Description
Technical field
The utility model relates to field of electric automatization equipment, particularly automatic fuse.
Background technology
Fuse refers to when electric current exceedes setting, with the heat that itself produces, melt is fused, a kind of electrical equipment of open circuit.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.At present, its function of the fuse on market promptly can only to fuse process to circuit dangerous situation, cannot report to the police to dangerous situation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of by setting up alarm, and report to the police to dangerous situation while circuit fuses automatically, the automatic fuse that staff is removed the dangerous condition in time, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of fuse automatically, comprise outlet terminal, vacuum interrupter, alarm, conductive clip, pull bar, spring, drag link sleeve, fixed frame, current transformer, lower wire end, lead collar and sleeve, conductive clip is arranged on the lower end of arc control device, pull bar one end is arranged on conductive clip, one end is arranged on spring, the spring other end is arranged on drag link sleeve, the bottom of drag link sleeve is arranged in fixed frame, above structure is all wrapped up and is arranged in sleeve, upper outlet terminal is arranged on the top of sleeve, current transformer is arranged on the left side of sleeve, lower wire end is arranged on the left side on current transformer, lead collar is arranged on the lower end of current transformer, alarm is arranged on the right side of sleeve.
Preferably, described sleeve is outside equipped with silica gel sheath, and described fixed frame is provided with voltameter.
Preferably, described upper outlet terminal and lower wire end are provided with insulating case.
Preferably, described alarm, comprises body, warning lamp and buzzer, and buzzer is arranged on the inside of body, and warning lamp is arranged on the outer surface of body.
Adopt the beneficial effect of above technical scheme to be: the automatic fuse of the utility model structure, by setting up alarm, while circuit fuses automatically, dangerous situation is reported to the police, staff is removed the dangerous condition in time; Sleeve is outside equipped with silica gel sheath, and silica gel sheath can play insulating effect, fuse can being prevented there is electric shock accidents with during human contact, can also play the effect of protection sleeve simultaneously; Upper outlet terminal and lower wire end are provided with insulating case, and upper and lower outlet terminal is the interface of fuse place in circuit, therefore in order to prevent outlet electric leakage electric shock accident, sets up on its surface the effect that insulating case can be good at playing insulation protection; Fixed frame is provided with voltameter, voltameter set up by fuse, can indicate the power consumption of circuit, expand the function of fuse; Alarm, comprises body, warning lamp and buzzer, and buzzer is arranged on the inside of body, warning lamp is arranged on the outer surface of body, by such structure, when fuse automatic shutoff circuit, alarm just can carry out light warning and acoustic alarm, helps staff to understand dangerous situation in time.
