Our advantages
The meter can be used in the Prepaid Power Vending Management
System.repaid power vending management system is based on power
vending management software and database with the devices of
computer, charging machine, prepaid meters, printers and security
modules, etc.It has the following advantages:
1. Archives management: information creating and import for
departments, users .
2. Parameters setting: electricity price, meter configuration, etc.
3. Business management: creating accounts for new meters, meter
changes, meter ownership transfer, customer information
cancellation, power vending, disconnection and reconnection.
4. Data inquiry: power vending inquiry according to date, month,
year, customers, distribution transformers, departments.
5. Data analysis: power vending analysis,drawing, report printing
according to time, customers, distribution transformers, etc.
6. Rights management: operator management, operator password
modification, etc.
System Architectur
Q & A
Q: What kind of requirements do smart energy meter have to load switch?
A: ① The load switch of smart energy meter can be divided into
internal or external mode.
② When it adopts the internal load switch, the maximum current of
energy meter should not be more than 60A.
switch operation shall have Acr suppression measures (hardware or
software), and its export loop shall have safety measures for anti
false action and being easy to field test. Under the condition of
above current, the lifetime of switch shall not be less than 6000
times. Imposing reference voltage on voltage circuit of energy
meter, and under the condition of passing 1.2Imax to current
circuit, carries out switch on and off test for 10 times; After the
test, the energy meter shall work normally; when imposing 70% to
120% reference voltage on voltage circuit of energy meter, the load
switch shall work normally.
③ When it adopts external load switch, energy meter shall output a
set of switch signals, and the capacity of switch node is AC 250V,
2A. During normal operation, the outgoing switch signals shall
maintain load switch closing and allow users to use electricity.
When the control conditions are satisfied, the outgoing switch
signals shall drive external load switch action and interrupt power
supply.
