DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] According to the box-type substation of the embodiment of the present invention, the box-type substation includes a top cover 1, a side wall 3 and a base 2. The top cover 1, the base 2 and the plurality of side walls 3 are enclosed to form an equipment cabin. A partition wall 4 is arranged in the equipment cabin. The partition wall 4 separates the equipment cabin to form a high-voltage chamber 6 and a low-voltage chamber 7. A cable channel 5 is arranged at the bottom of the equipment cabin. A high-voltage incoming line terminal 61 and a high-voltage outgoing line terminal 62 are arranged on the side of the high-voltage chamber 6 away from the low-voltage chamber 7. A low-voltage output terminal 71 is arranged on the side of the low-voltage chamber 7 away from the high-voltage chamber 6. Both the high-voltage chamber 6 and the low-voltage chamber 7 are provided with sealed doors 8. A transformer chamber 72 is arranged in the low-voltage chamber 7 for placing a transformer 721. The low-voltage chamber 7 is connected to the air permeable portion 10 on the side wall 3 through a ventilation device 9; the high-voltage incoming line terminal 61 and the high-voltage outgoing line terminal 62 are respectively used to connect external high-voltage incoming line cables and high-voltage outgoing line cables to respectively introduce or lead out high-voltage electric energy, and this side is the high-voltage side. The high-voltage incoming line terminal 61 and the high-voltage outgoing line terminal 62 are arranged on the same side, which can facilitate the connection of the external high-voltage incoming line cable and the high-voltage outgoing line cable. The low-voltage chamber 7 is the low-voltage side, and the low-voltage output terminal 71 is used to connect the external low-voltage outgoing line cable. The high-voltage side and the low-voltage side are arranged on different sides of the substation so that the high-voltage cable and the low-voltage cable will not interfere with each other, which is more convenient for cable arrangement. The two independent high-voltage chambers 6 and low-voltage chambers 7 formed by the partition wall 4 can avoid interference between high-voltage substation equipment and low-voltage substation equipment.

[0023] A high-voltage incoming line cabinet 63, a high-voltage outgoing line cabinet 64, a transformer outgoing line cabinet 65 and a voltage transformer cabinet 66 are arranged in the high-voltage room 6. The transformer outgoing line cabinet 65 is adjacent to the transformer room 72 and is connected through the cable channel 5. The voltage transformer cabinet 66 is connected to the cable channel 5 to monitor the line voltage.

[0024] The low-voltage room 7 is provided with a low-voltage inlet and outlet cabinet 722, a transformer room door; 73 and a distribution box 74, and the low-voltage inlet and outlet cabinet 722, a transformer room door; 73 is electrically connected to the transformer 721 and the distribution box 74 through the cable channel 5. The sealed door 8 can prevent external water and dust from entering the high-voltage room 6 and the low-voltage room 7, and avoid damaging the substation equipment placed in the high-voltage room 6 and the low-voltage room 7, so as to ensure the normal operation of the substation equipment. A transformer room 72 is provided in the low-voltage room 7 to place the transformer 721 separately. The separately arranged transformer room 72 is made of flame-retardant, heat-insulating, dust-proof and waterproof materials, which can ensure the dust-proof and waterproof environment required for the operation of the transformer 721, and prevent the large amount of heat and noise generated by the transformer 721 during operation from interfering with other equipment. The ventilation device 9 is used to ventilate and dissipate heat for the transformer room 72 to ensure the moisture-proof and ventilation environment required during operation. Optionally, the ventilation device 9 uses a fan and a ventilation pipe, and the air permeable portion 10 provided on the side wall 3 adjacent to the transformer chamber 72 is used to connect to the ventilation pipe, and the air permeable portion 10 realizes ventilation and heat dissipation. An inspection port is provided at the bottom of the equipment cabin for inspecting the cables and busbars in the cable channel 5, and a cover plate can be provided on the inspection port. Both the high-pressure chamber 6 and the low-pressure chamber 7 have multiple side walls 3, and at least one sealed hatch 8 is provided on the side wall 3. The transformer chamber 72 is also provided with an inspection port for convenient cable inspection.

[0025] In actual application, one or more high-voltage outlet terminals 62 can be set according to the on-site conditions to supply power to one or more high-voltage devices, and the number of connectors of the high-voltage outlet terminals 62 is not limited and can be adjusted according to actual conditions. There can be multiple high-voltage outlet terminals 62, so the high-voltage chamber 6 is also correspondingly provided with multiple high-voltage outlet cabinets 64 connected to the multiple high-voltage outlet terminals 62 to supply power to multiple external high-voltage devices. For example, the embodiment in the figure is provided with two high-voltage outlet terminals 62, and the high-voltage chamber 6 is also correspondingly provided with two high-voltage outlet cabinets 64 connected to the two high-voltage outlet terminals 62.

[0026] The box-type substation according to the embodiment of the present invention has the advantages of good safety and convenient maintenance.

[0027] In some embodiments, the transformer chamber 72 has a transformer chamber 72 door and a sealed cabin door 8. A trip switch is provided on the transformer chamber 72 door. The trip switch is connected to the high-voltage incoming line switch of the transformer 721 in the transformer chamber 72 to control the operation of the transformer 721. The sealed cabin door 8 is located on the side wall 3 adjacent to the transformer chamber 72, and a ventilation portion 10 is provided on the sealed cabin door 8.

[0028] Specifically, the door of the transformer room 72 is linked to the tripping switch. When the door of the transformer room 72 is opened, the tripping switch cuts off the high-voltage incoming line switch to prevent the input of high-voltage electricity, thereby ensuring the safety of personnel and substation equipment. Optionally, the door of the transformer room 72 can be an electromagnetic lock, which has high safety and can be easily opened in an emergency, thereby ensuring the safety of the operator. The transformer 721 converts high-voltage electricity into low-voltage electricity through the low-voltage inlet and outlet cabinet 722 transformer room door; 73 outputs low-voltage electricity through the distribution box 74 to supply power to external low-voltage equipment. The form of the vent 10 is not limited, and it can be a louver vent or a porous vent, as long as the internal space can be ventilated and heat dissipated with the outside. The door frame of the sealed door 8 can be sealed by a sealing strip. The sealing design of the sealed door 8 can isolate the internal space from the outside, thereby preventing external water and dust from entering the internal space and damaging the substation equipment placed in the internal space, so as to ensure the normal operation of the substation and extend the service life of the substation equipment.

[0029] In some embodiments, the front sides of the cabinets of the high-voltage power distribution equipment and the low-voltage power distribution equipment for maintenance and operation by operators are all facing the sealed hatch 8, so the operators do not need to enter the substation, and can open the sealed hatch 8 to maintain and repair the corresponding power distribution equipment and the inlet and outlet terminals. Optionally, according to actual needs and the purpose of saving, only part of the power distribution equipment is equipped with a corresponding sealed hatch 8.

[0030] In some embodiments, the box-type substation also includes a monitoring mechanism, which includes multiple smoke sensors 11 and a constant temperature and humidity device 12. The smoke sensors 11 are located in the low-voltage chamber 7, the high-voltage chamber 6 and the transformer chamber 72 for detecting smoke, and the constant temperature and humidity device 12 is respectively located in the low-voltage chamber 7 and the high-voltage chamber 6 for regulating temperature and humidity.

[0031] Specifically, smoke sensors 11 are provided in the low-pressure chamber 7, the high-pressure chamber 6, and the transformer chamber 72 to monitor the indoor smoke concentration and temperature in real time to prevent fire hazards. The constant temperature and humidity device 12 can be, but is not limited to, air-conditioning equipment to adjust the required temperature and humidity in the low-pressure chamber 7 and the high-pressure chamber 6 respectively. The side wall 3, the partition wall 4, and the transformer chamber 72 are made of flame-retardant and heat-insulating materials, which can be double-layer steel plates, which can be flame-proof, heat-insulating, waterproof, and dust-proof, and meet the explosion-proof protection level IP54.

[0032] In some embodiments, a rod-type door lock is provided on the sealed cabin door 8, and the rod-type door lock includes a locking rod 81 and a handle 82. The handle 82 connects the locking rod 81 to the sealed cabin door 8, and both ends of the locking rod 81 respectively pass over the sealed cabin door 8 and are connected to the side wall 3 or the base 2.

[0033] Specifically, the locking rod 81 is fixedly connected to the sealed cabin door 8, the upper end of the locking rod 81 is locked at the upper side wall 3 of the sealed cabin door 8, and the lower end of the locking rod 81 is locked at the lower side wall 3 or the base 2 of the sealed cabin door 8. The rod-type door lock locks the sealed cabin door 8 from the upper and lower sides of the sealed cabin door 8, thereby enhancing the sealing performance of the sealed cabin door 8 and preventing the sealed cabin door 8 from being opened by mistake due to collision when the substation is moved. When it is necessary to open, the upper and lower ends of the locking rod 81 can be unlocked, and the handle 82 can be unlocked from the sealed cabin door 8, and the sealed cabin door 8 can be opened by pulling the handle 82.

[0034] In some embodiments, a sliding portion 21 is disposed on the base 2 , and the sliding portion 21 includes a pulley or a slide plate 211 equipped with a slide bar 212 . The slide bar 212 extends along the length direction of the base 2 to support the base 2 .

[0035] Specifically, the sliding part 21 can be a slide plate 211 having slide bars 212, and the slide bars 212 can evenly distribute the weight of the substation to each slide bar 212, providing better support for the bottom plate. The slide plate 211 can contact the ground when the substation moves, reducing the friction with the ground, thereby facilitating the movement of the substation.

[0036] Furthermore, both ends of the slide bar 212 are streamlined curved surfaces, which can reduce the static friction between the substation and the ground when the substation starts to move, thereby making it easier to move the substation.

[0037] The slide plate 211 is suitable for sliding on a flat ground, and is also suitable for sliding on an uneven ground in the wild, such as an open-pit mine. The slide bar 212 is made of a smooth material. When the substation is moved, the slide bar 212 contacts the ground, reducing the contact area between the base 2 and the ground. The smooth slide bar 212 can make it easier for the substation to slide relative to the ground. When the sliding part 21 is a roller, the base 2 moves with the movement of the roller.

[0038] In some embodiments, a door access sensor 83 is provided on the sealed door 8 , and the door access sensor 83 is used to detect the opening and closing of the sealed door 8 .

[0039] Specifically, the access control sensor 83 can be used to detect the opening and closing of the sealed door 8, and timely control the power on and off to ensure the safety of the operator. Optionally, the access control sensor 83 can also be associated with the lighting provided in the high-pressure chamber 6 and the low-pressure chamber 7, and the opening of the sealed door 8 can turn on the lighting.

[0040] In some embodiments, the box-type substation further includes a traction ring 13 and a protrusion 14. The traction ring 13 is located on the base 2 or the side wall 3 for traction and movement, and the protrusion 14 is located on the base 2 for winding or fixing the traction rope.

[0041] Specifically, the traction ring 13 may be hung with a hook or tied with a traction rope. When the substation is moved, the hook or traction rope drives the substation to move through the traction ring 13. The traction ring 13 may also be set at the side wall 3, as long as the substation can be moved by traction thereof.

[0042] The raised portion 14 can be used to wind a traction rope or fix other traction ropes, so as to assist in pulling the substation to move. The raised portion 14 can be circular in shape, which is convenient for winding and fixing the traction rope, or can be polygonal, elliptical, nail-shaped, etc., as long as the traction rope can be wound, the other side of the base 2 can be used to wind and fix the traction rope, so that when moving the substation, the substation can be pulled from all angles to move to the required position, and the direction of the substation setting can be adjusted conveniently.

[0043] In some embodiments, the top cover 1 is a pointed top cover 1 with a slope, an outer eave 101 is arranged at the bottom of the top cover 1 for drainage, a plurality of drainage holes are distributed at the bottom of the outer eave 101 , and a lifting ring 102 is arranged on the top cover 1 .

[0044] Specifically, the top cover 1 is of a pointed slope type, and the cross section of the top cover 1 is approximately triangular. The pointed slope type top cover 1 can prevent water from accumulating on the top cover 1 of the substation and leaking into the internal space of the substation to affect the operation of the internal substation equipment. Substations are usually set up outdoors. When it rains, rainwater can roll down along the pointed slope and be discharged from the outer eaves 101. Drain holes are distributed at the lower end of the outer eaves 101 to accelerate drainage, and the accumulated water on the top cover 1 can be discharged from the drainage holes. A lifting ring 102 is set on the top cover 1 for easy lifting. The lifting ring 102 can also be hung with a hook or tied with a rope. When moving the substation, the substation can be lifted and moved by a hook or a traction rope through the lifting ring 102.

[0045] In some embodiments, a cable box 15 is respectively provided on both sides of the high-voltage chamber 6 and the low-voltage chamber 7. The interface end of the cable box 15 is used to introduce an external cable and connect it to the high-voltage input terminal 61, the high-voltage output terminal 62 or the low-voltage output terminal 71, and a sealing ring is provided at the interface end.

[0046] Specifically, the cable box 15 is provided with a cable interface end, which is used to introduce the external cable from the bottom. The cable box 15 can guide the path of the external cable, shorten the hanging length of the external cable, and prevent the weight of the external cable from being applied to the high-voltage input terminal 61 and the high-voltage output terminal 62 on the high-voltage side or the low-voltage output terminal 71 on the low-voltage side, causing damage to the high-voltage input terminal 61, the high-voltage output terminal 62 and the low-voltage output terminal 71. At the same time, it also prevents the external cable from being directly disconnected from the high-voltage input terminal 61, the high-voltage output terminal 62 and the low-voltage output terminal 71 when the external cable is pulled by external force. The sealing ring can prevent external dust, debris, etc. from entering the internal space of the substation.

[0047] The cable box 15 may also be provided with a panel. When installing the cable, the cable interface end can be exposed by opening the panel, making it more convenient to introduce the cable. After the cable installation is completed, closing the panel can further prevent external dust, debris, etc. from entering the cable interface end.

[0048] In some embodiments, the low-pressure chamber 7 and the high-pressure chamber 6 are respectively provided with inspection doors 16 for personnel to enter and exit.

[0049] Specifically, operators can enter the inner space of the substation through the inspection door 16 to perform wiring, inspection, and equipment operation.
