Description
Technical field
The utility model relates to a kind of device that kills mouse through electromagnetic field, relates in particular to a kind of electromagnetic deratization device that is used in the high voltage power distributing cabinet.
Background technology
In the accident of present power system, 10% the accident of having an appointment is because the short circuit of high voltage power distributing cabinet median generatrix causes, and this wherein, except equipment fault, because mouse trouble causes the high voltage power distributing cabinet busbar short-circuit to account for maximum ratio.Present various large and small type switchgear house; All be provided with facilities such as ratguard, rodent-proof mesh, sticking mouse subsides mostly and prevent and treat mouse trouble, still such method is all cured the symptoms, not the disease, and can not fundamentally break off the problem that distribution facility is suffered from by mouse; Because the scale of power system now is increasing; Therefore suffer from as if this mouse of leaving and taking place, and can not fundamentally suppress this problem, will cause enormous economic loss.
Summary of the invention
The technical problem that the utility model will solve: a kind of high voltage power distributing cabinet electromagnetic deratization device is provided, adopts facilities such as ratguard, rodent-proof mesh to prevent that mouse from suffering from, still can not prevent problems such as mouse trouble fully to solve the high voltage power distributing cabinet distribution facility.
The utility model technical scheme:
A kind of high voltage power distributing cabinet electromagnetic deratization device, it comprises: power module, controller, raddiating circuit and radiant panel, power module is connected with the controller lead; Controller is connected with the isolated drive circuit lead; Isolated drive circuit is connected with the inverter circuit lead, and inverter circuit is connected with the raddiating circuit lead, and raddiating circuit is connected with the radiant panel lead; Controller is connected with the decoder lead; Decoder is connected with the buffering driving lead, and buffering drives and is connected with the vector control module lead, and vector control module is connected with the raddiating circuit lead.
Raddiating circuit is connected with the overcurrent detecting device lead, and overcurrent detecting device is connected with the controller lead.
The electromagnetic deratization device is installed in the bus bar configuration zone of high voltage power distributing cabinet.
The beneficial effect of the utility model:
The utility model is installed in the high voltage power distributing cabinet; The combination frequency of the wide spectrum at random signal that AT89S51 produces produces rectangular pulse, amplifies through driver for isolating; The control of delivering to inversion electric furnace two brachium pontis through current-limiting resistance is again extremely gone up, and just can produce the ac square wave signal.According to its encoding characteristics, the group relay in the decision radiation furnace is closed, thereby realizes the variation of electromagnetic field direction.The laying apparatu of native system mainly is used for taking place the pulse electromagnetic field of 1Hz～1024Hz scope, through the utility model, 8 magnetic direction rotating excitation fields can be provided, and possesses the randomness of multifrequency signal.Its 2n fundamental frequency, dutycycle can arbitrarily be provided with, in use change voluntarily.The very low frequencies that this device the produces system stable operation that kills mouse, the direction frequency accidental changes, and can be used for high voltage power distributing cabinet fully and evade the plague of rats.
Description of drawings:
Fig. 1 is the utility model embodiment sketch map.
Embodiment:
A kind of high voltage power distributing cabinet electromagnetic deratization device (see figure 1), it comprises: power module, controller, raddiating circuit and radiant panel, power module adopt input AC 220V to change the dc source of direct current 5V; The 5V dc source of output is through lead access controller power input; Controller adopts AT89S51 single-chip microcomputer or other model single-chip microcomputers to form, and the output of controller inserts isolated drive circuit through lead, sends into inverter circuit from the signal conductor that isolated drive circuit comes out; Inverter circuit is connected with the raddiating circuit lead; Raddiating circuit is connected with the radiant panel lead, and controller is connected with the decoder lead, and decoder is connected with the buffering driving lead; Buffering drives and is connected with the vector control module lead, and vector control module is connected with the raddiating circuit lead.
Raddiating circuit is connected with the overcurrent detecting device lead; Overcurrent detecting device is connected with the controller lead; Overcurrent detecting device adopts the AD analog-digital commutator, the analog quantity current signal of raddiating circuit is become data signal through the AD analog-digital commutator send into controller, in case electric current is greater than predetermined current; Controller is regulated output area automatically, makes output valve in allowed band.
Controller output adaptive code signal is to decoding circuit; After buffering drives amplification, deliver to vector control module again, realize control, thereby realize the change at random of electromagnetic field raddiating circuit; Decoder adopts the 74LS138 decoder, and buffering drives and adopts 7407 modules.
The electromagnetic deratization device is installed in the bus bar configuration zone in the high voltage power distributing cabinet, realizes the focused protection to bus.
