ZW □ TF1-12 outdoor vacuum intervention payment anti stealing device

1、 Overview

In order to meet the needs of power consumption management and use technical means to solve the difficulty of electricity charge recovery, especially the large amount of large power users and difficult to control, the company has developed ZW port tf1-12 outdoor vacuum intervention payment anti-theft device. This product is applicable to AC 50Hz, 6 - 10kV power system as an automatic recloser in prepaid high-voltage metering or distribution network automation engineering. The host is composed of ZW8-12 vacuum circuit breaker, dry-type voltage transformer for metering, current transformer, etc. it is installed integrally. The upper part of the box is a vacuum circuit breaker, the lower part is a transformer room, and the outside is equipped with a manual opening and closing spring mechanism, Split installation of control box,

Prepayment meter can be added as prepayment measurement according to the user's requirements, and the prepayment meter can also be installed by the user. The high voltage vacuum circuit breaker is a spring mechanism with mechanical locking. The box is divided into switch room and transformer room.

The transformer room is composed of two dry-type voltage transformers and two dry-type current transformers. The voltage transformer is equipped with special windings as the power supply of the opening and closing mechanism of the circuit breaker. Its overall shape is small and easy to install.

Voltage transformer VN wiring, current transformer can be made into variable ratio structure to meet the needs of different loads. The control device is composed of prepaid electricity meter and circuit breaker control circuit. The control device and vacuum switch are connected with each other, and metal armored cables are used to effectively realize the function of purchasing electricity before use, and effectively avoid the phenomenon of arrears of electricity charges.

3、 Technical parameters

4、 Main features

◆ the system is composed of high-voltage metering control device and vacuum circuit breaker. It is matched with other electrical equipment such as disconnector and lightning arrester, and can complete the power metering and pre purchase of high-voltage direct supply users.

◆ use electric energy meter for measurement and settlement.

◆ users can buy electricity first and then use electricity through power purchase card. Each metering box is equipped with a special power purchase card, which is not common to each other.

◆ the power purchase data is valid at one time, automatically erased after the card is inserted and confirmed, and has the functions of anti magnetism and anti-static and can not be deciphered after encryption.

◆ after inserting the card for power transmission, the user can pull out the card and keep it properly for use in the next power purchase. If the power purchase card is damaged or lost, the user can go to the power sales department to make up the card according to the user's file.

◆ the user can view the remaining power, used power and other power consumption parameters through the device display screen at any time.

◆ when the remaining power reaches the alarm threshold, it has audible and visual alarm to remind users to purchase power in time.

◆ when the power purchase of the device is zero, it can reliably disconnect the load current of users, so as to solve the problem of long-term arrears of electricity charges.

◆ anti electricity theft function. Since the device adopts outdoor transformer side metering, the meter is installed in a closed professional metering box, which can fundamentally solve the problem of anti electricity theft.
