Problems solved by technology

[0003] In addition, in freezing weather, transmission lines and towers are often covered with an ice layer, which can easily lead to wire breakage and the collapse of power towers regardless of the load. There is a lack of devices and systems to deal with these potential faults in the current system, so it is necessary to design a new power fault detection system

Embodiment 1

[0058] Such as Figure 1-12 , the power fault detection system has a power quality detection system, including a server, inspection terminals and multiple on-site monitoring terminals;

[0059] The on-site monitoring terminal is fixed at each detection point of the transmission line or substation to detect the voltage and current of the monitoring point; the on-site monitoring terminal transmits the sampled current and voltage information to the server;

[0060] There is a data analysis module in the server, which is used to analyze the power quality of the circuit. The power quality includes determining whether the voltage, current and each harmonic (also known as the distortion rate) exceed the preset value;

[0061] The inspection terminal includes an aircraft, and a camera 4 is arranged on the aircraft; the images and videos collected by the aircraft are sent to the server. The aircraft is used to check whether there is any loosening of the monitoring point or equipment d...

Embodiment 2

[0073] Embodiment 2: A power monitoring method for a substation corresponding to a power fault detection system

[0074] A method for monitoring electric energy in a substation, comprising the following steps:

[0075] Step 1: Data Acquisition

[0076] On-site monitoring terminals set up at each detection point of the substation collect power data;

[0077] The power data includes the instantaneous voltage and current amplitudes collected by voltage transformers and current transformers; the power data can further include the switch state data of each power switch, preferably, detected by sensors, such as detected by angle sensors Whether the switch is in action, or use the camera to take pictures to confirm whether the switch is in action;

[0078] Step 2: Data transfer

[0079] The on-site monitoring terminal transmits the collected power data to the server;

[0080] Step 3: Data Processing and Monitoring

[0081] The server processes the power data and analyzes the vol...

Embodiment 3

[0091] Embodiment 3: Power Fault Detection System

[0092] A power failure detection system, including a server and an ice-breaking robot arranged on a transmission line;

[0093] The ice-breaking robot is equipped with a camera and a remote control signal receiving module; the ice-breaking robot is also equipped with a wireless transmission module;

[0094] The image collected by the camera is uploaded to the server through the wireless transmission module; the server judges whether there is a fault or a potential fault based on the image. If the difference between the diameter of the transmission line and the original diameter exceeds the preset value, it means that there is ice on the transmission line. , there is a potential safety hazard, start deicing.

[0095] The front end of the ice-breaking robot is equipped with an encircling ice-breaking mechanism; the encircling ice-breaking mechanism is composed of two semi-circular components. When the two semi-circular compone...

Abstract

The invention discloses a power failure detection system; the power failure detection system comprises a server and an ice breaking robot arranged on a power transmission line; a camera and a remote control signal receiving module are arranged on the ice breaking robot; the ice breaking robot is further provided with a wireless transmission module; an image collected by the camera is uploaded to the server through the wireless transmission module; the server judges whether a fault or a fault hidden danger exists or not on the basis of the image; a surrounding type ice breaking mechanism is arranged at the front end of the ice breaking robot; the surrounding type ice breaking mechanism is composed of two semi-annular components; when the two semi-annular components are combined, a circularring-shaped ice breaking component can be formed; a plurality of ice breaking units are uniformly arranged at the front end of the surrounding type ice breaking mechanism along the peripheral line; each ice breaking unit is provided with an ice breaking thorn (10) driven by an electromagnet; and the included angle between the ice breaking thorn and the axis of the circular ring-shaped ice breakingcomponent is 10-60 degrees. The electric power fault detection system can detect the electric energy quality in all directions and detect whether the fault hidden danger exists or not, and is easy toimplement.

Description

technical field [0001] The invention relates to a power fault detection system. Background technique [0002] Due to the change of power load and the existence of various short-circuit faults in the power system, the quality of power supply changes, such as voltage drop during peak power consumption, power factor is too small, harmonic component is too large, and current rises significantly when the circuit is faulty. It will affect the stable power supply, so it is necessary to monitor the power quality. [0003] In addition, in freezing weather, transmission lines and towers are often covered with an ice layer, which can easily lead to wire breakage and the collapse of power towers regardless of the load. There is a lack of devices and systems to deal with these hidden faults in the current system. Therefore, it is necessary to design a new power fault detection system. Contents of the invention [0004] The technical problem to be solved by the present invention is to...
