Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of safety signboard, specifically, a safety signboard for secondary control cabinet operation. BACKGROUND

[0002] In the secondary circuit of power plant and substation, there are a large number of control cabinets (i.e. secondary control cabinet). In the operation, maintenance and repair operation of power plant and substation, the corresponding switches in the secondary control cabinet need to be disconnected according to the electrical work ticket. In order to prevent misoperation caused by the entry and exit of coordination communication information, a safety warning signboard is usually hung on the current disconnected switch to declare the safety information of "prohibit closing, someone is working!" However, the types of switches in the secondary control cabinet are various, the switch specifications are small and densely arranged, the specifications of each switch are the same or similar, and the naming is also similar. Since the safety warning signboard currently used does not have current detection function, the worker cannot intuitively perceive the wrong position when hanging the safety warning signboard in the densely arranged secondary control cabinet switches, and is easy to cause electric shock safety accidents due to misconnection and miswiring in subsequent operation.

[0003] In order to improve the safety of secondary control cabinet operation, it is necessary to set current detection function for safety warning signboard to intuitively judge whether the switch hung with safety warning signboard is in disconnected / connected state. The applicant has searched the prior art and found no safety warning signboard that can detect current for secondary control cabinet.

[0004] A technical solution named "power equipment state signboard" is disclosed in Chinese patent document CN105277775A, published on January 27, 2016. In this technology, the state of power equipment is detected by integrating various sensors and detection devices, and is intuitively displayed by different color indicator lights; however, the structure of this signboard is complex and fixed, which is difficult to adapt to the specific position and demand of each switch in the secondary control cabinet. It can be seen that its flexibility and convenience are low, and it cannot be applied to secondary control cabinet. UTILITY MODEL CONTENT
