Abstract
The utility model relates to radio transmission apparatus technical field, especially a kind of Fault detection filter.Media qualities in existing dielectric filter differs, and often occurs the situation that medium is bad, and the words that evening finds are easy to affect filtration efficiency, adds filter and is subject to when connecting up the interference ratio of signal ground larger.This Fault detection filter comprises the medium of filter main body and filter main body inside, is provided with liquid taking port outside medium, is provided with metallic plate bottom filter main body, is provided with telescopic outrigger below metallic plate.Fault detection filter structure after improvement is simple, and working stability is reliable, detects in time and finds media problem, effectively alleviating the interference of signal ground to filtering, for filter wire laying provides neatly, effectively improve filtration efficiency.
Description
Technical field
The utility model relates to radio transmission apparatus technical field, especially a kind of Fault detection filter.
Background technology
The filter circuit that power-supply filter is made up of electric capacity, inductance and resistance, a kind of passive bidirectional network, its one end is power supply, the other end is load, it is the device that ripple is filtered, it can carry out effective filtering to the frequency beyond the frequency of characteristic frequency in power line or this frequency, obtains the power supply signal of a characteristic frequency, or eliminates the power supply signal after a characteristic frequency.Media qualities in existing dielectric filter differs, and often occurs the situation that medium is bad, and the words that evening finds are easy to affect filtration efficiency, adds filter and is subject to when connecting up the interference ratio of signal ground larger.
Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of Fault detection filter.
The utility model solves the technical scheme that its technical problem adopts: a kind of Fault detection filter, comprise the medium of filter main body and filter main body inside, be provided with liquid taking port outside medium, bottom filter main body, be provided with metallic plate, below metallic plate, be provided with telescopic outrigger.
The beneficial effects of the utility model are, structure is simple, and working stability is reliable, detect in time and find media problem, effectively alleviating the interference of signal ground to filtering, for filter wire laying provides neatly, effectively improve filtration efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. filter main body, 2. medium, 3. liquid taking port, 4. metallic plate, 5. telescopic outrigger in figure.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of Fault detection filter, comprises the medium 2 of filter main body 1 and filter main body 1 inside, is provided with liquid taking port 3 outside medium 2, be provided with metallic plate 4 bottom filter main body 1, be provided with telescopic outrigger 5 below metallic plate 4.
In the course of work, if filtration efficiency declines to some extent, but can not determine when being what problem on earth, whether a medium 2 can be got from liquid taking port 3 to verify that medium 2 is bad on earth and cause, eliminate the trouble of dismounting filter, when determining to use on-board filter, interference during wiring on known signal ground is very serious, is blocked can be isolated near-field interference by metallic plate 4.
Fault detection filter structure after improvement is simple, and working stability is reliable, detects in time and finds media problem, effectively alleviating the interference of signal ground to filtering, for filter wire laying provides neatly, effectively improve filtration efficiency.
