Provided is a circuit breaker case which can be reminded after long-time use. The electric heating device comprises a body, be equipped with reminding device on the body, reminding device includes timing device and warning light, the warning light is fixed on the body, just the warning light is got from the circuit, the warning light with be equipped with switch module between the circuit, timing device control switch module is closed or the disconnection. The timing device controls the switch component to be switched on or switched off. When the circuit breaker shell needs to be replaced, the prompting lamp is turned on for prompting a user to replace the circuit breaker shell.

Description

Breaker shell

Technical Field

The utility model relates to a power device especially relates to the improvement to the circuit breaker casing.

Background

The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. The circuit breaker divide into high voltage circuit breaker and low voltage circuit breaker according to its application range, no matter be high voltage circuit breaker or low voltage circuit breaker generally place the device of circuit breaker on insulating casing, the casing generally uses the bolt to fix and seals, seals the device of circuit breaker inside the casing, plays insulating effect, but the casing becomes fragile easily after long-time the use, leads to insulating properties to reduce, and because the casing outward appearance is not damaged, the user ignores easily, finally leads to the emergence of incident easily, and the security performance is poor.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a circuit breaker shell that can remind after long-time use.

The utility model discloses a following technical scheme realizes: the circuit breaker shell comprises a body, wherein a reminding device is arranged on the body and comprises a timing device and a prompting lamp, the prompting lamp is fixed on the body and is powered from a circuit, a switch assembly is arranged between the prompting lamp and the circuit, and the timing device controls the switch assembly to be closed or disconnected.

The switch assembly comprises a normally open contact and a control coil, the control coil is powered by a direct current power supply, and when the timing device finishes timing, the control coil is powered off, and the normally open contact is disconnected.

The timing device is provided with a controller, the controller receives signals of the timing device and sends instructions to disconnect the control coil, an electromagnetic switch is arranged between the control coil and the direct-current power supply, and the controller controls the on-off of the control coil through controlling the electromagnetic switch.

Compared with the prior art, the timing device controls the switch component to be closed or disconnected. When the circuit breaker shell needs to be replaced, the prompting lamp is turned on for prompting a user to replace the circuit breaker shell.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic circuit diagram of the present invention;

in the figure: 1. a body; 2. a warning light; 3. a normally open contact; 4. a control coil; 5. an electromagnetic switch; 6. and (4) resistance.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1, the circuit breaker casing comprises a body, a reminding device is arranged on the body, the reminding device comprises a timing device and a prompting lamp, the prompting lamp is fixed on the body and is powered from a circuit, a switch assembly is arranged between the prompting lamp and the circuit, and the timing device controls the switch assembly to be closed or disconnected. When the circuit breaker shell needs to be replaced, the prompting lamp is turned on for prompting a user to replace the circuit breaker shell.

The switch assembly comprises a normally open contact and a control coil, the control coil is powered by a direct current power supply, and when the timing device finishes timing, the control coil is powered off, and the normally open contact is disconnected. The timing device controls the switch component to be switched on or switched off. When the circuit breaker shell needs to be replaced, the prompting lamp is turned on for prompting a user to replace the circuit breaker shell. Because the resistance of the control coil is small, a resistor is connected in series in the power-on process to avoid short circuit of the circuit.

The timing device is provided with a controller, the controller receives signals of the timing device and sends instructions to disconnect the control coil, an electromagnetic switch is arranged between the control coil and the direct-current power supply, and the controller controls the on-off of the control coil through controlling the electromagnetic switch. The timing device controls the switch component to be switched on or switched off. When the circuit breaker shell needs to be replaced, the prompting lamp is turned on for prompting a user to replace the circuit breaker shell. The controller can be a PLC or a single chip microcomputer, and the controller which can receive timing ending signals of the timing device and send control instructions of the electromagnetic switch can be used for achieving the functions of the controller in the scheme.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
