Meter box anti-electric device technical parameters

I. Overview

With the rapid development of the economy and the increasing use of electricity, the problem of power theft has become more and more prominent in many areas. Inverting, bridging, counterfeiting seals, and the use of counters, etc. Intelligentization has caused power companies to suffer huge economic losses.

In order to effectively prevent the occurrence of power theft and reduce the losses of the power supply company, the company has developed a meter box anti-tampering device that is mainly used to generate alarms and power failures in case of abnormal opening of metering boxes and meter boxes.

　 Second, introduction

The meter box anti-tampering device adopts the Internet of Things and wireless communication technology. It installs an intelligent anti-tampering device inside the electricity meter box or the meter box of the suspected user to realize the on-line monitoring of the power consumption end, which can effectively prevent the stealing of electricity. Occurs and reduces the losses of the power company. The system is divided into two parts: the front-end anti-theft device for Internet of Things and the central management platform. The anti-theft terminal uses GPRS and the central platform for communication.

The device is compact and easy to install and has high reliability. The system has a GSM module and uses SMS to report the alert. This system uses encryption technology, security, and high confidentiality. The alarm device design fully considers the anti-jamming condition under the complex electromagnetic environment. With software filtering, software traps, watchdog, RC absorption, electromagnetic shielding and other functions. Suitable for a variety of occasions.

Fourth, the main function

1. On-line monitoring function of the switch state of the watch cabinet door;

2. The validity test function of the meter box switch;

3, table box leakage and power stealing online monitoring;

4, power failure automatic reminder function;

5, remote power off function;

6, meter reading and inspection management personnel in place rate monitoring;

7, real-time power collection function;

8, personnel remote authorization and data storage capabilities;

9, online detection equipment.

V. Main features of electrical devices:

1. The key management of the electronic key can be used to determine the legality and illegality of opening the distribution metering box. If it is opened illegally, it will be tripped and power failure.

2, can also use a dedicated authorized mobile phone can be opened by SMS certification, if forced to open the meter box for power supply, it will immediately trip power outages, and the incident reported to the center via SMS. 3. Any operation performed by the user in the power distribution room will not affect normal power supply and metering.

4. Power cuts and transmissions from the upper power grid do not affect the normal operation of the device.

5, the control device is non-detachable overall, no external wiring, can effectively prevent vandalism.

6. Any event of unpacking, power failure, and power supply recovery will be reported to the network management and alarm center.
