Description

Technical Field

[0001] This utility model relates to the field of busbar equipment, specifically to a safe and energy-saving sliding rail type busbar. Background Technology

[0002] Busbar trunking is a high-efficiency, safe, and reliable power distribution equipment widely used in industrial, commercial, and civil buildings for power transmission and distribution. Busbar trunking consists of copper or aluminum busbars as the conductive body, covered with insulating material, and protected by a metal shell (such as aluminum alloy or steel). It is usually long and narrow, containing multiple parallel conductors for transmitting three-phase or single-phase power. The structural design of busbar trunking enables it to withstand large currents while maintaining low resistance and temperature rise, ensuring high efficiency and safety of power transmission.

[0003] The existing busbar trunking products require the lower connection cover kit to be installed first, followed by the PE connection busbar, then the upper connection cover kit, then the main connection busbar, and finally the side guard plate. The PE connection busbar contacts the busbar outer shell and then the PE busbar at the top inside the shell, not the copper busbars. In addition, the existing PE connection busbar is shorter than the connection cover kit. After the upper cover kit is installed, it is not possible to check whether the PE connection busbar is installed or to check the tightness of the screws from the outside.

[0004] Existing busbar section connectors cannot measure temperature. More and more projects now require specific connector temperature measurement functions to prevent high contact resistance and overheating between the connector bar and the busbar bar caused by loose screws during installation. Utility Model Content

[0005] This utility model aims to solve the technical problems mentioned in the background section and proposes the following technical solutions:

[0006] A safe and energy-saving sliding rail busbar trunking includes a busbar trunking housing, a housing cover plate, a connector side guard plate, and a temperature measuring device. The top of the busbar trunking housing is provided with a PE connector fixing hole, which is a rectangular hole. A copper pad is provided inside the PE connector fixing hole, and a connection hole is provided on the copper pad. The housing cover plate and the connector side guard plate are respectively installed at both ends and both sides of the busbar trunking housing. The temperature measuring device is installed on the housing cover plate.

[0007] Preferably, both the housing cover and the connector side guard are fixed to the busbar housing by bolts.

[0008] Preferably, the temperature measuring device includes a temperature measuring box, a temperature measuring module, and a temperature measuring wire. The temperature measuring module is located inside the temperature measuring box, and the temperature measuring box is installed on the housing cover plate. The temperature measuring module is provided with a temperature measuring wire socket, and an insulating tube is provided on the connector side guard plate. One end of the temperature measuring wire is inserted into the temperature measuring wire socket, and the other end is inserted into the insulating tube.

[0009] Preferably, a terminal insulation plate is provided at one end of the busbar housing.

[0010] Preferably, one end of the busbar housing is provided with an insulating plate fixing hole.

[0011] The beneficial effects of this utility model are:

[0012] 1. Change the original waist hole at the top of the busbar casing where it is fixed to the PE connection busbar to a rectangular hole, and put a copper pad in the rectangular hole. This way, the PE connection copper busbar can directly contact the copper pad, and it can be installed last, making it easy to check whether the screws are tight.

[0013] 2. By adding a connector temperature measuring device, the temperature between the PE connecting copper busbar and the busbar of the bus trunking can be measured, thereby preventing the problem of high contact resistance and overheating between the PE connecting copper busbar and the busbar of the bus trunking caused by loose screws during the installation of the inter-segment connector.

[0014] 3. By installing terminal insulation plates at the ends of the busbar trunking housing, live conductors can be isolated and leakage paths can be blocked. Furthermore, by setting fixing holes for the insulation plates on the busbar trunking housing, the terminal insulation plates can be installed and fixed with self-tapping screws, which facilitates subsequent inspection and maintenance.

[0023] Example 1

[0024] Reference Figure 1-2 A safe and energy-saving sliding rail busbar trunking includes a busbar trunking housing 1, a housing cover plate 2, a connector side guard plate 3, and a temperature measuring device 4. The top of the busbar trunking housing 1 is provided with a PE connection bar fixing hole 1-1, which is a rectangular hole. A copper pad 5 is provided inside the PE connection bar fixing hole 1-1, and a connection hole 5-1 is provided on the copper pad 5. The housing cover plate 2 and the connector side guard plate 3 are respectively installed at both ends and both sides of the busbar trunking housing 1. The temperature measuring device 4 is installed on the housing cover plate 2.

[0025] Preferably, the housing cover plate 2 and the connector side guard plate 3 are both fixed to the busbar housing 1 by bolts.

[0026] In actual operation, the original waist hole for fixing the PE connection busbar to the top of the busbar shell is changed to a rectangular hole, and a copper pad is placed in the rectangular hole. This allows the PE connection copper busbar to directly contact the copper pad and can be installed last, making it easy to check whether the screws are tight. A temperature measuring device 4 is also added, which can measure the temperature between the PE connection copper busbar and the busbar busbar, thereby preventing the problem of high contact resistance and heat generation between the PE connection copper busbar and the busbar busbar caused by loose screws during the installation of the inter-section connector.

[0027] Example 2

[0028] Reference Figure 1 The temperature measuring device 4 includes a temperature measuring box 4-1, a temperature measuring module 4-2, and a temperature measuring wire 4-3. The temperature measuring module 4-2 is located inside the temperature measuring box 4-1, and the temperature measuring box 4-1 is installed on the housing cover plate 2. The temperature measuring module 4-2 is provided with a temperature measuring wire socket 4-4. An insulating tube 6 is provided on the connector side guard plate 3. One end of the insulating tube 6 is inserted into the bottom of the bolt that fixes the connector side guard plate 3. One end of the temperature measuring wire 4-3 is inserted into the temperature measuring wire socket 4-4, and the other end is inserted into the insulating tube 6. With this structure, when the temperature wire is damaged, it is not necessary to disconnect the power to the busbar trunking; the temperature wire can be directly pulled out and replaced with a new temperature wire.

[0029] Example 3

[0030] Reference Figure 3-4 The difference between this embodiment and embodiment one is that a terminal insulation plate 7 is provided at one end of the bus trunking housing 1. The terminal insulation plate 7 can isolate live conductors and block leakage paths. An insulation plate fixing hole 8 is provided at one end of the bus trunking housing 1. When installing the terminal insulation plate 7, a self-tapping screw can be installed by drilling holes in the terminal insulation plate 7, and then the self-tapping screw can be fixed to the insulation plate fixing hole 8. This is the connection method.
