Multistage lightning protection device is equipped with usually in supply line in building, and dispersion is compared in installation site.But existing surge protector function singleness; do not possess telecommunications functions; information network can not be formed monitor in real time surge protector everywhere; the operating state of at-once monitor lightning protection device can not be joined; when lightning protection device occurs easily to produce the consequences such as short circuit accident when losing efficacy; need the running status regularly checking lightning protection device to erecting bed to attendant, bring inconvenience to operation maintenance work.
Existing surge protector adopts the number of lightning strokes of the mode of simple thunder-and-lightning counter to surge protector to add up usually; but amplitude and the waveform that can not analyze lightning current carry out Measurement and analysis; can not detailed data be put forward to the statistical analysis of locality thunderbolt present situation, scientific basis can not be provided for the thunder and lightning mitigation of locality.
Utility model content
For the problems referred to above; the utility model provides a kind of self-shield surge protector; this surge protector mainly comprises lightning current protection part and lightning current detects two large divisions; intelligent network is realized to surge protector; the running status of surge protection is monitored in real time, and provides the Monitoring Data of detailed science for local lightning protection mitigation work.
The technical solution of the utility model is as follows: a kind of self-shield surge protector, comprises air circuit, connects wire, thunder-and-lightning counter and working station indicator, lightning stream testing apparatus, surge protector, transducer, communication port, earthing device;
Described surge protector one end is connected on the power line by described air circuit; the other end is connected on described earthing device; described lightning stream testing apparatus is connected between described surge protector and described earthing device, described lightning stream testing apparatus is connected to simultaneously described thunder-and-lightning counter and working station indicator and described communication port.
Further, described lightning stream testing apparatus comprises: power interface, RS485 communication interface, lightning protection device state input interface, change send signal output interface, sensor interface, lighting current sensor, sensor connect lines and internal circuit to form.
Surge protector carries hot dropout modular lightning protection component, has from electricity-saving function, thunder-and-lightning counter, Remote, 485 communication functions and networking function, warning function, automatically detects lightning current size and lightning current waveform, records simultaneously and upload to host computer,
The utility model is by 485 bus communication modes; the surge protector in the same area can be allowed to form network, in the operating state of each surge protector of backstage Real-Time Monitoring, the surge protector lost efficacy is changed in time; prevent the generation of lightning strike accident, alleviate the working strength of attendant.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, self-shield surge protector of the present utility model, comprise air circuit 1, connect wire 2 (L1, L2, L3, N), thunder-and-lightning counter and working station indicator 3, lightning stream testing apparatus 4, surge protector 5, transducer 6,485 communication port 7, earthing device 8;
When supply line there being lightning current, lightning current can be released over the ground by surge protector 5.The transducer 6 pairs of thunders and lightnings be arranged on bleed-off circuit sample; and the parameter of lightning current is sent into the lightning stream testing apparatus 4 in surge protector; the waveform of lightning current and amplitude are analyzed; and excessively 485 ports 7 and communication line analysis result can be sent to host computer; after energy, bench control system records the time that thunderbolt occurs in detail; wave character, current parameters etc.
This surge protector adopts bus communication mode; background monitoring system reads the data of each surge protector according to different address codes; the running status of all surge protectors being arranged on different places can be monitored in real time; reduce attendant to the workload of site inspection, can examine and replace in time when the surge protector in somewhere breaks down.
This surge protector is built with thermal release device; when the component aging in surge protector lost efficacy; the electric current that components and parts flow through can increase; components and parts generate heat; the thermal release device action when reaching certain temperature; automatically surge protector and supply line can be separated, preventing short circuit accident.
Also thunder-and-lightning counter is housed in this surge protector, can do rough estimates to the number of lightning strokes of protected supply line, counter has intelligent sleep mode, adopts the method for time delay display, seldom bright, can save power consumption.
This surge protector, built with sound and light alarm device, when surge protector lost efficacy, can remind attendant to carry out examine and replace.
The utility model can allow the surge protector in the same area form network; by 485 bus communication modes, in the operating state of each surge protector of backstage Real-Time Monitoring, the surge protector lost efficacy is changed in time; prevent the generation of lightning strike accident, alleviate the working strength of attendant.
As installed and used this surge protector widely in locality; local number of lightning strokes in detail can be collected, annual thunderbolt distribution situation, the current parameters of each thunderbolt; scientific basis is provided, for the lightning protection mitigation work of locality provides scientific basis to the thunderbolt situation analysis of locality.
Use this type surge protector than common surge protector electrical energy saving.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that technical solutions of the utility model are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all in protection range of the present utility model without to improve.
