Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
The design of the delay triggering starting circuit of the acquisition terminal table is beneficial to reducing the energy consumption of equipment and prolonging the service life, because the acquisition terminal table can start the electric quantity acquisition function after the voltage of the power grid is stable or reaches a preset threshold value; through the cooperation of the modules (comprising a power module, a delay trigger starting circuit module, an electric quantity acquisition module, a data processing and storage module, a communication module and a control module) which are arranged in the acquisition terminal, the electric quantity acquisition terminal of the delay trigger starting circuit can realize accurate electric power data acquisition and storage under specific conditions, and data are transmitted to a management system or other equipment through a communication interface for analysis and processing, so that the functions of real-time measurement, data storage, remote communication and the like of electric power parameters are realized;
However, the types of equipment in the electrical cabinet are more, heat in the cabinet can be overlapped, so that the temperature in the cabinet is higher (the temperature of each equipment is relatively higher), and the heat dissipation of the acquisition terminal meter and each equipment is conventionally realized by adopting a fan heat dissipation or water cooling heat dissipation mode;
When more equipment is arranged in the electrical cabinet, the cooling effect of the fan on the acquisition terminal meter is not obvious; the water cooling heat dissipation has a good heat dissipation effect, the pipeline is attached to the equipment for heat exchange and cooling by introducing a refrigerant into the pipeline, but the pipeline cannot be attached to all sides of the equipment in a contact manner at the same time, so that the contact heat exchange effect is low, meanwhile, after the refrigerant exchanges heat for a long time, the temperature of the refrigerant can be increased, the refrigerant is generally cooled in an auxiliary manner by a semiconductor refrigeration piece, so that the refrigerant is guaranteed to have a good heat exchange and cooling effect, but water vapor in the air in the electric cabinet is condensed when encountering the surface of the water cooling pipeline with a low temperature, so that water drops are formed, and the risk that the water drops drop into other electric equipment or sensitive equipment in the electric cabinet and cause short circuit or fault exists; in view of the deficiencies in the prior art, the following improvements have been made for this purpose.
Referring to fig. 1 to 10, the embodiment provides an electric quantity acquisition terminal with a delayed triggering start-up circuit, as shown in fig. 2, including an acquisition terminal meter 100, and a protective shell 101 installed in an electrical cabinet (not shown in the figure), wherein the acquisition terminal meter 100 is installed inside the protective shell 101, and the protective shell 101 is made of glass fiber and can play a role in heat insulation; the whole protective housing 101 is composed of a bottom plate 101a and a shell 101b, the shell is detachable, the later maintenance work of the acquisition terminal meter 100 is facilitated, and a sealing gasket 101c is arranged at the juncture of the bottom plate 101a and the shell 101b, so that a closed space is formed inside the protective housing 101;
Notably, the protective housing 101 is installed in an electrical cabinet (electrical cabinet is not shown), the acquisition terminal meter 100 is installed in the protective housing 101, and heat generated by other devices in the electrical cabinet cannot enter the protective housing 101 due to the characteristics of heat insulation and sealing design of the protective housing 101, and even if the high temperature is generated by superposition of heat generated by other devices, interference cannot be formed on the acquisition terminal meter 100 in the protective housing 101, so that the service life of the acquisition terminal meter 100 is prolonged;
Meanwhile, as shown in fig. 1, the cooling mechanism 200 is further included, which is disposed outside the protective housing 101, and the cooling mechanism 200 is integrally located outside the electric cabinet, and is used for inputting air flow outside the electric cabinet into the closed space of the protective housing 101, and enabling air in the closed space to flow and be circularly discharged outside the electric cabinet, that is, the cooling structure can circulate the air flow inside the protective housing 101 and the air outside the electric cabinet, so that air with relatively low temperature outside the electric cabinet can enter the protective housing 101 and dissipate heat of the acquisition terminal meter 100; that is, on the basis that the temperature emitted by other devices in the electrical cabinet does not enter the protective shell 101 and affects the acquisition terminal meter 100, the heat generated by the acquisition terminal meter 100 is further discharged through the setting of the cooling mechanism 200, and air outside the electrical cabinet is pumped into the protective shell 101 to radiate the acquisition terminal meter 100, so that the acquisition terminal meter 100 can work normally, and the service life of the acquisition terminal meter 100 is prolonged.
