Clock system standard source and work method

Abstract

The invention relates to a clock system standard source and a work method. In the traditional general checkout platform of multi-function watt-hour meters, generally, every device is provided with an independent clock apparatus, the number of the clock apparatuses is large, the cost of the clock apparatuses is high, and the clock apparatuses need submittal for inspection every year, which wastes time and labor. The invention is characterized by comprising a clock apparatus, a driving plate and a plurality of isolation switch plates, wherein the driving plate which is connected with the clock apparatus is used for frequency division and shaping for high frequency pulses; the isolation switch plates which are connected with the driving plate are used for electrical isolation, the output of the isolation switch plates is connected with an error inspection device so that frequency division clock signals are isolated and sent to the error inspection device. The invention has the advantages of convenience of submittal for inspection, low cost, high inspection accuracy and high stability.

Description

technical field [0001] The invention relates to a clock system standard source and a working method. Background technique [0002] In the existing multi-function electric energy meter ordinary calibration station, each device is generally equipped with an independent clock instrument for verifying the clock accuracy inside the electric energy meter, and the meter calibration device on each floor of the verification assembly line is generally within a few Tens or even hundreds of sets, the corresponding clocks also need dozens or even hundreds of sets. The quantity is large and the cost is high. Moreover, the clocks have to be inspected every year, which is time-consuming and laborious. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, provide a clock system standard source and working method, so as to achieve the goals of low cost, high ...
