Below in conjunction with accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.The assembly of the utility model embodiment describing and illustrate in usual accompanying drawing herein can be arranged with various different configuration and design.Therefore, below to the detailed description of the embodiment of the present utility model provided in the accompanying drawings and the claimed scope of the present utility model of not intended to be limiting, but selected embodiment of the present utility model is only represented.Based on embodiment of the present utility model, the every other embodiment that those skilled in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
At present, when the state of insulation of the insulating device to electric railway detects, the method used generally all needs insulating device to disassemble from installation site, or in insulating device position, special checkout equipment is installed, so just cause detection complex operation, the cost detected is high, inefficient problem.Based on this, the utility model provides a kind of state of insulation pick-up unit and system of insulating device, in the process can advanced at train in fact, to train process Along Railway in the state of insulation of insulating device detect, do not need insulating device to disassemble, more do not need for each section of railway track installs special checkout equipment, simple to operate, save cost, raise the efficiency.It should be noted that device provided by the utility model, not only can detect the insulating device in electric railway, the state of insulation of the insulating device in other field can also be detected.For ease of understanding the present embodiment, first the insulation state monitoring device of a kind of insulating device disclosed in the utility model embodiment is described in detail.
Shown in Figure 1, the insulation state monitoring device of insulating device provided by the utility model comprises: ultraviolet imagery device 20, data processor 10, state of insulation value comparer 30 and trigger 40;
Wherein, described ultraviolet imagery device 20 is connected with described data processor 10, gathers the information that insulating device outwards discharges ultraviolet light under different insulative state, and exports state of insulation information to described data processor 10;
Described data processor 10, comprises input interface 101, output interface 102 and internal calculator 103; Described internal calculator 103, according to described state of insulation information, calculates and generates state of insulation value; Described input interface 101 is connected with described ultraviolet imagery device 20, receives the described state of insulation information of described ultraviolet imagery device input; Described output interface 102 exports described state of insulation value to described comparer;
Described state of insulation value comparer 30 is connected with described trigger, determines whether to export minimum detectable signal to described trigger 40 according to the described state of insulation value received;
Described trigger 40 is alert trigger signal after the described minimum detectable signal of reception.
When specific implementation, due to the status information of insulating device outside release ultraviolet light under different insulative state that ultraviolet imagery device 20 gathers, be the photo of the ultraviolet light near the insulating device captured by ultraviolet imagery device actually.When insulating device because state of insulation is bad and when creating corona, corona position can send ultraviolet light, this ultraviolet light can capture by ultraviolet imagery device, in the photo captured by ultraviolet imagery device, show as hot spot, and there is no ultraviolet part, then show as dark.Hot spot is more large more, proves that the ultraviolet that insulating device produces due to corona is more, meanwhile, also proves that the state of insulation of insulating device is also all the more bad.
And the data processor 10 in the utility model includes internal calculator, by internal calculator, the photo captured by ultraviolet imagery device can be processed, the size of the hot spot in photo, quantity etc. are converted into corresponding state of insulation value, and export comparer to.
And in state of insulation value comparer 30, prestore state of insulation threshold value, this state of insulation threshold value is a threshold value of artificial setting, when state of insulation value exceeds this state of insulation threshold value time, just think that insulating device cannot meet insulation needs again, need to carry out changing (such as being changed by aging insulating device) or safeguarding (such as the insulating device that the state of insulation caused due to outside contamination changes being carried out pollutant cleaning etc.).
Such as in the utility model embodiment, HB-OPTICALUV type ultraviolet sight glass or Nature ultraviolet photography narrow-band-filter lens can be selected as ultraviolet optics form; Select FL-BC2528-VGUV camera lens as ultraviolet optics camera lens; Select ProxiVisionMCP day blind ultraviolet imaging enhancer as optical signalling conditioner; Select SonyXC-EU50 video camera as imaging device; Select Daheng's Channel Image capture card as image acquisition device.
The state of insulation pick-up unit of the insulating device that the utility model embodiment provides, because corona discharge is a kind of electric discharge phenomena of localization, when the local voltage stress of electrified body exceedes critical value, can make free of air and produce corona discharge phenomenon.Particularly high voltage electric power equip ment, it is often because of design, manufacture, installation and the bad generation corona of maintenance work, flashover or electric arc.In discharge process, the electronics in air constantly obtains and releases energy, and when electronics releases energy (namely discharging), just can release ultraviolet.If after insulating device generation corona, the ultraviolet of releasing just can be collected by ultraviolet imagery device 20, namely ultraviolet imagery device 20 can capture the information that insulating device outwards discharges ultraviolet light under different insulative state.And data processor 10 is after receiving this state of insulation information by input interface, calculates generation state of insulation value by internal calculator 103 according to this state of insulation information, and export in state of insulation value comparer 30 by output interface; Described state of insulation value and the state of insulation threshold value preset compare by state of insulation value comparer 30, and when state of insulation value exceeds default state of insulation threshold value, export minimum detectable signal, show that the insulating property of insulating device have reached the critical of needs maintenance.Trigger 40 after receiving this minimum detectable signal, alert trigger signal, thus staff according to alarm signal, can keep in repair corresponding insulating device or change.In this process, the insulation state monitoring device of insulating device is only needed to advance along electric railway, in the process of advancing, the state of insulation constantly going up each insulating device along the line for electric railway detects, do not need again as in the prior art, insulating device to be disassembled or for each insulating device installation detecting device, thus operation is simpler, cost is more saved, and the efficiency of detection is also higher.
Shown in Figure 2, the utility model embodiment provides a kind of ultraviolet imagery device.The ultraviolet imagery device 20 that the present embodiment provides comprises:

When specific implementation, the special wave band ultraviolet light outwards discharged under wanting to capture insulating device different insulative state, needs to use special ultraviolet optics camera lens 201.
And ultraviolet imager 202, then the ultraviolet light be used to ultraviolet optics camera lens 201 captures carries out imaging.
Preferably, in another embodiment of the present utility model, in ultraviolet imagery device, also comprise: optical signalling conditioner 203; Described optical signalling conditioner 203 is installed between described ultraviolet optics camera lens 201 and ultraviolet imager 202;
