The cost control and anti-stealing electric metering cabinet has been continuously upgraded, and its safety performance and technical performance have been greatly improved compared with the parent series, which has brought a qualitative leap to the safety, accuracy and reliability of electric metering.


1. Improvement of the input-outlet scheme: the installation holes of upper and lower input-outlet lines are designed and reserved in the same cabinet, which can be conveniently and flexibly combined with other input-outlet schemes, greatly improving the general performance of the metering cabinet in the combination;


2. Primary and secondary isolation:


(1) when the metering system needs to be repaired, the conventional method is to cut off the power of the user before the work, which not only reduces the power supply, but also affects the normal power consumption of the user;


(2) the burglar type measuring ark, will be the primary and secondary wiring and measuring element set respectively in different area, and the device isolation plate, make the primary and secondary lines and PT and CT wiring in completely isolated indoor, this can prevent a failure of the secondary measuring element damage, also can conveniently, and securely power measurement of maintenance and replacement of PT insurance work.


3, for the power loss of retroactive measures: in normal measuring run, if the PT and CT appeared lack of phase or block, can cause for the power loss, so the burglar metering cabinet installed DJL - V cutoff pressure loss chronograph, can the chronograph in PT and CT phase to flow accurately make timing, to power a retroactive provides strong scientific basis;


4. Password control part: this part takes the advanced special digital processing chip in the world as the core, and forms the password compiling, saving and solving system. It is equipped with preset switch.



The charging power is taken from the secondary voltage of PT, and the battery voltage is allowed to drop to 90% of the standard value.
