Description

Technical Field

[0001] The utility model relates to the technical field of electric switch cabinets, in particular to a switch cabinet busbar mechanism. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches and various AC contactors.

[0003] In the prior art, the busbars in the switch cabinet are all made of solid copper or aluminum as busbars and branch busbars. Due to the skin effect during current transmission, the current usually only accumulates on the surface of the wire, and the overcurrent inside the solid wire is very small, resulting in low current carrying efficiency per unit material in the switch cabinet busbar, consuming materials and generating high heat. In particular, the high-current busbar has a high temperature rise during operation, which creates a common safety hazard.

[0004] Based on the above reasons, the utility model designs a busbar mechanism for a switch cabinet. By using hollow copper tubes or aluminum tubes as busbars, it not only ensures the normal passage of current, but also saves more materials. It is also convenient for ventilation, provides safe and reliable protection for the wiring of the switch cabinet, saves installation space, and is convenient for later maintenance and inspection. Summary of the invention

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a switch cabinet busbar mechanism, which uses copper or aluminum tubular materials as conductors to achieve a better current skin effect and improve the conductivity efficiency of the material per unit weight. At the same time, the operating temperature of the busbar is controlled by temperature control and the action of a fan to ensure safe operation of the equipment.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a switch cabinet busbar mechanism, including a plurality of row switch cabinets, a busbar, and a busbar branch. The busbar passes through the switch cabinets and leads out the busbar branches in a plurality of the switch cabinets. It also includes a fan, a temperature controller, a circuit breaker and a temperature sensor. The busbar and the busbar branch are hollow tubular metal conductors and are interconnected.

[0007] Several temperature sensors are installed on the busbar and branch busbars.

[0008] A temperature controller for detecting the temperature of a temperature sensor is arranged on the outer wall of the switch cabinet.

[0009] The temperature controller is electrically connected to the fan.

[0010] The end of the busbar is connected to a fan for exhausting air through an insulating pipe.

[0011] Multiple switch cabinets can be arranged side by side.

[0012] Compared with the prior art, the utility model uses copper or aluminum materials as hollow pipes as conductors, which not only ensures the current carrying capacity of the conductor, but also saves more materials, facilitates ventilation and cooling, and provides safe and reliable protection for the wiring of the switch cabinet.

[0015] 1 is the switch cabinet, 2 is the busbar, 3 is the busbar branch, 4 is the fan, 5 is the temperature controller, 6 is the circuit breaker, and 7 is the temperature sensor. DETAILED DESCRIPTION

[0016] The utility model is now further described with reference to the accompanying drawings.

[0017] See also Figure 1 The utility model provides a switch cabinet busbar mechanism, including a plurality of row switch cabinets 1, a busbar 2, and a busbar branch 3. The busbar 2 passes through the switch cabinets 1 and leads out the busbar branch 3 in a plurality of the switch cabinets 1. The utility model also includes a fan 4, a temperature controller 5, a circuit breaker 6 and a temperature sensor 7. The busbar branch 3 is provided with a circuit breaker 6. The busbar 2 and the busbar branch 3 are hollow tubular metal conductors and are connected to each other.

[0018] The busbar 2 and the busbar branch 3 are provided with temperature sensors 7 .

[0019] A temperature controller 5 for detecting the temperature of a temperature sensor 7 is arranged on the outer wall of the switch cabinet.

[0020] The temperature controller 5 is electrically connected to the fan 4 .

[0021] The end of the busbar 2 is connected to a fan 4 for exhausting air through an insulating tube.

[0022] A plurality of switch cabinets 1 can be arranged side by side.

[0023] A circuit breaker 6 may also be provided on the busbar branch 3 as selected.

[0024] Working principle:

[0025] See also Figure 1When the utility model is in use, the external busbar 2 passes through the switch cabinets 1 arranged side by side, and the busbar branches 3 can be introduced into several switch cabinets 1. The busbar 2 and the busbar branches 3 are both hollow metal tubular conductors. Due to the skin effect of the current, the current passes through the surface of the metal tube and does not need to pass through the center of the conductor, saving materials. A temperature sensor 7 is provided on each busbar branch 3, and the temperature is transmitted to the temperature controller 5 on the busbar 2. If the temperature is detected to exceed a certain threshold, the temperature controller 5 will start the fan 4, which is insulated and connected to the busbar 2. Since the busbar 2 and the busbar branches 3 are both hollow, the fan 4 can extract the internal hot air to generate air circulation, thereby reducing the temperature of the conductor.

[0026] The above are only preferred implementations of the present invention, which are only used to help understand the method and core ideas of the present application. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the idea of ​​the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0027] The utility model solves the problems of material waste, installation restrictions and high safety risks caused by the use of solid wires in the prior art as a whole. By using hollow copper tubes or aluminum tubes to replace the original conductors and cooperating with fans and temperature control equipment, the material usage is greatly reduced, the conductive efficiency and safety are improved, and subsequent maintenance and inspection are facilitated.
