Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to a high and low voltage distribution cabinet with a temperature warning function. Background Art
[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.
[0003] When a large number of electrical equipment are installed inside the distribution cabinet, a large amount of internal space of the distribution cabinet will be occupied. Densely installed electrical equipment will generate a large amount of heat during operation. Since the distribution cabinet is generally a sealed or semi-sealed structure, short circuit or overload of electrical equipment will cause a large amount of heat to accumulate inside the cabinet in a short period of time. The lack of temperature warning device to remind operators to take corresponding measures will cause the equipment to work at high temperature for a long time, which may easily lead to damage to the electrical equipment in the distribution cabinet. Utility Model Content
[0004] The utility model aims to provide a high and low voltage distribution cabinet with a temperature warning function.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] It includes a cabinet body, the outer wall of the cabinet body is provided with an operation port connected to the internal cavity, the outer wall of the cabinet body is hingedly provided with a cover plate covering the operation port, the cover plate is fixedly provided with a telescopic cylinder close to the inner wall, the telescopic cylinder is provided with a sufficient amount of heat absorbent, the telescopic cylinder is sealed and slidably provided with a telescopic rod, the end of the telescopic rod is fixedly provided with an energized pointer, the inner outer wall of the cover plate is fixedly provided with a segmented light board along the sliding direction of the pointer, the pointer is electrically connected to the segmented light board, the outer wall of the segmented light board is fixedly provided with indicator lights of different colors in sections, the end of the segmented light board is fixedly provided with a buzzer alarm, and the cover plate is provided with a transparent observation window for aligning the indicator light.
[0007] By adopting the above technical solution, the telescopic cylinder has good sealing performance. When an unexpected situation occurs inside the cabinet and the temperature rises sharply, the heat absorber will quickly absorb heat and vaporize, thereby pushing the telescopic rod to move outward. When the telescopic rod moves, the energized pointer will pass through the indicator lights of different segments until it reaches the expansion limit of the heat absorber and stays in the specified segment. Since the cover plate is provided with a transparent observation window and the indicator lights are of different colors, the temperature ranges of different segments can be marked on the observation window, and the internal temperature of the cabinet can also be judged according to the color of the indicator light. When the internal temperature of the cabinet is too high and exceeds the specified threshold, the pointer will move to the end of the segmented light board. At this time, the buzzer alarm is activated, and the on-site operator is reminded through the dual warning of sound and light, which is convenient for the operation and maintenance personnel to quickly discover the dangerous situation and deal with it in time, thereby ensuring the long-term stable operation of the equipment.
[0008] Furthermore, a plurality of heat-conducting rings are extended from the outer wall of the telescopic cylinder, and the heat-conducting rings are arranged in parallel and spaced apart from each other.
[0009] By adopting the above technical solution, the setting of the heat-conducting ring effectively increases the contact area between the telescopic cylinder and the internal cavity of the cabinet, has a good heat-balancing effect, and ensures that the heat absorbent in the telescopic cylinder has a high-speed heat exchange to absorb and release heat.
[0010] Furthermore, the pointer includes a rod body, one end of the rod body is fixedly connected to the end of the telescopic rod, a mounting groove is provided in the extension direction of the end of the rod body away from the telescopic rod, a needle body is clamped in the mounting groove, the end of the needle body is electrically connected to the segmented light board, a return spring fixedly connected to the mounting groove is extended from a side of the needle body close to the mounting groove, a clamping ring is extended from the periphery of the needle body, and a clamping groove matching the clamping ring is provided on the inner wall of the mounting groove.
[0011] By adopting the above technical solution, the needle body and the segmented light board are electrically connected to ensure that the position change of the needle body can activate the indicator lights of different segments. The snap ring combined with the snap groove can effectively fix the needle body while allowing the needle body to rotate. The setting of the return spring enables the needle body to maintain a certain torsional force, thereby enhancing the tightness of the connection between the needle body and the segmented light board to ensure good electrical connection.
[0012] Furthermore, an electrode rod is fixedly provided on the outer wall of the needle, a pair of electrode contacts are provided on the outer edge of the electrode plate, the segmented light panel is provided with electrode grooves matching the electrode contacts, the electrode contacts are externally connected to a button battery, the electrode grooves are segmented and insulated from each other, and the electrode grooves are electrically connected to different indicator light settings.
[0013] By adopting the above technical solution, the electrode contacts on the electrode rod cooperate with the electrode slot to maintain a good fit and lock. Under the torsion of the reset spring, the electrode contacts only adhere to the electrode slot, ensuring that the electrode contacts and the electrode slot always maintain a good electrical connection, thereby ensuring the normal operation of the indicator light and the buzzer alarm.
[0014] Furthermore, limit plates are extended from the outer edges of both sides in the length direction of the segmented light panel, and the limit plates block the electrode rods.
[0015] By adopting the above technical solution, the setting of the limit plate has a good limiting effect, strictly limits the range of movement of the electric rod, prevents excessive temperature changes, and prevents the electric rod from slipping off the electrode slot to affect the normal operation of the equipment.
[0016] In summary, the beneficial technical effects of the utility model are:
[0017] 1. The equipment uses a retractable cylinder, telescopic rod, pointer, indicator light, and a transparent observation window, which makes it easy for operators and maintenance personnel to quickly discover dangerous situations and handle them in time, thus ensuring the long-term stable operation of the equipment.
[0018] 2. A heat-conducting ring is used to effectively increase the contact area between the telescopic cylinder and the internal cavity of the cabinet, ensuring the high-speed heat exchange of the heat absorbent in the telescopic cylinder to absorb and release heat;
[0019] 3. A return spring, electrode contacts and electrode slots are used to produce the effect. BRIEF DESCRIPTION OF THE DRAWINGS
