Abstract
The utility model relates to a protection device of a circuit system, in particular to a surge protector. The surge protector comprises a lightning protection module, a lightning protection base to which the lightning protection module is fixed, a leakage current detection unit, a singlechip and an alarm, wherein the leakage current detection unit and the alarm are connected with the singlechip respectively. According to the structure, leakage current is detected through the leakage current detection unit, and a signal is transmitted to the alarm through the singlechip for giving an alarm, so that maintenance personnel can be prompted to replace the surge protector; and the singlechip adopts a communication chip 485 which is very strong in common-mode interference resistance and can achieve a remote monitoring function at the same time, so that even if the maintenance personnel is not on the scene, the leakage current can be also monitored in time.
Description
Technical field
The utility model relates to a kind of protective device of Circuits System, especially a kind of surge protector.
Background technology
Surge protector (S urge prote ctio n D evi c e) is indispensable a kind of device in the electronic equipment lightning protection, and the past often is called, surge protector.The effect that " lightning arrester " or " overvoltage protection device " English is abbreviated as S P D. surge protector is that the instantaneous overvoltage of scurrying into power line, signal transmssion line is limited in the voltage range that equipment or system can bear; or powerful lightning current let out the inflow place, protect protected equipment or system not to be hit and damage.The type of surge protector is different by different purposes with structure, but it should comprise a non-linear voltage limiting element at least.The basic components and parts that are used for surge protector have: discharging gap, gas-discharge tube, piezo-resistance, inhibition diode and choking-winding etc.
But at present the self-protection ability of surge protector is more weak, because surge protector when using relatively for a long time, is easy to the situation that occurs leaking electricity, causes fire easily, therefore exists potential safety hazard.
Summary of the invention
The purpose of this utility model is, a kind of surge protector of monitoring leakage current, can report to the police automatically is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of surge protector; comprise lightning-protection module, lightning protection base; lightning-protection module is fixed on the lightning protection base; also comprise leakage current detecting unit, single-chip microcomputer, alarm, leakage current detecting unit, alarm are connected with single-chip microcomputer respectively.
Of the present utility modelly further be set to: described alarm is an indicator light, and indicator light is fixed on the top of lightning protection base.
Of the present utility modelly further be set to: described leakage current detecting unit is a leakage current sensor, and leakage current sensor is installed on the positive and negative leading-out terminal of lightning protection base.
Of the present utility modelly further be set to: described single-chip microcomputer is 485 communication chips.
Said structure utilizes the leakage current detecting unit to detect leakage current and transfers signals on the alarm by single-chip microcomputer then and report to the police; can point out the maintainer to change surge protector; and monolithic adopts 485 communication chips; 485 communication chips have very strong anti-common mode disturbances ability; simultaneously can realize long-range monitoring function; even the maintainer not at the scene, also can in time monitor.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is the principle sketch of present embodiment.
Embodiment
With reference to figure 1; Fig. 2 as can be known; a kind of surge protector; comprise lightning-protection module 1; lightning protection base 2; lightning-protection module 1 is fixed on the lightning protection base 2; also comprise the leakage current detecting unit; single-chip microcomputer; alarm; the leakage current detecting unit; alarm is connected with single-chip microcomputer respectively; described alarm is an indicator light 3; indicator light 3 is fixed on the top of lightning protection base 2; described leakage current detecting unit is a leakage current sensor; leakage current sensor is installed on the positive and negative leading-out terminal of lightning protection base (one of ordinary skilled in the art all know wherein do not do sign among the figure); described single-chip microcomputer is 485 communication chips, makes things convenient for the utility model to realize the function of telecommunication and remote monitoring.
Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being extended out thus or change still are in the protection range of the present utility model.
