Abstract
The invention belongs to the technical field of electric power, and particularly relates to an antenna feeder protector with an automatic alarm function. The antenna feeder protector comprises a shell and a varistor arranged in the shell. An independent detection circuit is connected to the varistor and an alarm respectively. The antenna feeder has the advantages that the problem that the prior protectors all have no automatic alarm function, and operating condition of the protectors cannot be always known, thus measures can't be taken timely is solved; visualization is achieved, and use is convenient and quick.
Description
Technical field
The invention belongs to technical field of electric power, be specifically related to a kind of antenna feeder protector capable of automatic alarm.
Background technology
Antenna feeder protector is a kind of electronic product being applied in antenna lightning protection, is a kind of surge protector, and its principle mainly relies on inner piezo-resistance after the voltage at its two ends reaches certain numerical value, and Resistance versus voltage very responsive characteristic carrys out work.
Antenna feeder protector is very important for the lightning protection of equipment; therefore its normal work must be ensured; existing antenna feeder protector does not all have the function of automatic alarm; repair and maintenance personnel are generally needed often to go to detect with instrument; therefore; can not know the quality of protector at any time, if the protection period breaks down in the time period between twice detection, thunder and lightning weather just may cause immeasurable injury to protected equipment.
Summary of the invention
The object of the invention is to overcome antenna feeder protector in prior art and all there is no the function of automatic alarm, the quality of protector can not be known at any time and the problem of taking measures.
For this reason, the invention provides a kind of antenna feeder protector capable of automatic alarm, comprise the piezo-resistance of housing and enclosure interior, connect an independently testing circuit to piezo-resistance, testing circuit connects an alarm.
Described alarm is arranged on indoor.
Described testing circuit comprises impulse current generator, regulating resistance, voltmeter, switch and processor, the series connection of impulse current generator, regulating resistance, switch and piezo-resistance becomes loop, voltmeter is in parallel with piezo-resistance tests its both end voltage, voltmeter connection handling device, processor connects alarm.
This antenna feeder protector capable of automatic alarm provided by the invention, can the operating state of automatic detecting protector, gives the alarm and allows user know and take measures, be provided with the function of automatic alarm when its cisco unity malfunction.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Fig. 2 is testing circuit fundamental diagram
Description of reference numerals: 1, housing; 2, piezo-resistance; 3, testing circuit; 4, alarm; 5, impulse current generator; 6, regulating resistance; 7, voltmeter; 8, switch; 9, processor.
Embodiment
Embodiment 1:
An antenna feeder protector capable of automatic alarm, as shown in Figure 1, comprises the piezo-resistance 2 of housing 1 and housing 1 inside, it is characterized in that: connect an independently testing circuit 3 to piezo-resistance 2, testing circuit 3 connects an alarm 4.
After the piezo-resistance 2 of protection for feed line device on same day inside breaks down; testing circuit 3 can detect the fault of piezo-resistance 2 and pass to alarm 4 and respond; because alarm 4 is arranged on indoor easily by the place seen, at this time user will notice this situation, and takes necessary measure.
Embodiment 2:
Described testing circuit 3 comprises impulse current generator 5, regulating resistance 6, voltmeter 7, switch 8 and processor 9, the series connection of impulse current generator 5, regulating resistance 6, switch 8 and piezo-resistance 2 becomes loop, voltmeter 7 is in parallel with piezo-resistance 2 tests its both end voltage, voltmeter 7 connection handling device 9, processor 9 connects alarm 4.
As shown in Figure 2, impulse current generator 5 can provide the measurement electric current of the 1mA of an interval to circuit, switch 8 constantly converts contact position, and voltmeter 7 records the magnitude of voltage of positive and negative both direction, i.e. nominal conducting voltage.
Impulse current generator 5 has certain work period, 5S is one-period, the data recorded in one-period all pass to processor 9 by voltmeter 7, processor 9 pairs of data analysis judge, if voltage change ratio is greater than 10%, then show that piezo-resistance 2 breaks down, processor 9 can carry out alarm by triggered alarm 4.In sum; this antenna feeder protector capable of automatic alarm provided by the invention; constantly antenna feeder protector is detected by the effect of testing circuit; just give the alarm when it breaks down; solve antenna feeder protector in prior art and all there is no the function of automatic alarm, the quality of protector can not be known at any time and the problem of taking measures.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
