Abstract
The utility model relates to a high-voltage user local charge-control intelligent ammeter. The intelligent ammeter comprises a power source device, a metering screen, a protecting screen and a circuit breaker device, wherein the power source device is connected with the metering screen and the protecting screen in series through the circuit breaker device, and when the remaining amount of the ammeter is lower than an overdraft threshold amount or when the load is higher than a pre-set value, a main contact of the circuit breaker is disconnected and power supply is stopped. Through the intelligent ammeter, electric charge risk is effectively reduced, electricity utilization of a user can be more transparent and safer.
Description
Technical field:
The utility model belongs to power industry Electric Energy Metering Technology field, specifically relates to a kind of intelligent electric energy meter.
Background technology:
Spread in China applying high voltage user electric energy meter is without expense control formula or remote bill control formula at present.
Without taking control formula electric energy meter in use, need to regularly according to electricity charge withholding rule, collect the electricity charge that user need to pay by the staff of management electric energy department, the electricity charge are reclaimed to exist and are in arrears with problem, have electricity charge risk.
Remote bill control formula electric energy meter refers to that power marketing department, by centralized meter-reading system network, completes expense control process; Remote bill control due to centralized meter-reading system networking have relatively high expectations, build complicated.
Utility model content:
The technical solution of the utility model is:
A kind of high pressure local charge control intelligent electric energy meter; comprise: supply unit, measuring screen, protection screen and release unit; supply unit is connected with measuring screen and protection screen by release unit, is arranged in parallel gauging table tripping operation normal opened contact and load meter tripping operation normal opened contact in measuring screen.
A kind of charging method of high pressure local charge control intelligent electric energy meter, comprise electric degree deduct fees module, basic charge as per installed capacity module and power factor adjustment charge module, the described electric degree module of deducting fees is reduced power cost in real time, described basic charge as per installed capacity module per diem/reduce basic charge as per installed capacity by the moon, described power factor adjustment charge module is monthly the name day is reduced the electricity charge of reducing of power factor adjustment charge.
The utility model has the advantage of:
Realize the control of high pressure subscriber's local expense: by coordinating with primary cut-out or relay protection secondary circuit, realize electric energy meter and send breaker tripping and closing signal, really realize local charge control.
Accompanying drawing explanation:
Fig. 1 is that primary cut-out of the present utility model or relay protection secondary circuit are controlled the intelligent electric energy meter schematic diagram that closes, trips;
Embodiment:
Electric energy meter of the present utility model is mainly by controlling closing, tripping of electric energy meter with coordinating of primary cut-out or relay protection secondary circuit.Referring to Fig. 1, ac power supply apparatus is connected with measuring screen and ferrotitanium one line, ferrotitanium two wires protection screen by circuit breaker trip coil.In measuring screen, be arranged in parallel gauging table tripping operation normal opened contact 1 and load meter tripping operation normal opened contact 2.Tripping operation output clamping and protective device tripping operation guard relay are set in ferrotitanium one line, ferrotitanium two wires protection screen; tripping operation output clamping is LP1-pressing plate; described tripping operation output clamping is respectively ferrotitanium one line and the standby pressing plate of ferrotitanium two wires protection screen; described tripping operation output clamping is according to the electric energy meter action of signaling, and plays to control that high-pressure side disconnector disconnects or closed effect.
When electric energy meter remaining sum is during lower than the overdraw thresholding amount of money, the closed connection of gauging table tripping operation normal opened contact, the circuit breaker trip coil motion of power drives series connection, disconnects isolating switch main contacts to realize to stop power supply.The maximum overdraw amount of money that the described overdraw thresholding amount of money is used for allowing user.
When load surpasses predetermined value, load meter trips, and normal opened contact is closed to be connected, and the circuit breaker trip coil motion of power drives series connection makes isolating switch main contacts disconnect realization and stops power supply.
When electric energy meter shows tripping operation, can send trip signal, trip signal is controlled high-pressure side disconnector by relay protection secondary circuit and is disconnected, and before electric energy meter sends permission switching signal, high-pressure side disconnector does not allow closure.
According to electric energy meter of the present utility model, utilize intelligent electric energy meter internal module to control high pressure subscriber's local expense regulatory control.This internal module is according to State Grid Corporation of China's intelligent electric energy meter technical manual, comprises electric degree deduct fees module, basic charge as per installed capacity module and power factor adjustment charge module.The electric degree module of deducting fees is reduced power cost in real time.Basic charge as per installed capacity module per diem/reduce basic charge as per installed capacity by the moon.Power factor adjustment charge module is monthly the name day is reduced the electricity charge of reducing of power factor adjustment charge.Basic charge as per installed capacity module can also be the in the situation that of business change, according to regulation > > changes such as < < power supply and business rules, calculate basic charge as per installed capacity, then the rule of deducting fees in electric energy meter program is modified.
Modification is deducted fees after rule, amended rule need to be imported in intelligent electric energy meter.The regular method of deducting fees of revising intelligent electric energy meter is, by electric energy meter RS-485 PORT COM, by computer program, to be modified.
In intelligent electric energy meter, be inserted with SIM card, realize communication warning function.When electric energy meter, uncap etc. when abnormal, the software program of electric energy meter can send note to default keeper's phone number by the SIM card of installing in table, and when electric energy meter remaining sum is during lower than the preset amount of money, this electric energy meter sends alarming short message to user.
10 kilovolts and above massive quantity power supply and measurement user; the type intelligent electric energy meter is installed; coordinate primary cut-out or relay protection secondary circuit; can realize local charge control; electric energy meter can accurate-metering; reduce basic charge as per installed capacity, power factor adjustment charge, power cost and change and reduce the corresponding electricity charge according to business, can pass through in advance SMS notification user or keeper simultaneously.Can effectively reduce electricity charge risk, make user understand in real time electricity consumption situation simultaneously, electricity consumption is more transparent, protection user and power supply enterprise's legitimate interests.
