Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a fire transformer fixing structure. Furthermore, this utility model also relates to a drawer switch cabinet including the aforementioned fire transformer fixing structure. Background Technology

[0002] Electrical fire hazards are often hidden and difficult to detect, and non-professionals cannot properly inspect electrical equipment for overheating, insulation aging, or damage. Therefore, we need to take targeted preventative measures, such as installing fire transformers on current-carrying lines to detect short circuits, leakage, and other issues in advance. When a problem occurs, staff can receive information and intervene before a fire breaks out, thus preventing electrical fires.

[0003] Drawer-type switchgear boasts high reliability, safety, and interchangeability, making it a relatively advanced type of switchgear. As a centralized power distribution center, it is suitable for industrial and mining enterprises and high-rise buildings requiring high power supply reliability. When drawer-type switchgear supplies power to residential areas or special regions, fire transformers are often required to prevent electrical fires. However, since drawer-type switchgear technology was developed and installed relatively early, it did not have pre-designed installation locations for fire transformers. When additional installation is needed, a crossbeam must be temporarily added behind the drawer for the fire transformer. Due to the special electrical characteristics of fire transformers, which require three phases and four wires to pass through simultaneously, when installing with a horizontal crossbeam, the outgoing cables must pass upwards from the bottom of the drawer cabinet through the transformer and connect to the drawer contacts for phase connections. The neutral wire then bends downwards back to the bottom of the cabinet to connect to the neutral busbar. This results in long cable stripping lengths, messy wiring, and wasted materials. When encountering cables that are difficult to bend through the fire transformer, the fire transformer must be removed, passed through the cable, and then re-fixed. This not only affects cable connection construction but also causes inconvenience for future maintenance.

[0004] In conclusion, how to improve the construction efficiency of fire transformer installation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a fire transformer fixing structure that makes construction more convenient and wiring neater when cable connection work is carried out after the fire transformer is installed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this utility model is to provide a fire transformer fixing structure that makes construction more convenient and wiring neater when connecting cables after the fire transformer is installed. It not only saves time and materials, but also facilitates maintenance and repair.

[0033] Another core aspect of this utility model is to provide a drawer switch cabinet that includes the aforementioned fire transformer fixing structure.

[0034] Please refer to Figure 1 A fire transformer fixing structure for a drawer switch cabinet includes a connector 1, a fixing member 2, and a fire transformer 3. The connector 1 is installed in the drawer switch cabinet. The fixing member 2 and the connector 1 are detachably connected by a disassembly member 4. The fire transformer 3 is installed on the fixing member 2.

[0035] It should be noted that, in the embodiments of this utility model

[0036] Optionally, in some embodiments, both the connector 1 and the fixing member 2 are rod-shaped structures, which helps to reduce the overall area and weight occupied by the fixing structure, making it convenient to carry and install.

[0037] Optionally, in some embodiments, the connector 1 and the fastener 2 are detachable by means of bolts or snaps.

[0038] Optionally, in some embodiments, the connector 1 may be fixed inside the drawer switch cabinet by means of bolts or welding.

[0039] Optionally, in some embodiments, the fire transformer 3 can be detachably mounted to the fixing member 2 by bolts.

[0040] When multiple fire transformers 3 are installed in the same switch drawer cabinet, several sets of fixing structures can be set up, and these sets of fixing structures can be staggered to further improve the utilization of the internal space of the cabinet and meet the installation requirements of a large number of fire transformers 3.

[0041] In use, the fixed structure is installed in the drawer switch cabinet. The fixed structure includes connector 1, fixing component 2, and fire transformer 3. The fire transformer 3 is used to detect the current of the line in real time and provide detection feedback. Connector 1 is installed in the drawer switch cabinet. Fixing component 2 and connector 1 are detachably connected by disassembly component 4. The fire transformer 3 is installed on fixing component 2. That is to say, by connecting the fire transformer 3 to fixing component 2 and connector 1, the fire transformer 3 can be installed inside the drawer switch cabinet, thereby realizing the installation of the fire transformer 3. At the same time, it is convenient for construction personnel to disassemble the transformer when necessary, which greatly improves construction efficiency, facilitates inspection and maintenance, and ensures the safe operation of the electrical system.

[0042] Please refer to Figure 4 In some embodiments, the disassembly component 4 is installed on the connector 1, and the connector 1 is provided with a connecting groove 101. When the disassembly component 4 enters the connecting groove 101, the fixing component 2 is connected to the connector 1. That is, the disassembly component 4 enables the connector 1 and the fixing component 2 to be disassembled and connected, so as to facilitate the user to disassemble the fire transformer 3 and improve the efficiency of wiring.

[0043] Please refer to Figure 3 In some embodiments, the disassembly member 4 includes a disassembly part 401, which has a structure whose width increases along the direction close to the connector 1. The cross-section of the connecting groove 101 is C-shaped, and the minimum width of the connecting groove 101 is less than the maximum width of the disassembly part 401. The side of the connecting groove 101 is provided with an opening 102 for the disassembly part 401 to enter the connecting groove 101. Specifically, the disassembly part 401 has a structure with different widths, and the width increases along the direction close to the connector 1. Therefore, when the disassembly part 401 enters the connecting groove 101, the disassembly part 401 is blocked by the connecting groove 101, thereby fixing the fastener 2 and the connector 1, and also enabling the fast disassembly of the fastener 2 and the connector 1.

[0044] Optionally, in some embodiments, the disassembly part 401 is a plate-shaped T-shaped structure, that is, the T-shaped structure realizes the functions of fixing and disassembling the disassembly part 4.

[0045] In other embodiments, the disassembly part 401 is a spherical or hemispherical structure, which, when it enters the connecting groove 101, enables the installation and fixation of the fastener 2 and the connector 1.

[0046] In other embodiments, the disassembly part 401 has an inverted trapezoidal structure, and the smaller end of the trapezoid is connected to the fixing member 2. When it enters the connecting groove 101, the fixing member 2 and the connecting member 1 are installed and fixed.

[0047] In other embodiments, the disassembly part 401 has a triangular structure, and one corner of the triangle is connected to the fixing member 2. When it enters the connecting groove 101, the fixing member 2 and the connecting member 1 are installed and fixed.

[0048] Optionally, in some embodiments, the connecting groove 101 extends through the length of the connector 1. Increasing the length of the connecting groove 101 allows the disassembly part 401 to slide freely within the connecting groove 101, thereby conveniently changing its position and further satisfying the purpose of adjusting the position of the fire transformer 3.

[0049] Please refer to Figure 4 In some embodiments, the fixing member 2 includes a fixing part 201 and a connecting part 203. The fixing part 201 is perpendicular to the connecting part 203. The connecting part 203 is used to connect with the connecting member 1. The fire transformer 3 is installed on the fixing part 201. That is, the fixing member 2 has an L-shaped or T-shaped structure, so that the fixing part 201 extends a preset distance away from the drawer switch cabinet, which further facilitates the installation of the fire transformer 3.

[0050] Optionally, in some embodiments, the fixing part 201 and the connecting part 203 can be fixed by welding, and an inclined reinforcing rib is provided between the fixing part 201 and the connecting part 203.

[0051] In other embodiments, the connecting part 203 is provided with threaded holes and distributed along the length direction of the connecting part 203. The fixing part 201 is installed on the connecting part 203 by bolts. When several fire transformers 3 need to be installed inside the same drawer switch cabinet, the position of the fire transformers 3 can be adjusted by installing the fixing part 201 in different threaded holes, so as to meet the adjustment of the spacing between several fire transformers 3.

[0052] In other embodiments, the connecting part 203 is provided with a sliding groove, and the fixing part 201 is provided with a sliding protrusion corresponding to the sliding groove. The sliding protrusion slides in the sliding groove. At the same time, at least one bolt perpendicular to the sliding groove is threaded on the fixing part 201. By turning the bolt, when the bolt is disengaged from the connecting part 203, the fixing part 201 can slide freely on the connecting part 203. When the bolt head contacts the connecting part 203, the relative position of the fixing part 201 and the connecting part 203 can be fixed by their friction, thus meeting the requirement of rapid position adjustment of the fire transformer 3.

[0053] Please refer to Figure 4 In some embodiments, the fixing part 201 is provided with a mounting hole 202, and the fire transformer 3 is mounted on the fixing member 2 through the mounting hole 202. That is to say, the fire transformer 3 can be mounted on the fixing member 2 through the mounting hole 202 on the fixing part 201.

[0054] In the above embodiment, the fire transformer 3 is provided with a hook, which can be used to install the fire transformer 3 on the fixing member 2 and also to quickly disassemble the fire transformer 3, facilitating the rapid wiring of the fire transformer 3.

[0055] Optionally, in some embodiments, the fire transformer 3 is provided with a mounting plate and a through hole, and the fire transformer 3 can be fixed to the fixing member 2 by bolts through the mounting plate.

[0056] Optionally, in some embodiments, the mounting hole 202 is a strip-shaped hole, and the mounting hole 202 is arranged along the length direction of the fixing part 201. That is to say, the fire transformer 3 can be quickly adjusted in its installation position through the strip-shaped hole.

[0057] In other embodiments, the mounting hole 202 is a strip-shaped hole, and the mounting hole 202 is arranged along the width direction of the fixing part 201. That is to say, the relative position of two adjacent fire transformers 3 can be adjusted through the strip-shaped hole, so that the two adjacent fire transformers 3 are staggered, further meeting the installation requirements when a large number of fire transformers 3 are installed in the same switch drawer cabinet.

[0058] A drawer switch cabinet includes any of the above-mentioned fire transformer fixing structures.

[0059] Please refer to Figure 1 In some embodiments, a crossbeam 5 is also included. The crossbeam 5 is installed inside the drawer switch cabinet. The connector 1 is perpendicular to the crossbeam 5 and is installed on the crossbeam 5. That is, by setting the crossbeam 5 inside the drawer switch cabinet and fixing the connector 1 to the crossbeam 5, the fire transformer 3 can be installed inside the drawer switch cabinet.

[0060] Alternatively, in some embodiments, the crossbeam 5 is installed inside the drawer switch cabinet by welding or bolts.

[0061] Optionally, in some embodiments, the crossbeam 5 is provided with a plurality of mounting holes 202 arranged along its length. The connector 1 is fixed to the crossbeam 5 by bolts cooperating with the mounting holes 202. At the same time, the position can be adjusted by changing different mounting holes 202 to meet the lateral adjustment of the installation position of the fire transformer 3. Furthermore, when multiple fire transformers 3 are installed in the same drawer switch cabinet, the multiple fire transformers 3 can be staggered by adjusting the lateral position of the connector 1.

[0062] In other words, the key point of this utility model is: to install a fixed structure in a drawer switch cabinet. The fixed structure includes a connector 1, a fixing member 2, and a fire transformer 3. The fire transformer 3 is used to detect the current of the line in real time and provide detection feedback.

The fire transformer 3 is installed on the fixing member 2. That is to say, by connecting the fire transformer 3 to the fixing member 2 and the connector 1, the fire transformer 3 can be installed inside the drawer switch cabinet, thereby realizing the installation of the fire transformer 3. At the same time, it is convenient for construction personnel to disassemble the transformer when necessary, which greatly improves construction efficiency, facilitates inspection and maintenance, and ensures the safe operation of the electrical system.
