Abstract
The utility model discloses a kind of power distribution cabinet with ageing of insulation status monitoring function, comprise power distribution cabinet body, on the intrinsic insulated conductor of power distribution cabinet, be connected with the little hook of metal, the little hook of metal is connected with current transformer by wire, current transformer also by wire successively with rectifier bridge, filter is connected, filter again by wire respectively with buzzer, light-emitting diode is connected, a kind of power distribution cabinet with ageing of insulation status monitoring function, solve the problem that in the power distribution cabinet existing in prior art, circuit ageing of insulation can not detect in time.
Description
Technical field
The utility model belongs to Electrical Control Technology field, is specifically related to a kind of power distribution cabinet with ageing of insulation status monitoring function.
Background technology
Since man invented and since making electricity consumption, electricity can not only bring a lot of convenience to the mankind, also can bring extinction to the mankind.It may burn out electrical equipment; cause fire; or people is got an electric shock; human body is damaged; serious even threat to life; and in electrical control industry; when operating personnel are most, be all to come into contacts with electricity; especially in high voltage power distributing cabinet, a lot of wires, because service time is longer, are easy to occur the problems such as line insulation is aging; once circuit is aging; corresponding insulation property have just lost due effect, and then can breaking out of fire and the accident of crisis personal safety, so that the insulation ageing problem of product seems is particularly important.
Utility model content
The object of the utility model product is to provide a kind of power distribution cabinet with ageing of insulation status monitoring function, has solved the problem that in the power distribution cabinet existing in prior art, circuit ageing of insulation can not detect in time.
The technical scheme that the utility model adopts is, a kind of power distribution cabinet with ageing of insulation status monitoring function, comprise power distribution cabinet body, on the intrinsic insulated conductor of power distribution cabinet, be connected with the little hook of metal, the little hook of metal is connected with current transformer by wire, current transformer is also connected with rectifier bridge, filter successively by wire, and filter is connected with buzzer, light-emitting diode respectively by wire again.
Feature of the present utility model is also,
Rectifier bridge is full bridge rectifier.
A kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model, beneficial effect is, can As time goes on there is aging phenomenon in apparatus insulated part, for preventing the generation of this phenomenon, at the insulated part of equipment, a kind of detecting devices is installed, in the time that equipment leakage electric current passes insulating barrier, the current signal sending is passed to device explanation by inductor has leakage current to occur to need to check and replacing insulating barrier.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model;
Fig. 2 is the circuit connection diagram of a kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model.
In figure, 1. power distribution cabinet body, 2. insulated conductor, 3. current transformer, 4. rectifier bridge, 5. filter, 6. buzzer, 7. light-emitting diode, the 8. little hook of metal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
A kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model, as shown in Figure 1, comprise power distribution cabinet body 1, on insulated conductor 2 in power distribution cabinet body 1, be connected with the little hook 8 of metal, the little hook 8 of metal is connected with current transformer 3 by wire, current transformer 3 is also connected with rectifier bridge 4, filter 5 successively by wire, and filter 5 is connected with buzzer 6, light-emitting diode 7 respectively by wire again, and rectifier bridge 4 is full bridge rectifier.
A kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model, the course of work is, little metal hook 8 is suspended on some older insulated conductors 2, in the time that power distribution cabinet body 1 switches on power, insulated conductor 2 inner cores have electric current and flow through, in the time there is aging phenomenon in the insulating barrier of insulated conductor 2, now on the little hook 8 of metal, have faint electric current and import current transformer 3 into by wire, AC current after current transformer 3 enters filter 5 again after rectifier bridge 4, by filter 5 by other signal filterings, current signal finally enters in buzzer 6 and light-emitting diode 7, now, buzzer 6 is reported to the police, simultaneously, light-emitting diode 7 is lighted, concrete circuit diagram as shown in Figure 2, just can conclude thus, there is aging phenomenon in the insulating barrier of insulated conductor 2, on the insulating barrier of insulated conductor 2, there is faint electric current, buzzer 6 sound are exactly to remind operating personnel to lose no time to change insulated conductor 2, avoid delay and cause personal injury.
A kind of power distribution cabinet with ageing of insulation status monitoring function of the utility model, at the insulated part installation detecting device of equipment, in the time that equipment leakage electric current passes insulating barrier, the current signal sending is passed to and is reported to the police and light-emitting device by a series of components and parts, insulating barrier electric leakage is described, needs to check and change insulating barrier.
Claims (2)
