Abstract
The utility model discloses a low-tension electricity charging control device, which comprises a prepaid electric meter WH and a control circuit. In the control circuit, wherein the prepaid electric meter WH is connected in series with a winding of an intermediate relay ZJ, wherein one end of the series line is connected with a live wire L through a fuse RD1, and the other end is connected with a null line N; a normally open contact ZJ1 of the intermediate relay ZJ is connected with the live wire L through the fuse RD1, and the other end is connected with an input end of a silent running electric appliance WJ; the other input end of the silent running electric appliance WJ is connected with the null line N; two output ends of the silent running electric appliance WJ are connected with two ends of the winding of an AC contactor CJ. The low-tension electricity charging control device has the characteristics that the device is applied to the low-tension electricity which is less than 1000KV, the electrifying and the service interruption are controlled by remote operation, the operation time is short, no noise is produced, less heat productivity is generated on the winding, the electricity is saved, the service life is long, and the operation is safe and reliable.
Description
Technical field
The utility model belongs to transmission line of electricity charging control technology field, especially relates to a kind of low tension charging control device.
Background technology
Present electricity consumption electricity metering, the general mode that adopts pre-payment and back to pay, adopt the metering method of pre-payment, adopt pre-paying kilowatt-hour meter usually, after the user pays dues, department opens supply line by electric industry, after expense was finished using, power supply finished, when needing to continue power supply, the general employing continues to pay dues before the electricity charge use up, but continue to pay dues when the user forgets, when outage takes place, need the manual control on-site manual to connect, such one is that the time is long, influence user's electrification, the 2nd, manually connect switch, danger is bigger, personal property loss can take place in misoperation.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides the following low tension of a kind of suitable 1000KV, remote control to control power on/off, running time weak point, noiselessness, avoid coil heating, economize on electricity, long service life, the reliable low tension charging of handling safety control device.
The purpose of this utility model is to realize like this, a kind of low tension charging control device, form by pre-paying kilowatt-hour meter WH and control circuit, be characterized in that control circuit is that pre payment watthour meter WH connects with the coil of intermediate relay ZJ, one end is through the fuse RD1 line L that starts to exchange fire, other end connecting to neutral line N, normally closed contact ZJ1 one end of intermediate relay ZJ is connected to live wire L through fuse RD1, the other end is connected to the input end of silent running electrical equipment WJ, another input end connecting to neutral line N of silent running electrical equipment WJ, the two ends of the two output termination A.C. contactor CJ coils of silent running electrical equipment WJ.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts auxiliary reclay, silent running electrical equipment and DTSB pre-paying kilowatt-hour meter constitute, the DTSB ammeter has the wireless receiving emission function, the utility model utilizes the wireless transmit receiving function of DTSB ammeter, Remote DTSB ammeter, reach and do not have expense outage automatically, has perfect remote control " warning " remote signalling, anti-electricity-theft, the function of anti-error of omission, after continuing to pay dues, the purpose of Remote Control Automatic connection, simple in structure, control convenient and reliable, not only reduce cost but also ensured safety, adopted silent running electrical equipment, reached noiselessness, reduce the coil heating of A.C. contactor, the economize on electricity and increase the service life, the utlity model has the small volume structure compactness, be applicable to indoor, characteristics such as outer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of electronic-circuit diagram of the utility model control circuit.
Embodiment
Embodiment, a kind of low tension charging control device, with reference to Fig. 1, pre-paying kilowatt-hour meter WH and control circuit are formed, control circuit is that pre payment watthour meter WH connects with the coil of intermediate relay ZJ, one end is through the fuse RD1 line L that starts to exchange fire, other end connecting to neutral line N, normally closed contact ZJ1 one end of intermediate relay ZJ is connected to live wire L through fuse RD1, the other end is connected to the input end of silent running electrical equipment WJ, another input end connecting to neutral line N of silent running electrical equipment WJ, the two ends of the two output termination A.C. contactor CJ coils of silent running electrical equipment WJ, pre-paying kilowatt-hour meter is the DTSB pre-paying kilowatt-hour meter, and this constitutes a kind of structure of the present utility model.
When using the utility model, this device is connected on not to be had the expense back of reporting to the police and sends power cut signal by pre-paying kilowatt-hour meter WH on the transmission line of electricity between power supply administration and user, the coil power of intermediate relay ZJ gets, the normally closed contact ZJ1 of intermediate relay ZJ disconnects, the input end dead electricity of silent running electrical equipment WJ, A.C. contactor CJ coil losing electricity, A.C. contactor CJ disjunction disconnects user's transmission line of electricity and power supply administration's transmission line of electricity; After continuing to pay dues, pre-paying kilowatt-hour meter WH sends when recovering to send electric signal, the coil losing electricity of intermediate relay ZJ, the normally closed contact ZJ1 closure of intermediate relay ZJ, the input end of silent running electrical equipment WJ gets, A.C. contactor CJ coil gets electric, A.C. contactor CJ adhesive, and the transmission line of electricity that makes the user is communicated with power supply with the power supply administration transmission line of electricity.
