Abstract
The utility model relates to a monitoring alarm device for examineing and repair case or power supply case, it is including setting up at the current transformer TA by on the observation circuit, fuse FU, emitting diode VD1, emitting diode VD2, switch SB1, switch SB2, temperature -sensitive switch CD, loudspeaker CF1 and loudspeaker CF2, current transformer TA, switch SB1, fuse FU and emitting diode VD1 establish ties in proper order, and switch SB2 and loudspeaker CF1 establish ties into first branch road, and temperature -sensitive switch CD, loudspeaker CF2 and emitting diode VD2 establish ties into the second branch road, first branch road, second branch road connect in parallel respectively at emitting diode VD1's both ends, the utility model provides high electrical safety nature, can effectively monitor the power consumption state, can remind maintainer load high temperature, in time the check -out set prevents to burn out, the utility model discloses the cost is cheap, convenient to use, safe and reliable.
Description
Technical field
The utility model relates to a kind of monitoring device for station case or electrical source of power case air-break, particularly relates to the monitoring alarm for service chamber or electrical source of power case.
Background technology
In the service chamber of transformer station or electrical source of power case, air-break is more, whether have electric current in which air-break corresponding, whether transship, whether loose contact or temperature whether too high, lack and detect effectively intuitively or the means of supervision, general at present a pilot lamp is connected to air-break end opening, when air-break closes a floodgate, pilot lamp is bright, and the method can only instructed voltage be closed a floodgate, and cannot effectively monitor its electric current and state of temperature.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safe and reliable, effective monitoring electricity condition, improves safety guarantee and the monitoring alarm for service chamber or electrical source of power case preventing air-break from burning.
The technical solution of the utility model is as follows:
The utility model comprises the current transformer TA be arranged on monitored circuit, fuse FU, light emitting diode VD1, light emitting diode VD2, switch S B1, switch S B2, temperature-sensitive switch CD, loudspeaker CF1 and loudspeaker CF2; Current transformer TA, switch S B1, fuse FU and light emitting diode VD1 connect successively; The first branch road and the second branch road is parallel with at the two ends of light emitting diode VD1, first branch road and the second branch circuit parallel connection, described first branch road comprises switch S B2 and the loudspeaker CF1 of series connection, and described second branch road comprises the temperature-sensitive switch CD, loudspeaker CF2 and the light emitting diode VD2 that connect successively.
Further, described temperature-sensitive switch CD set temperature is 65 DEG C, and described current transformer TA mutual inductance ratio is 100:1.
The beneficial effects of the utility model are as follows:
1) the utility model improves electrical safety by arranging current transformer TA;
2) by light emitting diode VD1 effectively monitoring electricity condition, reported to the police by loudspeaker CF1, improve electrical safety further;
3) maintainer's load temperature can be reminded too high by arranging thermoswitch CD, light emitting diode VD2 and loudspeaker CF2, timely checkout facility, prevents from burning electrical part;
4) the utility model low cost, easy to use, safe and reliable, is applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is circuit connection diagram of the present utility model.
Embodiment
As shown in Figure 1: the utility model comprises the current transformer TA be arranged on monitored circuit, fuse FU, light emitting diode VD1, light emitting diode VD2, switch S B1, switch S B2, temperature-sensitive switch CD, loudspeaker CF1 and loudspeaker CF2; Current transformer TA, switch S B1, fuse FU and light emitting diode VD1 connect successively, switch S B2 and loudspeaker CF1 is connected into the first branch road, temperature-sensitive switch CD, loudspeaker CF2 and light emitting diode VD2 are connected into the second branch road, and described first branch road, the second branch road are connected in parallel on the two ends of light emitting diode VD1 respectively.Preferred described temperature-sensitive switch CD set temperature is 65 DEG C, and described current transformer TA mutual inductance ratio is 100:1.
During use, when main circuit has electric current time, light emitting diode VD1 is luminous, and during maintenance, by closed SB2, can prevent maloperation, when main circuit has electricity, loudspeaker CF1 jingle bell, can play alarm function, has prevented people's maloperation from getting an electric shock; When temperature is too high, thermoswitch CD closes, and light-emitting diodes VD2 is luminous, and loudspeaker CF2 jingle bell is reported to the police, thus improves security.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
