Description

Technical Field

[0001] The present invention relates to a temperature rise monitoring device for a busbar trunking unit in a data center, belonging to the technical field of busbar trunking monitoring. Background Art

[0002] With the rapid development of the Internet industry, the market scale of data centers shows an increasing trend. Compared with the traditional power distribution mode, the data center busbar adopts a modular structure, mainly including a starting box, a busbar joint connector, a busbar trunking body, a plug-in box, a support member, and an end box, etc. It eliminates the line head cabinet and cables, improves the utilization rate of equipment, and greatly reduces the power loss. The unit body of the busbar trunking system and the power take-off connection of the plug-in box have full-point pluggability. The plug-in box can be customized as needed. When the position or capacity of the load changes, it can be replaced online. Since the busbars are distributed on both sides of the shell of the data center busbar trunking unit body, the plug-in structure needs to be inserted from the bottom of the busbar trunking and then rotated so that the plug pins contact the busbars to take power. The abnormal temperature rise of the plug-in part affects the current-carrying capacity, voltage drop, safety, and the service life of the busbar trunking. The temperature rise monitoring devices in the prior art adopt a method similar to that of a USB device, directly inserted into the busbar joint part in a hot-pluggable manner, and only applicable to the joint part by contacting the busbar copper bar, which is difficult to meet the sensitive demand for temperature monitoring of the plug-in part of the busbar unit body. Summary of the Invention

[0003] The purpose of the present invention is to address the deficiencies of the prior art and provide a temperature rise monitoring device for a busbar trunking unit in a data center, which has a compact structure and can be detachably installed. When the moving contact rotates and plugs into any end of the data center busbar trunking monomer, it takes power by elastic pressing and supporting with a spring piece, and wirelessly remotely transmits through the resistance sensing of a temperature sensor, and realizes real-time display monitoring and alarm to monitor the temperature rise of the busbar trunking unit body in the data center, improving the operating reliability, safety, and service life of the busbar system.

[0004] The present invention is realized by the following technical solutions:

[0005] A temperature rise monitoring device for a busbar trunking unit in a data center includes two mirror-image-matching shells, a group of moving contacts located on both sides of the shells, and grounding terminals located at the ends of the shells. First notches and second notches corresponding to the moving contacts are provided on both sides of the shells. The outside of the moving contacts protrudes from the shells. One end of the inner side of the moving contacts is provided with a contact seat that is slidably and limit-fitted with the shells. The other end of the inner side of the moving contacts is provided with a third notch for the contact seat of the adjacent moving contact to give way. A copper nose is connected to the contact seat.

[0006] A support plate located inside the moving contacts is provided in the shell. A spring piece is provided between the support plate and the moving contacts. A temperature sensor resistor passing through the moving contacts is connected between the spring piece and the support plate. A wire passing hole is provided at the tail of the shell.

[0007] On both sides of the shell, there are matching fourth notches and first bosses. Inside the two sides of the shell, there are second bosses. On the two second bosses, there are matching threaded counterbores and first through holes. At the tail of the shell, there is a first limiting plate, and at least one mounting hole corresponding to the second boss is provided on the first limiting plate;

[0008] The moving contact is in a frame shape and the outer side is bent into a U-shaped structure. On the outer side of the moving contact, there are several fifth notches arranged at intervals and extending to both sides. On the outside of both the first notch and the second notch, there are guard plates that are slidably matched with the outer wall of the moving contact. The support plate is arranged close to the first notch. Inside the shell, there is a hollow sliding table arranged close to the second notch and slidably matched with the bottom of the contact seat. On both sides of the hollow sliding table and both sides of the contact seat, there are second limiting plates with limiting cooperation. On the moving contact, there is a sixth notch arranged close to the third notch. On the shell, there is a third boss arranged close to the second notch and slidably matched with the sixth notch;

[0009] The elastic piece includes a straight segment matched with the inner wall of the outer side of the moving contact, a first wave band and a second wave band connected to both ends of the straight segment. At the end of the first wave band, there is a first abutting plate. On the shell, there is a third limiting plate arranged close to the second notch and in limiting cooperation with the first abutting plate. At the end of the second wave band, there is a second abutting plate connected to the support plate and the temperature sensor resistor;

[0010] The temperature sensor resistor is connected to a PCBA board. On the PCBA board, there is an A / D conversion circuit for converting the resistor voltage division value into a digital signal, an FPGA controller for receiving the A / D conversion circuit and performing logical operations, a wireless transceiver module for receiving and sending the temperature rise data of the FPGA controller. The PCBA board is connected to a power supply for power supply and a digital tube for receiving and displaying the temperature rise data of the FPGA controller;

[0011] The PCBA board is connected to an alarm for receiving the alarm signal of the FPGA controller, including but not limited to audible and visual forms.

[0012] The beneficial effects of the present invention are as follows:

[0013] (1) The two shells are mirror-matched and closed into an integral structure. The moving contact is arranged in the first notch and the second notch corresponding to the cooperation of the two shells. The moving contact is elastically supported by the sliding cooperation of the contact seat with the hollow sliding table of the shell, the sliding cooperation of the sixth notch with the third boss of the shell, the sliding cooperation of the outer wall with the guard plate of the shell, and under the pre-pressure of the internal elastic piece. The first wave band and the second wave band of the elastic piece are pre-pressed and installed under the support of the first abutting plate and the third limiting plate, and the second abutting plate and the support plate respectively. The structure is compact, with few accessories, easy to process and install, and detachable and replaceable;

[0014] (2) After the device is inserted into the busway from the bottom of the data center busway unit, it is clamped inside the U-shaped busbar, and the moving contact presses the compression spring piece. The third notch provides a sliding clearance for the contact seat of the adjacent moving contact. The moving contact reliably contacts the U-shaped busbar under the action of the spring piece's restoring force to draw power and leads out the power distribution through the copper nose on the contact seat.

[0015] (3) The contact ends of the spring piece with the moving contact and the U-shaped busbar sense the temperature to the resistance of the temperature sensor and lead it out to the PCBA board. The temperature rise resistance voltage division value during power distribution at any position of the busway unit is converted into a digital signal through the A / D conversion circuit. The FPGA controller performs logical operations to obtain the temperature rise data and alarm signal and transmits them to the wireless transceiver module for wireless transmission and remote monitoring. The digital tube is used for real-time display monitoring, and the alarm gives an alarm, realizing the temperature rise monitoring of the data center busway unit and improving the operation reliability, safety, and service life of the bus system.

A sixth notch 24 is arranged on the moving contact 2 close to the third notch 7. A third convex platform 25 that is slidably matched with the sixth notch 24 is arranged on the housing 1 and is close to the second notch 5;

[0033] The elastic sheet 10 includes a straight section 101 that is matched with the inner wall of the outer side of the moving contact 2, a first wave band 102 and a second wave band 103 that are connected to both ends of the straight section 101.

[0035] The PCBA board is connected to an alarm for receiving the alarm signal of the FPGA controller, including but not limited to forms of sound and light.

[0036] The working principle of the present invention is as follows:

[0037] Referring to the attached drawings, two housings 1 are in mirror image cooperation to form an integral structure. A grounding terminal 3 is arranged in one housing 1. The moving contact 2 is arranged in the first notch 4 and the second notch 5 corresponding to the cooperation of the two housings 1. The moving contact 2 is in a frame shape and the outer side is bent into a U-shaped structure, protrudes outside the housing 1, and the inner side is integrally structured with the contact seat 6;

[0038] Part of the moving contact 2 is arranged in the first notch 4 and is limited by sliding cooperation with the outer wall of the guard plate 21. The bottom of the contact seat 6 of the moving contact 2 is in sliding cooperation with the hollow sliding table 22 near the second notch 5, and the moving contact 2 is limited by the second limiting plates 23 on both sides of the hollow sliding table 22 and both sides of the contact seat 6. The contact seat 6 is riveted to the copper nose 8, and the hollow sliding table 22 provides sliding space for the riveting part;

[0039] The elastic piece 10 inside the moving contact 2 is limited by the folded edge 29 of the second bottom plate 28 and the limiting plate. The end of the temperature sensor is limited by the support plate 9. The temperature sensor passes through the second through hole 30 on the second bottom plate 28 of the support plate 9 and the elastic piece 10, and is locked with a nut and fixed to the elastic piece 10 and the temperature sensor through the second through hole 30 of the moving contact 2. When the two shells 1 are closed, the third limiting plate 27 near the second notch 5 cooperates with the first bottom plate 26 to pre-press the elastic piece 10. The folded edge 29 of the first bottom plate 26 is located inside the moving contact 2 and cooperates with both sides of the third limiting plate 27. When the elastic piece 10 acts through the elastic force of the first wave band 102 and the second wave band 103, the straight segment 101 abuts against the inner wall of the outer side of the moving contact 2, realizing the installation of the elastic piece 10 and elastically supporting the moving contact 2 with the elastic piece 10;

[0040] When the two shells 1 are closed, the fourth notches 13 at both edges cooperate with the first bosses 14 to strengthen the closed sealing performance after closing and quickly align. The guard plates 21 outside the first notch 4 and the second notch 5 of the two shells 1 are closed and are in sliding cooperation with the outer wall of the moving contact 2. The sixth notch 24 on the moving contact 2 near the third notch 7 is in sliding limiting cooperation with the third boss 25 on the shell 1 near the second notch 5 to ensure the positioning and installation of the moving contact 2. The two shells 1 are closed and installed by bolts passing through the first through holes 17 and being in threaded cooperation with the threaded counter bores 16, realizing the detachable installation of the group of moving contacts 2 on both sides on the shell 1;

[0041] The leads of the copper nose 8 and the grounding terminal 3 are led out from the closed wiring holes 12 for busbar distribution. The lead of the temperature sensor resistor 11 is led out from the wiring holes 12 for electrical connection with the PCBA board for temperature rise monitoring. The wireless transceiver module is used to connect with the terminal of the bus monitoring system through wireless transmission and transmit monitoring in real time; By mirroring and cooperating the two shells 1 to set the group of moving contacts 2 on both sides, the structure is compact, with few accessories and is easy to process, install, detach and replace;

[0042] After the device is inserted into the busbar from the bottom of a single data center busbar unit, the whole is rotated so that the outer side of the moving contact 2 in a U shape is inserted into the inwardly bent U-shaped busbar on the inner side for clamping. The U-shaped busbar presses the moving contact 2, causing the moving contact 2 to press the elastic piece 10. The moving contact 2 stably slides into the housing 1 under the sliding fit between the contact seat 6 and the hollow slide 22, the sliding fit between the sixth notch 24 and the third boss 25, and the sliding fit between the outer wall and the guard plate 21. The third notch 7 provides a sliding clearance for the contact seat 6 of the adjacent moving contact 2.

[0043] The first wave band 102 and the second wave band 103 of the elastic piece 10 are respectively compressed under the support of the first bottom plate 26 and the third limiting plate 27, and the second bottom plate 28 and the support plate 9. The straight section 101 and the U-shaped busbar are pressed against both sides of the moving contact 2, enabling the moving contact 2 to reliably contact and draw power from the U-shaped busbar under the restoring force of the elastic piece 10, and leading out power distribution through the copper nose 8 on the contact seat 6. The fifth notch 20 facilitates the machining of the U-shaped part and ensures the contact area with the busbar. The grounding terminal 3 contacts the busbar housing 1 for grounding. The first limiting plate 18 is in a limiting fit with the busbar unit housing 1 as it rotates. The mounting hole 19 is used to connect to the plug-in box. A PCBA board and a power supply are arranged in the plug-in box, and a digital tube and an alarm are arranged on the plug-in box.

[0044] The contact ends of the elastic piece 10 with the moving contact 2 and the U-shaped busbar sense the temperature to the temperature sensor resistor 11 and lead it out to the PCBA board, enabling the temperature rise during power distribution at any position of the busbar unit to be reflected by the temperature sensor resistor 11 as different resistance value changes and voltage division values at different temperatures, which are converted into digital signals recognizable by the FPGA controller through an A / D conversion circuit. The FPGA controller performs logical operations based on the digital signals to obtain temperature rise data and alarm signals above the threshold, and transmits them to the wireless transceiver module JF24D for wireless remote monitoring, transmits them to the digital tube for real-time display monitoring, and transmits the abnormal temperature rise alarm signals to an alarm in forms including but not limited to sound and light for warning, realizing the temperature rise monitoring of the data center busbar unit and improving the operation reliability, safety, and service life of the busbar system.
