Description

Technical Field

[0001] The utility model relates to the field of electrical equipment port protection, in particular to a cover protection structure for electrical equipment connection ports. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. When using electrical equipment, it is usually necessary to plug in cables and operate buttons to operate the electrical equipment. Therefore, connection ports are opened on the outer panels of the electrical equipment.

[0003] For example, all live parts of the gas-insulated switchgear are isolated in a sealed stainless steel gas box filled with SF6 gas, which can provide an integrated power equipment unit for connecting, disconnecting or feeding the cable line. It is suitable for indoor and outdoor substations and can operate stably in industrial environments, humidity, sand and dust, low temperature and other extremely harsh environmental conditions. Usually the main bus current is greater than or equal to 1250A and is used in substations.

[0004] Ring main box, also known as box-type ring main cabinet, refers to an outdoor integrated power equipment unit that can provide connection, disconnection or feeder for cable lines. In its product solution, load switches are mainly used as the main components for line disconnection. They have the ability to disconnect working current, which is different from switch stations and branch boxes.

[0005] Whether it is a gas-insulated switchgear or a ring network box, the connection port needs to be connected to the outside world. However, when not in use, the connection port needs to be protected. The anti-misoperation cover in the industry is usually a plastic padlock device, which is not strong enough. When the cabinet is installed on site, the panel will be taken down and stacked together, which will cause the plastic padlock device to be crushed and the padlock cannot be hung. A new padlock device needs to be replaced, which is time-consuming, labor-intensive, and costly, and delays the construction period.

[0006] The patent with patent announcement number CN 216981205 U discloses a padlock device for the operating hole of the grounding switch of an electrical cabinet, which is used to install a padlock at the corresponding position of the operating hole of the grounding switch of the electrical cabinet, and includes a padlock component, which includes: a mounting assembly, which includes a mounting block mounted at the position of the operating hole of the grounding switch of the electrical cabinet; a hinge assembly, which includes a hinge block pivotally mounted on the mounting block, and a hinge connector movably arranged on the hinge portion; a clamping assembly, which includes clamping blocks symmetrically arranged on both sides of the hinge connector and an elastic member used to drive the hinge connector to abut against the mounting connector. The utility model can switch the opening and closing state of the grounding switch lock piece by flipping the hinge block relative to the mounting block to a disengaged state, and can lock the lock piece of the grounding switch by flipping the hinge block relative to the mounting block again to a fitted state, and at the same time, the clamping assembly makes the connection between the hinge block and the mounting block more stable.

[0007] The above-mentioned device limits the grounding switch by setting an I-shaped limit hole to prevent unauthorized personnel from operating it incorrectly. However, the structure is complex and the operating procedures are cumbersome, which increases the cost of use. In addition, when encountering an emergency during actual work, the steps from opening the padlock to opening the hinge assembly and finally pressing the operating switch are relatively cumbersome. When the device fails or a fire occurs, the opening and closing operations cannot be performed quickly, which greatly increases the accident rate and affects the personal safety of the operator.
