switch 8 outages, and send sound and light alarm.Realize multifunctional monitoring, omnibearing protection is avoided the generation of electrical fire, thereby ensures people's security of the lives and property.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
