Abstract
The utility model discloses an anti-lighting household protector, comprising an anti-lighting protection unit, a control protection unit, a signal acquisition detection unit, and a bi-node current breaking unit. The anti-lighting protection unit comprises a third pressure-sensitive resistor connected across between a zero line and a live wire at a wire incoming end, and a first pressure-sensitive resistor and a second pressure-sensitive resistor, which are respectively connected with the zero line and the live wire at a wire outgoing end. The first pressure-sensitive resistor and the second pressure-sensitive resistor are grounded through a tripolar gas discharge tube. The technical scheme not only can prevent lightning stroke surges from damaging the protector, but also can prevent the lightning stroke surges from damaging products at the lower end of a line.
Description
Technical field
The utility model relates to a kind of lightning protection family expenses protector.
Background technology
Information-based family expenses protector is the Based Intelligent Control electrical equipment that uses during the power supply and distribution of electric power intellectualizing system is built; can be automatically and remote deciliter power supply-distribution system rated current; quick selectively disjunction phase relation electric current when the power supply-distribution system fault; and overstep tripping or misaction can not occur, can also read accident cause simultaneously.Realize the management of distribution network intellectuality, digitlization, networking, real time implementation, precision.
Information-based family expenses protector has used current node breaking technology, electronic technology, Electric automation technology, the network communications technology, computer and software engineering thereof etc.; adopt modular construction; broken through the tactic pattern of conventional domestic protector fully, integrated protection, measure, monitor.Except possessing conventional control, protection, warning, the setting functions such as overload, overcurrent, quick-break, electric leakage, ground connection, also possess simultaneously human-computer dialogue demonstration, storage, memory, logic analysis, judgement and the functions such as selection and network service.Can show in real time the various electricity consumption characteristic parameters of distribution network and carry out the storage of fault parameter, type, have self diagnostic capability, can retrieve rapidly corresponding fault message.Particularly New type of current node breaking technology has been used in information-based family expenses protection, makes small product size less, has broken through the volume restrictions of electronic breaker, uses more convenient.
In the prior art, the lightning protection unit provides effective lightning protection to user load circuit and protector itself.The characteristic of various lightning protection components is different, and such as the switch element class, but the very high reaction of puncture voltage is slower, and the pressure cell puncture voltage is relatively low but reaction speed is fast.
Summary of the invention
In order to solve above-mentioned technical problem; the purpose of this utility model provides a kind of lightning protection family expenses protector; various lightning protection devices are combined; consist of a lightning protection redundant circuit; not only combine the advantage of each lightning protection device but also abandoned their shortcoming, the interference to circuit so that whole circuit can effectively prevent from being struck by lightning.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of lightning protection family expenses protector; comprise lightning protection unit, control protected location, signal acquisition testing unit and binode electric current disjunction unit; described lightning protection unit comprises: be connected across the zero line of end of incoming cables and the 3rd piezo-resistance between the live wire; and the zero line and the first piezo-resistance on the live wire and the second piezo-resistance that are connected on respectively leading-out terminal, the first piezo-resistance and the second piezo-resistance are via three utmost point gas discharge tube ground connection.
The utility model combines various lightning protection devices owing to having adopted above technical scheme, consists of a lightning protection redundant circuit, not only combines the advantage of each lightning protection device but also abandoned their shortcoming, the interference to circuit so that whole circuit can effectively prevent from being struck by lightning.Both can prevent lightning surge to the infringement of this product, and can also protect to prevent that lightning surge is to the product infringement of circuit lower end.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of lightning protection family expenses protector as shown in Figure 1; comprise lightning protection unit 400, control protected location 200, signal acquisition testing unit 100 and binode electric current disjunction unit 300; this lightning protection unit 400 comprises: be connected across the zero line of end of incoming cables and the 3rd piezo-resistance RV3 between the live wire; and the zero line and the first piezo-resistance on the live wire and the second piezo-resistance that are connected on respectively leading-out terminal, the first piezo-resistance RV1 and the second piezo-resistance RV2 are via three utmost point gas discharge tube ground connection.Piezo-resistance RV1, RV2 and three utmost point gas discharge tubes form the leading-out terminal lightning protection circuit.Because piezo-resistance has larger parasitic capacitance, is used in AC power supply system, can produce considerable leakage current, after the piezo-resistance of poor-performing is used a period of time, because leakage current becomes the self-destruction of may generating heat greatly.Between piezo-resistance, seal in gas discharge tube for addressing this problem.With after gas discharge tube is connected, because the gas discharge tube parasitic capacitance is very little, can make the total capacitance of series arm reduce to several pF piezo-resistance.In this branch road, gas discharge tube will play an on-off action, and when not having transient voltage, it can separate piezo-resistance and system, makes piezo-resistance almost without leakage current.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
