Abstract
The utility model relates to a compact-type high-voltage prepayment device. The prepayment device comprises a box body which is divided into a wire inlet cabinet, a measuring cabinet and a wire outlet cabinet by partition boards; a three-phase inlet wire is led into the box body, sequentially passes the wire inlet cabinet, the measuring cabinet and the wire outlet cabinet, and is then led out; the three-phase inlet wire in the wire inlet cabinet is connected in series with a sulfur hexafluoride switch, and connected in parallel with a lightning arrester, a sensor and a voltage transformer with a fuse; the three-phase inlet wire in the measuring cabinet penetrates a current transformer and is connected in parallel with a sensor and a voltage transformer with a fuse; and the three-phase inlet wire in the wire outlet cabinet is connected in series with a vacuum circuit breaker and connected in parallel with a sensor and a lightning arrester. In the utility model, the protective combination of the sulfur hexafluoride switch and the vacuum circuit breaker is adopted, so that the prepayment device has the advantages of small overall size, light weight, compact structure and the like. The compact type high-voltage prepayment device can serve as a movable prepayment high-voltage switchyard.
Description
Technical field
The utility model relates to the device field that high pressure is surveyed electric energy metrical, is specifically related to a kind of compact high-voltage prepayment device.
Background technology
The high-voltage prepayment device is made of high-pressure vacuum breaker and electric current, voltage combination transformer and ammeter box, and pre-paying kilowatt-hour meter and ON-OFF control circuit are housed in the ammeter box.
Electric weight in input user forward purchasing after pre-payment controller is confirmed, sends the permission switching signal, and the pre-payment special switch can close a floodgate, and powers to the user.
When making power consumption reach the setting value of user prepayment electric weight, device sends the due alarm automatically, and warning can be set to the buzzing mode, after the user confirms, reports to the police and eliminates; When making power consumption reach the user to buy electric weight, the pre-payment control device is operated automatically, pre-payment special switch separating brake, user's outage (this moment, isolating switch was in the outage lock-out state); After the user buys electric weight again, release again, the power supply of closing a floodgate.The metering ammeter can use pre-payment type electronic watch by customer requirements.
