Block connects, for recording the data of metering module metering；Microcontroller, is connected with described metering module, from described metering module
Read continuous data and carry out following process: calculate active power, reactive power respectively, regard according to the data of metering module metering
In power, voltage effective value and current effective value data；Load data is calculated according to active power；Load data is remembered
Record, display and Communication processing；Self-inspection is processed, and self-inspection timesharing setting mistake, nonvolatile storage mistake, clock error, metering are wrong
By mistake, battery undervoltage mistake；Power supply, is connected with described metering module and microcontroller respectively, provides described electric energy meter working power；
Described electric power signal sampling module, metering module, logging modle, microcontroller and power supply are all disposed within housing；
The accommodating chamber t2 accommodating into mechanism of qi t3 is set up inside described cabinet t1；Air inlet is set up in described accommodating chamber t3
The lower end of machine t3, described accommodating chamber t2 has through injection well t4, and described injection well t4 is connected with air guide channel t5, in addition
Second sieve tray t7 is arranged on the backing of described injection well t4, in addition the afterbody of described air guide channel t5 is aspirating end t6,
Described aspirating end t6 is arranged in cabinet t1 rear wall, and in addition described aspirating end t6 communicates with inside cabinet t1；Described aspirating end
T6 is towards the part t8 setting of electric power signal sampling module, metering module, logging modle, microcontroller and power supply, during operation, warp
Led towards in cabinet t1 into outer gas stream by entering mechanism of qi t3, realize the refrigeration for cabinet t1, high cooling efficiency, improve electric energy letter
Number sampling module, metering module, the working environment of the part t8 of logging modle, microcontroller and power supply, fault rate is also dropped
Low, the impurity that in addition the second sieve tray t7 also reduces in outer gas stream enters the invasion of cabinet, and described aspirating end t6 is towards electricity
Energy signal sampling module, metering module, the part t8 setting of logging modle, microcontroller and power supply make to ensure that refrigeration has pin
To property, further improving refrigerating efficiency, reducing power consumption it is therefore prevented that losing.
Such cabinet is led into outer gas stream via entering mechanism of qi t3 towards in cabinet t1, realizes the refrigeration for cabinet t1, system
Cold efficiency is high, improves the work of the part t8 of electric power signal sampling module, metering module, logging modle, microcontroller and power supply
Make environment, fault rate is also minimized, the impurity that in addition the second sieve tray t7 also reduces in outer gas stream enters invading of cabinet
Disturb, described aspirating end t6 is towards the part t8 of electric power signal sampling module, metering module, logging modle, microcontroller and power supply
Arranging and make to ensure that refrigeration targetedly, further improves refrigerating efficiency, reducing power consumption it is therefore prevented that losing.
The material of described air guide channel t5 is rubber so that flexible.
In addition existing housing is coated with pressure-sensitive adhesive coating, described pressure-sensitive adhesive coating and cabinet often by its surface
Inwall bonding, to be thus fixed effect, and gel coating often viscous effect, such structure tends to be occurred loosening
Problem, thus lead to housing to be not easy connection firmly loosening.
In addition the outer wall of described housing passes through the inwall connection with cabinet for the connector；
The concrete structure of described connector is: its contain the first scarfing unit unit a06 on the inwall being fixed on cabinet with
Be fixed on the second scarfing unit unit a01 on the outer wall of housing, described first scarfing unit unit a06 have interlocking mouth a07 and
