Abstract
The invention provides a method for protecting an electric energy meter calibrating device block watch seat (also known as rapid junction box or a block access seat), comprising the following steps: the temperature of a block watch seat is monitored; if the temperature of the block watch seat reaches a preset temperature limit point, an alarming signal is output; and a power source is closed so as to protect the block watch seat with abnormal temperature. The method for protecting the electric energy meter calibrating device block watch seat can realize the monitoring to the abnormal conditions of the block watch seat by monitoring the temperature thereof; when the temperature of the block watch seat reaches a preset temperature limit point, a form of giving alarm and automatically closing the power source is used for protecting the block watch seat with abnormal conditions; simultaneously, the block watch seat with abnormal conditions can be pointed out automatically and thus timely discovery of failures and smooth exclusion thereof can be ensured.
Description
Technical field
The present invention relates to a kind of guard method, particularly about a kind of guard method that is used for hanging base of electric energy meter calibrating apparatus.
Background technology
The pocket watch seat (quick connector or meter adapting-seat) of being furnished with electric energy meter in the electric energy meter calibrating apparatus, its effect are quick stationary electric tables and provide current signal (model that has provides voltage signal) to electric energy meter.
The current signal scope of electric energy meter is very wide from 0.001A～120A, in use owing to have contact resistance between the pocket watch seat (quick connector or meter adapting-seat) of electric energy meter and the electric energy meter, when big current work, can influence the work of electric energy meter calibrating apparatus because the too high pocket watch seat (quick connector or meter adapting-seat) that causes of temperature rise burn out.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of method for protecting hanging base of electric energy meter calibrating apparatus that can effectively realize temperature monitoring.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method for protecting hanging base of electric energy meter calibrating apparatus is provided, and it may further comprise the steps: the temperature to the pocket watch seat is monitored; If the temperature of pocket watch seat arrives default temperature extremes point, output alarm signal; Closing power source protects the pocket watch seat of temperature anomaly.
The scheme that the present invention solves further technical matters is: contact temperature-measuring is adopted in above-mentioned monitoring to temperature.
The scheme that the present invention solves further technical matters is: described contact temperature-measuring is to measure temperature by thermistor or thermocouple.
The scheme that the present invention solves further technical matters is: contactless temperature-measuring is adopted in above-mentioned monitoring to temperature.
Compared to prior art; method for protecting hanging base of electric energy meter calibrating apparatus of the present invention is by realizing the temperature monitoring of pocket watch seat its unusual monitoring; when the temperature of this pocket watch seat reaches default temperature extremes point; adopt the mode of also closing power source automatically of reporting to the police to come unusual pocket watch seat is protected; simultaneously can indicate unusual pocket watch seat automatically; can guarantee timely discovery, get rid of smoothly fault.
Description of drawings
Fig. 1 is the schematic flow sheet of method for protecting hanging base of electric energy meter calibrating apparatus of the present invention.
Fig. 2 is the principle of work synoptic diagram of method for protecting hanging base of electric energy meter calibrating apparatus of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of method for protecting hanging base of electric energy meter calibrating apparatus, it may further comprise the steps: the temperature to the pocket watch seat is monitored; If the temperature of pocket watch seat arrives default temperature extremes point, output alarm signal; Closing power source protects the pocket watch seat of temperature anomaly.
Above-mentioned monitoring to temperature can realize in the following manner: thermistor, contact temperature-measuring or other contactless temperature-measurings such as thermocouple.
Method for protecting hanging base of electric energy meter calibrating apparatus of the present invention is the unusual pocket watch seat of indicated temperature automatically.
As shown in Figure 2, control module detects the temperature fault of joining with hanging base of electric energy meter calibrating apparatus in real time and detects indicating circuit, and the temperature fault testing circuit is measured the temperature of hanging base of electric energy meter calibrating apparatus by temperature measurement unit.The state that control module detects fault detect indicating circuit indication is temperature when too high, and the power controlling source is closed power output and protected immediately.
Method for protecting hanging base of electric energy meter calibrating apparatus of the present invention is by realizing the temperature monitoring of pocket watch seat its unusual monitoring; when the temperature of this pocket watch seat reaches default temperature extremes point; adopt the mode of also closing power source automatically of reporting to the police to come unusual pocket watch seat is protected; simultaneously can indicate unusual pocket watch seat automatically; can guarantee timely discovery, get rid of smoothly fault.
