Example Embodiment

[0028] The intelligent switch cabinet referred to in the present invention refers to a switch cabinet with perception, judgment, and execution functions;

[0029] Perception: Online monitoring realizes real-time monitoring function, namely perception;

[0030] Judgment: After monitoring the data online, perform a diagnosis and compare with the preset value to judge whether it is normal. If it is abnormal, it will alarm. After the alarm is issued, the relevant next step execution instructions are issued in the background or the integrated automation system of the substation.

[0031] Execution: Use a microcomputer to execute.

[0032] The above functions mainly rely on two parts to complete; one is the monitoring part (perception) used to monitor various data signals; the other is the control system that judges and executes the data signals obtained by monitoring. Since the control system is a conventional technology, the present invention is mainly for research and research on the mo...

Abstract

The invention relates to a medium voltage switch cabinet. Aiming at technical problems, the operation state of the switch cabinet provided by the invention can be real-timely monitored, and the switch cabinet has the characteristics of accurate monitoring data and efficient inspection, thus the safe and reliable operation to the switch cabinet can be guaranteed. The switch cabinet adopts the technical scheme that the intelligent medium voltage switch cabinet comprises a cabinet body, copper buses arranged in the cabinet body, a contact box, a circuit breaker and a control system connected with a network, and is characterized by further comprising temperature measuring components used for detecting the temperature of the copper buses, a displacement component used for detecting mechanical characteristics of the circuit breaker and a current guiding component used for detecting the leakage current of an insulated piece; the temperature measuring components, the displacement component and the current guiding component are respectively accessed into the control system via data lines for uploading acquired data, further the real-time monitoring of the operation state of the switch cabinet and seamless connection of the switch cabinet with relative systems are achieved.

Description

technical field [0001] The invention relates to a metal-enclosed switchgear and control equipment in a power transmission system, in particular to a medium-voltage switchgear. Background technique [0002] The medium-voltage switchgear is an important electrical equipment in the power transmission system. The external current first enters the main control switch in the cabinet through the wire, and then enters the sub-control switch to connect with each branch; each branch needs to be equipped with instruments, control and protection components , monitoring components, various AC circuit breakers and other control components, control, protect, measure, measure, monitor, etc. the circuit. [0003] With the increase of service time, the operating state of the switchgear will gradually deteriorate, and various signs of failure will gradually appear; for example, the conductive connection inside the switchgear will cause contact conditions due to electrical wear, mechanical vibr...
