Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Trip protection device of the present utility model comprises protection loop and indicating device as shown in Figure 1.Protection loop; protection loop comprise for detection of the information of needs tripping operations and after the information that needs tripping operation detected, send trigger impulse protective device 1, be used for controlling the protection pressing plate 2 of protection loop break-make and receiving the breaking coil 3 disconnecting after the trigger impulse of protective device 1, protective device 1, protect pressing plate 2 and breaking coil 3 to connect.Indicating device, one end of indicating device is connected between protective device 1 and protection pressing plate, and breaking coil 3, protection pressing plate 2 and indicating device form series loop.
Breaking coil 3, protection pressing plate 2 and indicating device are the part that composition is used to indicate the indication loop that comprises pressing plate state.In the time detecting the state of protection pressing plate 2, by being added on indication loop of power supply, breaking coil 3, protection pressing plate 2, indicating device become series loop with power pack.If protection pressing plate is in connected state, the photodiode light of indicating device is with the state of indication protection pressing plate.
The trip protection device of the present embodiment comprises the indicating device for showing the state of protecting pressing plate 2.After switching on power, indicating device indicated number protection pressing plate 2 is in input state or in exit status.
Preferably, indicating device 4 also comprises the switch 5 of connecting with indicating device 41.
Indicating device 41 can be preferably electroluminescent lamp.In the time detecting the state of protection pressing plate 2, close a switch 5, if protect pressing plate 2 in input state, electroluminescent lamp is luminous; If protection pressing plate 2 is in exit status, electroluminescent lamp is not luminous.
The divider resistance 42 that the indicating device of the present embodiment comprises light-emitting diode and connects with light-emitting diode.Divider resistance 42 plays the effect of protection light-emitting diode.Light-emitting diode long service life and saves energy.
The present embodiment has been realized following technique effect as can be seen from the above description: be failure to actuate in the protection loop that uses the state of indicating device indication protection pressing plate to avoid the loose contact of protection pressing plate to cause.Further, indicating device is light-emitting diode, has improved the durability of trip protection device.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
