Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a double-door structure for an emergency power supply incoming line compartment and a fully insulated ring network cabinet. Background Art

[0002] The emergency power supply compartment on the fully insulated ring main unit is a device designed to provide power in emergency situations. When a power system fails or a power outage occurs, in order to ensure that important loads can continue to be powered, it is necessary to quickly and reliably access the emergency power supply. The emergency power supply compartment is designed for this purpose.

[0003] In the related art, an emergency power supply incoming line compartment includes a compartment body and a compartment door installed on the compartment body. The interior of the emergency power supply incoming line compartment is usually equipped with a quick access device, which can connect the emergency power supply to the ring main unit in a short time to ensure the continuity of power supply. When the emergency power supply needs to be connected to the inside of the ring main unit, the compartment door is opened first, and then the external cable is connected to the quick access device through the opening of the compartment door.

[0004] In order to avoid interference with the cables connected to the inside of the ring network cabinet, it is necessary to keep the compartment door open as a whole during the emergency power supply process. However, since the door is open, the quick access device will also be directly exposed and in direct contact with the outside world. At this time, the compartment door cannot protect the quick access device or other electrical components inside the compartment. Unauthorized persons may accidentally touch the internal electrical components, posing a safety hazard. Utility Model Content

[0005] The purpose of the present application is to provide a double-door structure for an emergency power supply incoming line compartment and a fully insulated ring network cabinet, so as to solve the problem in the above-mentioned related technology that, due to the need to keep the compartment door open as a whole during the emergency power supply process, the quick access device is also directly exposed and in direct contact with the outside world. At this time, the compartment door cannot protect the quick access device or other electrical components inside the compartment body, and unauthorized persons may accidentally touch the internal electrical components, posing a safety hazard.

[0006] The double-door structure of the emergency power supply warehouse provided in this application adopts the following technical solution:

[0007] A double-door structure for an emergency power supply incoming line warehouse, comprising a warehouse body, wherein a connecting port communicating with the interior of a ring network cabinet is provided on the upper side of the warehouse body; an incoming line port is provided on the side of the warehouse body, a protective door is hingedly connected to the vertical edge of the upper part of the incoming line port of the warehouse body, a lock is installed on the protective door, an emergency door is hingedly connected to the horizontal edge of the lower part of the incoming line port of the warehouse body, a limit strip is provided on the side edge of the protective door close to the emergency door, and a limit slot is provided on the emergency door for the limit strip to be rotatably placed.

[0008] By adopting the above technical solution, when the emergency power supply needs to be connected to the inside of the ring network cabinet, the protective door is unlocked, and the user pulls the handle to pull the protective door to rotate in the vertical direction. At this time, the emergency door can be turned to rotate downward. After the emergency power supply is connected, the protective door is closed and locked alone. At this time, the lower part of the line inlet is connected to the outside world to make way for the connected cables, but the upper part of the line inlet is closed by the protective door to prevent the quick access device inside the warehouse from being directly exposed to the air, thereby protecting the quick access device or other electrical components inside the warehouse, thereby reducing the safety hazards that may arise due to the quick access device or other electrical components inside the warehouse being exposed to the outside.

[0009] Optionally, a first traction rod and a second traction rod hinged to each other are provided on the side of the bin body, one end of the first traction rod is hinged to the side of the bin body, and one end of the second traction rod is hinged to the inner side of the emergency door.

[0010] By adopting the above technical solution, during the opening of the emergency door, the first traction rod and the second traction rod are unfolded, but the overall length of the first traction rod and the second traction rod is limited, thereby limiting the downward rotation range of the emergency door and reducing the possibility of the emergency door colliding with the ground when flipping downward.

[0011] Optionally, a first magnetic block and a second magnetic block that attract each other are provided on the side of the warehouse body, a first installation groove for the first magnetic block to be embedded in is opened on the limit bar, and a second installation groove for the second magnetic block to be embedded in is opened on the side wall of the limit groove.

[0012] By adopting the above technical solution, when the protective door limits the emergency door, the limit bar is rotated and placed into the limit groove through the installation of the first magnetic block and the second magnetic block, and at the same time, the sides of the first magnetic block and the second magnetic block that are close to each other are fit together, thereby improving the installation stability of the limit bar in the limit groove and reducing the possibility of the emergency door loosening relative to the protective door in the limited state.

[0013] Optionally, an air inlet is opened on the side of the warehouse body, and an exhaust fan is installed on the outer edge of the air inlet of the warehouse body.

[0014] By adopting the above technical solution, when the emergency power supply is connected to the interior of the warehouse, the temperature at the connection between the cable and the quick access assembly device in the warehouse is high. At this time, the exhaust fan is started to inject the external gas into the interior of the warehouse through the air inlet, so that the high-temperature gas inside the warehouse is discharged from the lower opening of the line inlet, thereby realizing the rapid exchange of gas inside and outside the warehouse, improving the heat dissipation performance of the line inlet warehouse, and reducing the possibility of failure due to excessive temperature inside the warehouse.

[0015] Optionally, an air duct is installed at the inner opening edge of the air inlet of the warehouse body, and the opening direction of the air duct is inclined downward.

[0016] By adopting the above technical solution, since the opening of the air duct is inclined downward, when the outside air enters the cabinet through the air inlet, the outside air is guided by the air duct so that the outside air is blown toward the lower part of the inner cavity of the bin, which facilitates the discharge of the gas inside the bin from the lower opening of the inlet port, thereby facilitating the exchange of internal and external gases and further improving the heat dissipation efficiency of the inlet bin.

[0017] Optionally, a filter cover is installed at the opening of the air duct, and a dust filter is installed in the middle of the filter cover.

[0018] By adopting the above technical solution, due to the setting of the filter cover, when the external air enters the interior of the warehouse through the air inlet and the air duct, it will be further screened by the dust-proof filter on the filter cover to screen out the dust that may be carried in the external air, thereby reducing the possibility of external dust being injected into the interior of the warehouse through the air inlet and the air duct.

[0019] Optionally, a fixing ring is provided on one side edge of the filter cover and is threadedly sleeved on the outer peripheral surface of the air duct opening.

[0020] By adopting the above technical solution, due to the setting of the fixing ring, the fixing ring thread can be sleeved on the outer peripheral surface of the end of the air duct, which is convenient for installing the filter cover and also convenient for removing the filter cover from the air duct, which is beneficial to cleaning the dust filter on the filter cover.

[0021] Optionally, a fixing flange is provided at the end of the air guide tube close to the bin body, and a fixing groove is provided at the inner opening edge of the bin body at the air inlet for the fixing flange to be inserted and fixed by bolts.

[0022] By adopting the above technical solution, when fixing the air duct to the inner wall of the bin, the fixing flange is first inserted into the fixing groove on the inner wall of the bin, and then further locked with bolts, thereby improving the installation stability of the air duct.

[0023] A fully insulated ring main unit comprises any one of the emergency power supply incoming line compartment double-door structures described in item 1.

[0024] By adopting the above-mentioned technical solution, when the double-door structure of the emergency power incoming line compartment is applied to a fully insulated ring main unit, it is possible to protect the quick access device or other electrical components inside the compartment, thereby reducing the potential safety hazards that may arise due to the quick access device or other electrical components inside the compartment being exposed to the outside.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the separate setting of the protective door and the emergency door, after the emergency power supply is connected, the protective door can be closed and locked separately, and the emergency door can be opened. At this time, the lower part of the cable inlet is connected to the outside world to make way for the connected cables, but the upper part of the cable inlet is closed by the protective door to prevent the quick access device inside the warehouse from being directly exposed to the air, thereby protecting the quick access device or other electrical components inside the warehouse, thereby reducing the potential safety hazards caused by the quick access device or other electrical components inside the warehouse being exposed to the outside.

[0027] 2. Through the installation and arrangement of the first magnetic block and the second magnetic block, when the protective door limits the emergency door, the limit bar is rotated and placed into the limit groove, and at the same time, the sides of the first magnetic block and the second magnetic block that are close to each other are fitted together, thereby improving the installation stability of the limit bar in the limit groove and reducing the possibility of the emergency door loosening relative to the protective door in the limited state.
