Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a spliced ​​multifunctional power distribution cabinet. Background Art

[0002] Traditional power distribution cabinets are usually divided into two types: power supply cabinets and frequency conversion cabinets, which are used to provide stable power output and realize frequency conversion speed regulation functions respectively.

[0003] In actual applications, these two types of distribution cabinets often need to be installed separately, which not only takes up a large space, but also has complex wiring and difficult maintenance. In addition, when the distribution system needs to be upgraded or expanded, it is often necessary to redesign and install new distribution cabinets, which increases costs and time investment. Utility Model Content

[0004] The problem to be solved by the present application is that the existing power distribution cabinets have relatively single functions and can only be configured and used independently, and cannot be flexibly combined and spliced, which not only occupies a large space but also increases the cost of additional configuration.

[0005] In order to solve the above-mentioned technical problems, the present application provides a spliced ​​multifunctional power distribution cabinet, including a power cabinet for distributing electric energy and switching power supplies, and a frequency conversion cabinet for adjusting the operating frequency of equipment and smoothly starting the equipment. The power cabinet and the frequency conversion cabinet are arranged side by side in a regular manner and are interconnected.

[0006] Since the power distribution cabinet of the present application is designed with a power supply cabinet and a frequency conversion cabinet, it is possible to implement emergency switching operations of the power supply through the power supply cabinet, and to implement frequency conversion adjustment operations of current and voltage through the frequency conversion cabinet, thereby solving the problem that the power distribution cabinets in the prior art have relatively single functions and can only be configured and used independently, and cannot be flexibly combined and spliced, thereby not only occupying a large space, but also increasing the cost of additional configuration.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0014] The present application relates to a splicing type multifunctional power distribution cabinet, such as Figure 1-5 As shown, the power distribution cabinet includes a power cabinet 1 for distributing electric energy and switching power supplies, and a frequency conversion cabinet 2 for adjusting the operating frequency of the equipment and smoothly starting the equipment. The power cabinet 1 and the frequency conversion cabinet 2 are arranged side by side in a regular manner and are interconnected, so that the power cabinet 1 is used to stably transmit electric energy, and the frequency conversion cabinet 2 is used to output the electric energy from the power cabinet 1 after frequency conversion.

[0015] The power supply cabinet 1 includes a first cabinet body 3, a first cabinet door 4, a first cabinet seat 5, a power switch 9 and a first shunt switch 11. The first cabinet body 3 is a rectangular parallelepiped structure and is arranged vertically. The first cabinet door 4 that can be rotated and opened is arranged in front of the first cabinet body 3. The first cabinet seat 5 for supporting and ventilating is arranged at the bottom of the first cabinet body 3. The top surface of the first cabinet seat 5 is evenly provided with ventilation slots 15, and the side of the first cabinet seat 5 is evenly provided with ventilation through holes 16. The first cabinet body 3 is arranged inside with a power switch 9 for realizing the power on and off function. In order to avoid the power supply being disconnected due to some reasons, In order to prevent power outages caused by power failures and the power outage losses caused by the inability to restore power supply in a short time, the power switch 9 uses a dual power switch 9 with a power switching function, and a first branch switch 11 is arranged inside the first cabinet 3 to prevent overload or short circuit that may easily cause a fire, thereby realizing the on and off of the transmission line. The number of first branch switches 11 can be configured as one or more according to actual practical needs. When the number of first branch switches 11 configured is multiple, the idle and unused first branch switches 11 can be used as standby switches for standby replacement in the event of a line failure.

[0016] The frequency conversion cabinet 2 includes a second cabinet body 6, a second cabinet door 7, a second cabinet seat 8, a second shunt switch 13, a frequency converter 14, and a gear knob. The second cabinet body 6 is a rectangular parallelepiped structure and is arranged side by side on one side of the first cabinet body 3. A second cabinet door 7 that can be rotated and opened is arranged in front of the second cabinet body 6. A second cabinet seat 8 for supporting and ventilating is arranged at the bottom of the second cabinet body 6. The top surface of the second cabinet seat 8 is evenly provided with ventilation slots 15, and the side surface of the second cabinet seat 8 is evenly provided with ventilation through holes 16. The interior of the second cabinet body 6 is arranged with a current changing mechanism. The frequency and voltage converter 14 is connected to the power switch 9 through the terminal block 10. In order to prevent the frequency converter cabinet 2 from short-circuiting or overloading during operation, a second branch switch 13 with short-circuit and overload protection is connected in series to the upper part of the terminal block 10 between the frequency converter 14 and the power switch 9. The frequency converter 14 has a gear knob that can adjust multiple frequency conversion gears, so that the current and voltage can be properly adjusted according to actual practical needs. The frequency converter 14 is connected to the external power supply equipment through the terminal block 10.

[0017] A plurality of ammeters for monitoring current changes in each circuit and a voltmeter for monitoring line voltage changes are arranged inside the first cabinet 3 and the second cabinet 6 respectively.

[0018] Since the power switch 9, the inverter 14 and the branch switch all need to be connected by a terminal block 10, in order to ensure that the terminal block 10 can be stably arranged inside the first cabinet 3 and the second cabinet 6 and avoid leakage, the terminal block 10 is connected to the inner walls of the first cabinet 3 and the second cabinet 6 respectively through insulators 12.

[0019] When in use, firstly, the main power supply and the backup power supply are selected according to the actual situation through the power switch 9 in the power supply cabinet 1, and then the overload and short-circuit protection operation of the branch is realized through the configured multiple first branch switches 11, and then the overload or short-circuit protection operation of the frequency converter 14 can be performed through the second branch switch 13 in the frequency converter cabinet 2, and the frequency converter 14 adjusts the current and voltage of the electric energy transmitted by the power switch 9 through the terminal block 10, so that the current and voltage meet the needs of the electrical equipment, and when the power supply cabinet 1 and the frequency converter cabinet 2 are in operation, they can also use the through slots and through holes 16 of the first cabinet seat 5 and the second cabinet seat 8 to perform effective air cooling and heat dissipation operations, so that the power switch 9 and the frequency converter 14 can perform stable operation.
