Compared with the prior art, the surge protection device with the remote alarm function sends an alarm signal after being invalid and disconnected, so that wrong indications are prevented, and remote alarm can be realized; besides, the surge protection device has better safety and stability.
Description
Technical field
The utility model relates to the shocking preventing technology field, particularly a kind of surge protector that carries out remote alarms.
Background technology
Along with development of science and technology, the employed electric equipment of people is more and more, and its internal structure is also more and more accurate, responsive.But owing to reasons such as interfering with each other between the folding of power supply, in-plant thunderbolt, the electric equipment, surge often appears in the holding wire of electric equipment, promptly a kind of paroxysmal, hold time extremely short but the very high voltage of peak value.There is very big destructiveness in this high voltage for the components and parts of electric equipment.Therefore, people often adopt various types of surge protectors to come the electric equipment in the protection circuit.
Surge protector is a kind of low-voltage variation device commonly used; Under normal circumstances; It is in high impedance status, in case and circuit because of thunderbolt or other reason when surge occurring, its can conducting in the extremely short time; Lightning current or overvoltage are introduced the earth through earth connection, come the electric equipment on the protection circuit with this.When existing surge protector lost efficacy; The methods of onsite alarming that adopt pass to the external world with the information that surge protector lost efficacy more; The tripping mechanism of surge protector generally comprises dropout copper sheet, spring and indication slide plate, and spring is connected with the indication slide plate, props up spring after the copper pin welding of dropout copper sheet and chip varistor; When the copper sheet on the surge protector body is threaded off; Spring drives the indication slide plate slides under the effect of elastic force, the red zone on the indication slide plate is presented at display window, and the expression surge protector lost efficacy.But there is following defective in this mechanical indicating mode:
If spring is fused with the junction of indication slide plate, the surge protector indication that will make a mistake.
The utility model content
The utility model purpose is to provide a kind of surge protector that carries out remote alarms, is fused the technical matters that surge protector will make a mistake and indicate as if quilt with the spring of existing surge protector in the solution prior art and the junction of indication slide plate.
The novel purpose of this reality realizes through following technical scheme:
A kind of surge protector that carries out remote alarms comprises surge protection device and Failure Alarm device, and the Failure Alarm device comprises failure detection assembly and warning device, and the failure detection assembly is connected with warning device with surge protection device respectively.
Preferably; The chip varistor that surge protection device comprises binding post at least, is arranged on the lug plate on the binding post, the dropout copper sheet that is connected with lug plate, the dropout shell fragment that is connected with the dropout copper sheet are connected with leg with the dropout copper sheet, said dropout shell fragment is arranged on the below of said dropout copper sheet.
Preferably; The failure detection assembly comprises the pcb board that is connected with binding post and is arranged on the sensitive switch on the pcb board; Sensitive switch is arranged on the below of dropout copper sheet; One end butt of sensitive switch and said dropout shell fragment, the leg that the copper of chip varistor was worn pcb board and dropout copper sheet welds through the mode of low-melting alloy, and the binding post on the pcb board is connected with warning device.
Preferably, said warning device comprises microprocessor and long-distance alarm apparatus, and said microprocessor is connected with long-distance alarm apparatus with pcb board respectively.
Preferably, said warning device comprises the indicator light that is arranged on the surge protection device, and said indicator light is connected with binding post on the pcb board.
Compared with prior art, the utility model lost efficacy at surge protector and just sent alarm signal when breaking off, and can avoid sending wrong indication, and the real remote alarms of ability, had better fail safe and stability.
Description of drawings
Structural representation when Fig. 1 is the utility model operate as normal;
Fig. 2 is the structural representation under the utility model failure state.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1; The surge protector of the carried out remote alarms of the utility model; Comprise surge protection device and Failure Alarm device, the Failure Alarm device comprises failure detection assembly and warning device, and the failure detection assembly is connected with warning device with surge protection device respectively.
The chip varistor 15 that surge protection device comprises binding post 11 at least, is arranged on the lug plate 12 on the binding post 11, the dropout copper sheet 13 that is connected with lug plate 12, the dropout shell fragment 14 that is connected with dropout copper sheet 13 are connected with leg with dropout copper sheet 13, dropout shell fragment 14 is arranged on the below of dropout copper sheet 13.
The failure detection assembly comprises the pcb board 21 that is connected with binding post 11 and is arranged on the sensitive switch 22 on the pcb board 21; Sensitive switch 22 is arranged on the below of dropout copper sheet 13; One end butt of sensitive switch 22 and dropout shell fragment 14; The leg that the copper pin 151 of chip varistor 15 passes pcb board 21 and dropout copper sheet 13 welds through the mode of low-melting alloy, and the binding post on the pcb board 21 is connected with warning device.
Warning device comprises microprocessor and long-distance alarm apparatus, and microprocessor is connected with long-distance alarm apparatus with pcb board respectively.Warning device also comprises the indicator light that is arranged on the surge protection device, and indicator light is connected with binding post on the pcb board.
During operate as normal; Dropout copper sheet 13 is fixed on the brace 12 with dropout shell fragment 14 through screw, and the copper pin 151 of the leg of dropout copper sheet 13 and chip varistor 15 connects through the eutectic welding soldering, and dropout shell fragment 14 is pressed in dropout copper sheet 13 belows; One end of dropout shell fragment 14 props up sensitive switch 22; The contact of sensitive switch is opened, and circuit is disconnected, and sensitive switch is in normally off.When product failure, the low temperature tin of chip varistor 15 and dropout copper sheet 13 pads melts, and dropout copper sheet 13 is open under the elastic force effect of dropout shell fragment 14, thereby product gets into open-circuit condition.Simultaneously, because dropout shell fragment 14 automatically springs open, make sensitive switch 22 under the elastic force effect of contained spring, make the closing of contact, circuit is connected, thereby makes indicator light become redness by green, shows that product has been in failure state.Simultaneously, the signal that microprocessor is connected the sensitive switch circuit sends to long-distance alarm apparatus, makes long-distance alarm apparatus send alarm signal, so that the attendant safeguards this or changes.
The utility model lost efficacy at surge protector and just sent alarm signal when breaking off, and can avoid sending wrong indication, and the real remote alarms of ability, had better fail safe and stability.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
