Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Be illustrated in figure 2 the structural representation of a kind of Surge Protector lightning protection box of the utility model monitoring device, interior lightning-protection module 11 and the isolating switch 12 of arranging of described Surge Protector lightning protection box 1, described lightning-protection module 11 is connected by phase line 13 with isolating switch 12, comprising:
The parameter acquisition module 21 of the running parameter of described phase line 13 is set and gathers near described phase line 13;
Be connected with described parameter acquisition module 21, and the data storage processing module 22 of the running parameter of the described phase line 13 that described in stores processor, parameter acquisition module 21 gathers;
Be connected with described data storage processing module 22, according to the control of described data processing module 22, the running parameter of the described phase line 13 through described data storage processing module 22 stores processor is sent to the radio-frequency (RF) receiving and transmission module 23 that client shows by RF-wise.
By radio-frequency (RF) receiving and transmission module 23, the running parameter of phase line 13 is sent to client, because phase line 13 connects lightning-protection module 11 and isolating switch 12, so the duty of lightning protection box, the duty of lightning-protection module 11, is reflected in phase line 13 completely.Therefore patrol officer is without the duty of climbing up electric pole high more than 3 meters and removing to observe lightning protection box, running parameter by the phase line 13 obtained just can be understood the duty of lightning protection box, thereby greatly improve polling rate, also can more easily find the lightning protection box breaking down.Simultaneously, in some region, enter the region that lightning protection box is set, need to pass through multiple formality, and the utility model is owing to having adopted RF-wise to send the running parameter of phase line 13, therefore can near lightning protection box, can obtain the running parameter of phase line 13, thereby understand the duty of lightning protection box.
Parameter acquisition module 21 can adopt different acquisition modules according to the difference of the running parameter of the phase line 13 that will gather.For example, if gather the voltage of phase line 13, can adopt voltage table, near and the voltage that obtains phase line 13 in parallel with phase line 13, or if gather the current value of phase line 13, can adopt reometer, near and connect and obtain the electric current of phase line 13 with phase line 13, or if gather the electromagnetic radiation of phase line 13, also can adopt electromagnetic radiation acquisition device, near but do not contact the electromagnetic radiation value that phase line 13 is obtained phase line 13.
In an embodiment, described parameter acquisition module 21 is close and does not contact the electromagnetic field acquisition module that described phase line 13 arranged and gathered the electromagnetic field value of described phase line 13 therein.Preferably, electromagnetic field acquisition module can adopt emf sensor.Because thunder and lightning has the characteristic of high voltage, large electric current, therefore, if adopt voltage table or reometer to measure voltage or the electric current of phase line 13, need to adopt voltage table or the reometer of anti-high pressure Chinese People's Anti-Japanese Military and Political College electric current, cost is very high.Adopt electromagnetic field acquisition module without contact with phase line 13, only needing can be without contact phase line 13 near phase line 13, so it is without anti-high pressure and electric current greatly.Described near and do not contact phase line 13 and refer in the measurable range generating an electromagnetic field in phase line 13, concrete distance specifically arranges according to the running parameter of adopted electromagnetic field acquisition module.Preferably, because electromagnetic field is around phase line 13, so electromagnetic field acquisition module can adopt the mode around phase line 13 to design.
In an embodiment, if the electromagnetic field value of the described phase line of described data storage processing module surpasses default leakage current electromagnetic field threshold value, by described radio-frequency (RF) receiving and transmission module, send to described client therein.The components and parts of lightning-protection module 11 inside can be lossy, likely in critical point deteriorated or that lost efficacy, its display form for producing leakage current in phase line 13, this leakage current can produce corresponding electromagnetic field, therefore, can calculate the leakage current producing when deteriorated or critical point that lost efficacy, and calculate the electromagnetic field value that this leakage current produces, as leakage current electromagnetic field threshold value.By the electromagnetic field value of phase line 13 is monitored, when the electromagnetic field value of phase line 13 surpasses default leakage current electromagnetic field threshold value, can judge that the components and parts of lightning-protection module 11 inside are in critical point deteriorated or that lost efficacy, thereby by radio-frequency (RF) receiving and transmission module, send to client, notice is used the patrol officer of client.
Therein in an embodiment, described data storage processing module is added up number of times that the electromagnetic field value of described phase line surpasses default Lightning Electromagnetic Fields threshold value as number of lightning strokes, and described number of lightning strokes is sent to described client by described radio-frequency (RF) receiving and transmission module.During due to thunderbolt, phase line 13 can produce large electric current, produce corresponding electromagnetic field simultaneously, the electromagnetic field value that during thunderbolt, phase line 13 forms can be far longer than the electromagnetic field value while not being struck by lightning at ordinary times, by a default Lightning Electromagnetic Fields threshold value, when monitor over Lightning Electromagnetic Fields threshold value electromagnetic field value time, can judge the event of being once struck by lightning that produced, statistics sends the number of times of thunderbolt event and sends to client, and patrol officer can determine that this lightning-protection module 11 stands the number of times of the event of being struck by lightning.The number of times that lightning-protection module 11 stands thunderbolt is conditional, and too much when number of lightning strokes, the components and parts of lightning-protection module 11 inside have larger loss, and after reaching certain number of times, lightning-protection module 11 must be changed.The present embodiment surpasses the number of times of the electromagnetic field value of Lightning Electromagnetic Fields threshold value by statistics, thereby determines the number of lightning strokes that lightning-protection module 11 stands, and sends to client by RF-wise.Without the actual contact of patrol officer lightning protection box, can determine the number of lightning strokes of lightning protection box, greatly improved and patrolled and examined efficiency, also avoided the lightning-protection module 11 of lightning protection box 1 due to the number of lightning strokes potential safety hazard that too much inefficacy brings.
In an embodiment, also comprise analog-to-digital conversion module 24 therein, described parameter acquisition module 21 is connected with described data storage processing module 22 by analog-to-digital conversion module 24.
