Background

The lightning arrester is one of important electrical equipment for protecting power equipment from lightning in a power system, the state of the lightning arrester also affects the safe operation of the power system, but the state of the lightning arrester cannot be known after the lightning arrester is installed and operated. The existing lightning arrester monitoring equipment can only measure the lightning arrester in a state of line power failure or alternatively. In order to avoid the line being affected by the deterioration of the lightning arrester, the power supply company will periodically rotate the lightning arrester. However, the lightning arrester is high in periodic alternation cost, high in labor intensity, long in power failure monitoring time and the like, is not favorable for stable operation of a power grid, and is not in line with the development direction of modern smart power grids.

The current development situation of a 10kV distribution network is that the lightning arrester is used in more and more lines, and the wide use of the lightning arrester increases the workload of operation and inspection personnel. In addition, more lightning arresters cannot be monitored and judged quickly in appearance, great difficulty is brought to operation and maintenance of operation and maintenance personnel, and overhaul efficiency and power supply reliability are seriously affected. If the arrester breaks down in operation, usually need a large amount of manual work investigation just can be accurate find the fault point, the period is wasted time and energy, and very influences power supply quality and user experience. The existing lightning arrester monitoring device is used more in a transformer substation, and the wiring in the transformer substation is more convenient; the 10kV lightning arrester monitoring equipment is generally only used during line maintenance, has the characteristics of large volume, large power consumption and the like, and is generally difficult to erect on a line for a long time.

The existing monitoring device monitors the leakage current of the zinc oxide arrester by an external micro-current sensor, but the monitoring mode has the defects that the detected leakage current is the internal leakage current of the zinc oxide and the surface leakage current outside the arrester.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

Examples

As shown in fig. 1, an arrester with a monitoring device includes an arrester 11, a monitoring terminal and a data processing terminal connected to the arrester 11, where the monitoring terminal includes a temperature sensor, a lightning current collecting module and a micro-current sensor, the temperature sensor is disposed in the middle of a body portion of the arrester 11 and is used for monitoring the temperature of a zinc oxide valve plate inside the arrester 11, so as to accurately detect the state of the arrester 11 and the temperature of a zinc oxide valve plate group inside the arrester 11, thereby accurately detecting the state of the arrester 11; lightning current acquisition module and little current sensor all set up the bottom in the arrester 11 body.

The monitoring terminal also comprises a communication module which is used for transmitting the data detected by the temperature sensor, the lightning current acquisition module and the micro-current sensor to the communication module of the data processing terminal in a communication way. The data processing terminal can generally adopt a computer to receive information, collect and arrange the information and monitor the state of the lightning arrester 11 in real time.

The communication module is an internet of things communication module, adopts an NB-Iot networking mode, is independent of networking, has smaller power consumption than 4G, effectively optimizes a monitoring mode and reduces power consumption, so that the size of the power module can be further reduced, the installation mode is the same as that of a common 10kV line arrester 11, and the application range of the power module is ensured. Meanwhile, an encryption module can be additionally arranged in the process of transmitting information by the communication module, so that the information can be effectively prevented from being leaked.

The monitoring terminal further comprises a power module and a charging module. The power module can adopt a lithium battery and can be charged circularly so as to avoid the problem that the power module needs to be replaced and maintained frequently. The charging module can specifically adopt the photovoltaic panel 33 to utilize solar energy to charge for the lithium cell, in the morning, can directly charge for the lithium cell or for the device directly provides electric power, and in evening or cloudy day, then accessible lithium cell electricity generation maintains the operation of device.

As shown in fig. 2 and 3, in particular, the monitoring terminal part is integrally installed at one side of the bottom of the body of the arrester 11, and includes a housing 22 and a power module arranged inside, a solar panel is arranged at the top of the housing 22, the solar panel is connected with the monitoring terminal part to provide power for the monitoring terminal and charge the power module, and an antenna 44 for transmitting information is arranged at the side of the solar panel.

This application places zinc oxide arrester 11's bottom in with little current sensor in, can avoid the outside surface leakage current of arrester 11 to the influence of monitoring result. In addition, research shows that the temperature of the zinc oxide can also directly reflect the current state of the zinc oxide valve plate, so that a temperature sensor is added to monitor the temperature of the zinc oxide. The purpose of more accurately judging the state of the lightning arrester 11 is achieved by adding a temperature sensor and a leakage current monitoring sensor in a built-in mode.

The problems that the existing lightning arrester 11 monitoring equipment cannot perform online monitoring and is large in size and small in application range are solved. And a wired network with high cost and complex wiring is abandoned. And an NB-IoT Internet of things mode with lower power consumption than that of 4G is adopted for networking. And the NB-IoT is networked based on the existing operator network, and can directly upload the acquired data to the cloud without deploying a gateway on site.
