[0002] With the widespread adoption of information technology and artificial intelligence, data center power supply reliability requirements are becoming increasingly stringent. Minimizing power outages during maintenance requires a switch from a bolted busbar structure to a plug-and-socket design. Due to the plug-and-socket design of power contacts, they can easily overheat during high current operation. Insulator aging can easily occur when cooling and ventilation are poor, potentially leading to power outages. Therefore, it is necessary to monitor power contact temperature and promptly initiate cooling if overheating occurs to prevent power outages. Utility Model Content

DETAILED DESCRIPTION

[0021] It should be noted that, unless there is a conflict, the embodiments in this application and the features described in the embodiments can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship and movement status of the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, in this utility model, the terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0024] Please refer to Figures 1 to 4 The data center main power contact temperature sensor of the embodiment of the present utility model includes a temperature-sensitive liquid container, a temperature-sensitive liquid expansion tube, a transmission mechanism, a reset mechanism, a moving contact assembly, and a static contact assembly.

[0025] The temperature-sensing liquid expansion tube is connected to a temperature-sensing liquid container, which contains the temperature-sensing liquid. This temperature-sensing liquid can be a glycol mixture, and the temperature-sensing liquid container is preferably made of copper. The temperature-sensing liquid expansion tube houses a piston and a piston rod connected to the piston. As the temperature-sensing liquid heats up, it expands, pushing up the piston and driving the piston rod.

[0026] The piston rod drives the moving contact assembly to contact the static contact assembly through the transmission mechanism. When the temperature of the temperature-sensing liquid drops, the reset mechanism drives the moving contact assembly to separate from the static contact assembly through the transmission mechanism.

[0027] In one embodiment, the transmission mechanism includes a torque link and a corresponding torque link fulcrum, wherein one end of the torque link is connected to the piston rod, and the dynamic contact assembly is provided at the other end of the torque link. The middle portion of the torque link is rotatably connected to the torque link fulcrum.

[0028] The reset mechanism is a return spring, which acts on the torque link. If the return spring is a tension spring, it acts on the same side of the torque link as the piston rod. Conversely, if the return spring applies a test force to the torque link, it acts on the same side of the torque link as the moving contact assembly. When the temperature of the main power contact drops, the temperature of the temperature-sensing fluid also drops, and the spring tension returns the tie rod to its original position.

[0029] In one embodiment, the moving contact assembly includes a moving contact insulator and a moving contact sliding plate mounted on the moving contact insulator. Preferably, there are two moving contact sliding plates, with a pressure spring disposed between the two moving contact sliding plates. The static contact assembly includes a static contact insulator and a static contact sliding plate mounted on the static contact insulator. The moving contact sliding plate is provided with a moving contact, and the static contact sliding plate is provided with two corresponding static contacts spaced a preset distance apart. The present invention utilizes two static contacts to achieve two types of control. For example, when the temperature of the temperature-sensing liquid rises, the moving contact is driven to contact and connect with the front static contact JD2, activating the heat exhaust fan. As the temperature of the temperature-sensing liquid continues to rise, the moving contact is driven to contact and connect with the rear static contact JD3, activating the heat exhaust fan and the cooling air conditioning fan to supply air to the main power contacts through the air duct, thereby automatically reducing the temperature of the main power contacts under high current conditions in the data center.

[0030] In one embodiment, the upper portion of the temperature-sensitive liquid container is hemispherical and the bottom is flat, the temperature-sensitive liquid expansion tube is connected to the upper portion of the temperature-sensitive liquid container, and the bottom is in contact with the copper plate conductor.

[0031] Please refer to Figures 2 to 4 The data center main power contact system of the embodiment of the present utility model includes a moving contact bracket, a main power contact, a heat dissipation unit, and a data center main power contact temperature sensor.

[0032] The main power contact is correspondingly arranged on the moving contact bracket. The moving contact bracket is preferably made of steel with a copper-plated surface, which conducts heat quickly and is conducive to the heat dissipation of the main power contact. The main power contact consists of two copper plate conductors, and a pressure spring is provided between the two copper plate conductors and the moving contact bracket. The surface of the copper plate conductor is silver-plated to further reduce the contact resistance. The pressure spring clamps the two copper plates to the static contact, reducing the contact resistance between the copper plate conductor and the static contact. The heat dissipation unit is used to dissipate heat from the main power contact. The data center main power contact temperature sensor is correspondingly arranged on the moving contact bracket. Pressure spring

[0033] As an implementation method, the moving contact bracket is further provided with a temperature sensor cover covering the data center main power contact temperature sensor.

[0034] The heat dissipation unit is electrically connected to the data center's main power contact temperature sensor. It includes a heat exhaust fan, an air conditioning fan, and a control circuit. The control circuit includes relays, disconnect switches, fuses, contactors, and thermal protection relays.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
