Abstract
The utility model belongs to the technical field of electric power, and specifically relates to an antenna feeder protection device capable of automatic alarming. The antenna feeder protection device comprises a housing and a varistor in the housing. An independent detection circuit is connected with the varistor. The detection circuit is connected with an alarm. The antenna feeder protection device capable of automatic alarming solves problems that antenna feeder protection devices in the prior art do not have an automatic alarming function, the condition of the protection devices cannot be mastered at anytime and thus measures cannot be taken, and is has the characteristics of being visual, convenient and simple.
Description
Technical field
The utility model belongs to power technology field, is specifically related to a kind of antenna feeder protector capable of automatic alarm.
Background technology
Antenna feeder protector is a kind of electronic product that is applied in antenna lightning protection, be a kind of surge protector, and its principle is mainly to rely on inner piezo-resistance to reach after certain numerical value at the voltage at its two ends, and resistance carrys out work to the very responsive characteristic of voltage.
Antenna feeder protector is very important for the lightning protection of equipment; therefore must ensure its normal work; existing antenna feeder protector does not all have the function of automatic alarm; generally need repair and maintenance personnel often to go to detect with instrument; therefore; can not know at any time the quality of protector, 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 purpose of this utility model is to overcome antenna feeder protector in prior art all there is no the function of automatic alarm, can not know at any time the quality of protector the problem of taking measures.
For this reason, the utility model provides a kind of antenna feeder protector capable of automatic alarm, comprises the piezo-resistance of housing and enclosure interior, connects an independently testing circuit to piezo-resistance, and testing circuit connects an alarm.
Described alarm is arranged on indoor.
Described testing circuit comprises impulse current generator, regulating resistance, voltmeter, switch and processor, impulse current generator, regulating resistance, switch and piezo-resistance series connection become loop, voltmeter test its both end voltage in parallel with piezo-resistance, voltmeter connects processor, and processor connects alarm.
The antenna feeder protector this capable of automatic alarm that the utility model provides, operating state that can automatic detecting protector gives the alarm and allows user know and take measures in the time of its cisco unity malfunction, has had the function of automatic alarm.
Below with reference to accompanying drawing, the utility model is described in further details.

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 the indoor place of easily being 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, impulse current generator 5, regulating resistance 6, switch 8 and piezo-resistance 2 series connection become loop, voltmeter 7 test its both end voltage in parallel with piezo-resistance 2, voltmeter 7 connects processor 9, and processor 9 connects alarm 4.
As shown in Figure 2, impulse current generator 5 can provide the measurement electric current of the 1mA at an intermittence to circuit, and switch 8 is conversion contact position constantly, 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 that record in one-period are all passed to processor 9 by voltmeter 7, processor 9 judges data analysis, if voltage change ratio is greater than 10%, show that piezo-resistance 2 breaks down, processor 9 can carry out alarm by trigger alarm device 4.In sum; the antenna feeder protector this capable of automatic alarm that the utility model provides; effect by testing circuit constantly detects antenna feeder protector; when breaking down, it just gives the alarm; having solved antenna feeder protector in prior art does not all have the function of automatic alarm, can not know at any time the quality of protector the problem of taking measures.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection range of the present utility model, within the every and same or analogous design of the utility model all belongs to protection scope of the present invention.
