Description

Technical Field

[0001] The invention relates to the technical field of leakage protection and detection, and in particular to a power switch cabinet with a leakage protection mechanism and a leakage detection system thereof. Background Art

[0002] Power switchgear can be divided into high-voltage switchgear and low-voltage switchgear according to the voltage level of the incoming and outgoing lines. High-voltage switchgear is usually used in power systems of 10kV and above, while low-voltage switchgear is used in power systems of 400V and below. The composition of power switchgear includes vacuum circuit breakers, disconnectors, current transformers, voltage transformers, lightning arresters and other components. The main function of the power switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The power switchgear ensures the reasonable distribution and use of electric energy by distributing electric energy from the power source to each load point. For example, the incoming line cabinet is responsible for introducing power from the outside and sending electric energy to the busbar, and the outgoing line cabinet is responsible for distributing electric energy to each load point; the power switchgear can control the circuit. Segmented control allows the power system to be quickly isolated in the event of a fault, improving the flexibility of the system. The semiconductor components of the switchgear have the advantages of fast switching speed and low energy consumption, reducing the switching loss of the system and improving the efficiency of the system. The switchgear is also very convenient to maintain. Once a fault occurs, only the faulty component needs to be replaced without overhauling the entire system, greatly shortening the maintenance time. Currently, power switchgear is widely used in power, metallurgy, chemical industry, construction and other fields. In the power system, switchgear is used for power distribution and control to ensure the safe and stable operation of the power system. In factories and enterprises, switchgear is used to control mechanical equipment to ensure the normal operation of the production line. In the construction field, switchgear is used to control lighting, air conditioning and other facilities to improve the intelligence level of the building.

[0003] However, the traditional power switch cabinet cannot meet people's needs, and it has the following defects: First, the existing leakage protection mechanism cannot effectively monitor each different terminal of the power switch cabinet, and can only judge whether the power switch cabinet is in an abnormal state according to the real-time situation. It is impossible to quickly confirm the specific abnormal position when it is abnormal, which reduces the practical effect of the leakage protection mechanism. It is necessary to manually confirm all lines of the abnormal switch cabinet, which increases the time required for subsequent maintenance; second, there is no automatic lighting device designed. At night or in an environment with insufficient lighting, the operator cannot effectively confirm the operating status of the power switch cabinet, and manual lighting is required, which increases the difficulty of detection for the operator, and cannot guarantee the authenticity and effectiveness of the detection, which increases the investment in detection costs; third, there is no data preprocessing module designed. For the collected circuit signals, signal processing needs to be centralized. The huge amount of data increases the difficulty of terminal operation, and contains a large amount of invalid data or incomplete data, which makes the subsequent calculation and analysis results different, which may cause errors in subsequent judgments, and to a certain extent reduces the accuracy of the leakage detection system.
