Description
Technical Field
The utility model relates to an intelligent cabinet body.
Background
In order to use the control device, the intelligent cabinet needs to meet specific temperature and humidity requirements, thereby ensuring long-term, stable and reliable operation of the device. For the existing intelligent cabinet body for protecting electrical equipment, the intelligent cabinet body cannot well process the relationship between temperature and humidity and keep long-term operation, and condensation can be generated in the cabinet body. If the temperature and humidity inside the cabinet can not meet the requirements of protected equipment, the risk of oxidation and corrosion of the metal part of the internal electronic and electrical components can be generated. Therefore, in order to maintain the electrical devices in the cabinet in a good operating environment for a long time, the intelligent cabinet and the electrical devices therein need to be maintained regularly. This inevitably increases the cost of after-market service and also extends the maintenance period.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve above-mentioned and/or other technical problem and provide a new intelligent cabinet body that is used for example intelligent circuit breaker electrical equipment, it can satisfy the requirement of the internal portion of cabinet electrical equipment in the aspect of temperature and humidity to ensure that these equipment can be stable for a long time and reliable operation.
According to the utility model discloses an aspect, the utility model provides an intelligent cabinet body, it includes: an outer protective plate having a protective plate sidewall; an inner frame disposed inside the outer protection plate, carrying a smart circuit breaker operating in a 10kV-1000kV voltage environment, wherein the inner frame has frame sidewalls, and the frame sidewalls are spaced from the protection plate sidewalls, forming a channel between the frame sidewalls and the protection plate sidewalls, the channel having a first aperture and a second aperture, wherein gas from outside the smart cabinet flows into the channel from the first aperture and flows out of the channel from the second aperture; and a heat exchanger disposed in the back panel of the intelligent cabinet, having an air inlet and an air outlet, wherein gas from inside the intelligent cabinet enters the heat exchanger via the air inlet, and temperature-adjusted gas exits the heat exchanger via the air outlet. The outside protection shield and the inner frame of the intelligent cabinet body form an effective double-layer ventilation heat insulation structure, which is helpful for an outside airflow inflow channel, and only the airflow needs to flow slowly, so that the heat insulation effect of the cabinet body can be effectively improved.
According to an exemplary embodiment of the invention, there is an air duct on the surface of the at least one electrical device in the direction of orientation of the air outlet, wherein the air outlet of the heat exchanger has a size that can cover all air ducts. Depending on the arrangement of the electrical equipment within the cabinet, the surface of one or more electrical equipment forms an air duct inside the cabinet for regulating the temperature of the electrical equipment. This promotes airflow within the cabinet, by which airflow passes over the surface of the equipment, effecting changes in the temperature of the equipment, such as rapid cooling of the equipment.
According to an exemplary embodiment of the invention, the height of the heat exchanger is set such that the air outlet of the heat exchanger covers all air ducts. This allows the air flow inside the cabinet, which is output by the heat exchanger, to pass as far as possible over the surface of the equipment, allowing a rapid adjustment of the temperature of the equipment, for example a rapid cooling of the equipment.
According to the utility model discloses an exemplary embodiment, the intelligent cabinet body still includes: an insulating material, wherein the insulating material is disposed within the channel. When the intelligent cabinet is in an extremely low temperature environment, such as an outdoor minimum temperature as low as-40 degrees, the insulating material disposed within the channel formed between the outer protective panel and the inner frame of the cabinet can advantageously ensure that the temperature within the cabinet is maintained within a desired range, such as within a range of 5 degrees to 55 degrees.
According to an exemplary embodiment of the invention, the first opening of the channel is remote from the ground, and the second opening is close to the ground. By locating the first opening of the external airflow inlet passage at a position remote from the ground, the insulating passage for the external airflow to enter the cabinet is facilitated to then flow out of the second opening near the ground, thereby improving the insulating effect of the cabinet.
According to an exemplary embodiment of the present invention, the air inlet of the heat exchanger is far away from the ground, and the air outlet is close to the ground. The air inlet of the heat exchanger is arranged above the air outlet, so that an air flow circulation is formed from the air outlet below through the electrical device to be temperature-regulated to the air inlet above.
According to an exemplary embodiment of the invention, the heat exchanger further has a control panel, wherein the control panel is arranged on a side of the heat exchanger having the air inlet and the air outlet. The control panel provides the possibility for an external operator to further configure and adjust the performance of the heat exchanger to improve the cabinet interior temperature and humidity.
According to an exemplary embodiment of the invention, the heat exchanger further has a communication interface, wherein the communication interface is arranged on a side of the heat exchanger having the air inlet and the air outlet. The communication interface provides the possibility for an external operator to further configure and adjust the performance of the heat exchanger to improve the cabinet interior temperature and humidity.
According to an exemplary embodiment of the invention, the heat exchanger is a parallel flow heat exchanger. The heat exchanger passively dissipates heat to the inside of the intelligent cabinet body to control the temperature of the inside of the cabinet body, ensures normal work of electrical equipment in the cabinet body, ensures positive pressure in the inside of the intelligent cabinet body, avoids the possibility that moist steam enters the cabinet body, and avoids the condition that condensation is generated on metal elements of the electrical equipment in the cabinet body and then oxidation is caused.
