Shown in Fig. 1 to Fig. 2, it is related to a kind of high voltage electric net device, including the interior power network main frame provided with emergency button, the electricity The output end of host's machine is connected by 485 buses with multiple power network extension sets；When the power network main frame because failure can not normal work When making, emergency service can be carried out to the power network extension set by the emergency button；It is uninterrupted to ensure that high pressure intercepts function；Extension set Can independent operating work, can be also managed collectively by main frame.It can make electric net device not because a certain part occurs in this way Failure and the normal operation for influenceing whole system.

Fig. 2 is the functional schematic of power network main frame, and the power network main frame includes CPU processing units 21, and its first communication connects Mouth end is connected with keyboard 22, and its second communication interface end is connected with LCD MODULE 23, and its 3rd communication interface end refers to LED Show that lamp 24 connects, its 4th communication interface end is connected with switching value output module 25, its 5th communication interface end and extension set 485 Communication module 26 is connected, and its 6th communication interface end is connected with alarm output module 27, its 7th communication interface end and TCP/IP Network communication module 28 is connected, and its 8th communication interface end is connected with 485 dataphone modules 29；

Wherein, running parameter is inputted central processing unit by keyboard and broadcasts to each power network point by central processing unit Machine；LCD MODULE can inquire about various arranges values, and by works such as each power network extension set present operating voltage, electric current, strike electric currents Make state real-time display to come out；LED light can intuitively find out each extension set whether normal work and net-fault, suspension, short circuit, withdraw a garrison Etc. alarm condition；Alarm output module can provide the alarm switch amount signal output of each power network extension set, convenient to be set with other Standby linkage；485 extension set communication modules are responsible for communicating between main frame and extension set；It is defeated that alarm output module provides total alarm switch amount Go out, acoustic-optic alarm can be driven, can know that TCP/IP network communication modules are to pass through in time to there is policeman after alert Main frame access to LAN is realized remote management by TCP/IP modes；485 dataphone modules are to be connect main frame using 485 modes Enter LAN, realize remote management.

The structure combines the management control function for realizing power network main frame by each feature board, gives maintenance, repair band To greatly facilitate；Electric net device will not should be some component malfunction and cause the paralysis of whole host computer system so that be The more stable operation of system；Maintenance cost is reduced, which part goes wrong changes for which part, has accomplished convenience, simple, reality With.User can set different fine day rainy day running parameter according to the weather conditions of locality simultaneously so that electric net device can be Any area uses.

The power network extension set includes the filter circuit that input exchanges electrical connection with 220V, and the first of the filter circuit is defeated Go out end to be connected with driving plate, the second output end of the filter circuit is connected with control panel；Wherein, the output end of the driving plate It is connected with step-up transformer, the first output end of the step-up transformer is connected to the first High voltage output by high voltage switching device End, the second output end of the step-up transformer are connected to the second High voltage output portion；The control signal of the control panel is led to 485 bus to be crossed to be connected with power network main frame, the detection signal detection input of the control panel is connected with detection conversion module, The voltage signal test side of the detection conversion module and the electric quantity signal test side output end with the step-up transformer respectively Connection.

In the system, the generation of high-tension electricity, which employs to tap into 220V alternating current directs after row zero passage detection, is added to extraordinary boosting The input of transformer, required high tension voltage is obtained after directly being boosted by special transformer.Use this scheme Major advantage is：1) electromagnetic interference is very small, does not disturb the normal work of other equipment；2) control accuracy is high, response speed It hurry up, it is possible to achieve timely precision strike；3) double winding output HIGH voltage, voltage between lines reach twice that single channel realizes voltage, The big raising of voltage breakdown ability, improve the effect of protection and tamper-proof ability.4) by Phototube Coupling, control is substantially increased The antijamming capability of system processed, it ensure that user uses the safety of equipment；5) controlled by control system, it is normal in assurance function On the premise of, the power consumption of system is very small, can greatly save using electric energy.
