Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to an intelligent switch cabinet. Background Art

[0002] In order to ensure power safety and improve personal and equipment safety, according to the "National Grid Company's Safety Management Regulations on Preventing Electrical Misoperation", electrical equipment (high-voltage switchgear) is required to have five anti-misoperation functions, among which preventing accidental entry into live compartments is the key. Most of the existing switchgear can meet the requirements of the five protections, but they still have at least the following defects:

[0003] (1) To prevent electricity theft, most cabinets use sealed handles. Only authorized personnel can break the seals and open the cabinet, thereby authorizing the operation of the circuit breaker room door. In the power industry, this operation authorization (i.e., the record of authorized personnel, operators, and operation time) is almost always completed using paper operation tickets. This method often fails to achieve accurate records and is prone to record loss and tampering.

[0004] (2) The authorization of the circuit breaker trolley crank handle hole cover switch operation is also completed by using a paper operation ticket, which makes it easy for unauthorized personnel to operate the switch cabinet. Unauthorized personnel can change the position status of the circuit breaker at any time, which poses a certain safety hazard.

[0005] (3) The authorization for opening the cabinet and operating the handle hole cover switch is often approved manually, which easily leads to inconsistency between the authorized personnel and the actual operator, making it difficult to implement the safety regulations of the customer's actual operation and ensuring safe and reliable operation of the switch equipment.

[0006] (4) In most current switchgear, an interlocking mechanism is only provided between the switch cabinet door and the circuit breaker trolley. This interlocking mechanism prevents the cabinet door from being opened when the circuit breaker trolley is in the working position. The cabinet door can only be opened when the circuit breaker returns to the test position. However, an interlocking mechanism is rarely provided between the circuit breaker room door and the circuit breaker trolley. When the cabinet door is in the open state during maintenance and overhaul, the circuit breaker room door can be opened at will regardless of whether the circuit breaker trolley is in the working state. If the circuit breaker room door is opened accidentally and a short circuit occurs in the circuit breaker room, the arc and high-pressure gas generated in the circuit breaker room will endanger personal safety, posing a major safety hazard.
