Constantly Innovating Four New Products of Chint Instrumentation through Provincial Appraisal

[China Instrument Network Instrument R&D] On February 6, 2018, Zhejiang Zhengtai Instrumentation Co., Ltd. assumed the provincial industrial new product appraisal meeting. At the meeting, all four new products of Zhejiang Zhengtai Instrumentation Co., Ltd. passed the appraisal.

It is understood that the new products passed the provincial appraisal are DJGL33-ZTY666.004 type concentrator (State Grid II type), DJZ666.003 type DC smart meter, DTZY666C-J.006 type three-phase four-wire fee control. Smart Watt-hour meter, DDZY666.019 type single-phase fee-controlled smart energy meter four energy meter and electricity information collection system terminal.

Among them, the overall level of DDZY666.019 type single-phase energy-saving smart energy meter has reached the international advanced level. The power meter firmware upgrade process uses digital signatures, encrypted transmissions, etc., to ensure the security and reliability of the firmware upgrade; pulse voltage withstand voltage level up to 10kV in line with IR46 requirements, using SAG (voltage dip) detection function to ensure the power grid 500ms After the interruption, it works normally. By detecting the real-time voltage of the super capacitor, adjusting the wake-up time of the MCU, detecting the opening event of the open cover and the open cover, real-time monitoring of power stealing can be realized; and various communications can be applied without changing the hardware and firmware of the power meter. The module meets a variety of data acquisition methods of AMI.

In addition, the other three achievements have also reached the domestic advanced level. In particular, the DTZY666C-J.006 type three-phase four-wire charge-controlled smart energy meter adopts a dual-core (parallel dual CPU) design independent of the measurement core and the management core to realize the separation of measurement and management functions and the object-oriented design and implementation of the management core. Independent upgrade of software modules and over-current protection technology prevent each module from working abnormally without affecting each other. The dot matrix LCD meets the user's personalized display requirements.

Founded in 1998, Chint Instrument Co., Ltd. is a state-level high-tech enterprise that integrates scientific research, production, and sales, and a leading supplier of energy measurement and control equipment, systems, and solutions.
