Description du produit
The valve-controlled energy metering module is a type of energy metering module that integrates the functions of energy metering and valve control, but there is limited information about its specific definition and detailed working principle. Cependant, combined with the general characteristics of energy metering modules and the concept of valve control, some explanations and speculations can be made about valve-controlled energy metering modules.
Energy metering module: A device used to measure and record energy consumption, usually including components such as current transformers (CT), voltage transformers (VT), and metering chips. The energy consumption is calculated by measuring current and voltage, and the results are recorded in specific units (such as kWh).
Valve control: Usually refers to a device or system that controls the flow of fluids (such as gases and liquids). In power systems, although it does not directly involve fluid control, “valve control” may refer to a certain control function related to energy metering, such as remote control of the supply or cutoff of energy.
Features of the electric energy metering module
1. Collect multiple electrical parameters such as voltage, actuel, pouvoir, and electric energy in single-phase AC or DC, with complete information.
2. Adopt special measurement chip, effective value measurement method, and high measurement accuracy.
3. With RS-485 communication interface, optional TTL, 433M wireless communication.
4. The communication protocol adopts standard Modbus-RTU, with good compatibility and convenient programming.
5. Wide working voltage AC80～264V.
6. High isolation voltage, with a withstand voltage of AC:2000V.
7. Can be changed and customized according to customer requirements.
Application fields
Valve-controlled energy metering modules may be widely used in the following fields:
1. Smart grid: As an important part of smart grid, it realizes accurate metering and remote control of electric energy.
2. Demand response: In the power demand response system, the supply and demand of the power grid are balanced by remotely controlling the supply or cut-off of electric energy.
3. Energy management: In industrial, commercial and residential electricity consumption, it provides accurate energy metering data and remote control functions, which helps to achieve efficient utilization and management of energy.
4. Charging facilities: In charging facilities such as electric vehicle charging stations, it is used to accurately measure energy consumption and control the charging process.
Précautions
1. Technology update: With the continuous development of power technology and communication technology, the technology of valve-controlled energy metering modules is also constantly updated and improved. Donc, it is necessary to pay attention to its technical level and compatibility when selecting and using it.
2. Safety protection: Since the valve-controlled energy metering module involves the metering and control functions of electric energy, it is necessary to strengthen safety protection measures to prevent illegal access and operation.
3. Maintenance and management: Regularly maintain and manage the valve-controlled energy metering module to ensure its normal operation and accuracy.
8 fonctions d'autoprotection
1. Protection de limite de puissance d'entrée
Lorsque la puissance de la carte batterie est supérieure à la puissance nominale, le contrôleur limitera la puissance de la carte de batterie dans la puissance nominale pour éviter que le courant ne soit trop important et n'endommage le contrôleur., et le contrôleur entrera dans la limite de charge actuelle.
2. Protection de connexion inversée de la batterie
Le système ne fonctionnera pas une fois la batterie allumée à l'envers, et le contrôleur ne sera pas brûlé.
3. Protection contre les surtensions de tension d'entrée photovoltaïque
Le contrôleur éteindra automatiquement l'entrée PV si la tension à l'entrée du générateur PV est trop élevée..
4. Protection contre les courts-circuits d'entrée PV
Le contrôleur déconnectera la charge après un court-circuit de l'entrée du générateur photovoltaïque., et la charge reprendra automatiquement lorsque la condition de court-circuit sera effacée.
5. Protection de connexion inversée d'entrée PV
Lorsque la polarité du générateur photovoltaïque est inversée, le contrôleur ne sera pas endommagé et continuera à fonctionner normalement après avoir corrigé l'erreur de câblage.
6.Protection contre les surcharges
Lorsque la charge dépasse la puissance nominale, la charge retardera la protection de la sortie.
7. Protection anti-retour de charge la nuit
Empêcher la batterie de se décharger à travers la plaque de batterie la nuit.
8.Protection contre la surchauffe
Protection contre la foudre des téléviseurs
