INTRODUCTION

MEWOI2540 central cabinet wireless high-voltage phase detector, alias: wireless central cabinet high-voltage phase detector, is specially designed and manufactured for handcart-type high-voltage switchgear (central cabinet) phase verification, this instrument adopts non-contact phase verification Technology, receiving phase detection data outside the central cabinet, you can complete phase judgment and phase sequence test for A, B, and C three-phase lines at the same time, avoiding the risk of direct contact between operators and high-voltage electricity in the cabinet, and eliminating the need for nuclear power. The safety hazard of the phase is guaranteed to ensure the safety of operators and equipment. Instrument operation is particularly simple, safe and fast. The instrument consists of host, detector group, monitoring software, USB communication line, etc. The host adopts a 3.5-inch true color LCD screen, which can display the phase, phase sequence and phase verification results on the same screen; at the same time, the three-phase display is clear and intuitive, making the test more convenient. Simple and easy. The monitoring software has the functions of online real-time monitoring, historical data query, phase indication, and phase sequence; it has the functions of reading, viewing, saving, and printing historical data.

Main Features

1. The non-contact phase detection technology is adopted to receive phase detection data outside the cabinet, which avoids the risk of direct contact between operators and high-voltage electricity in the cabinet, and ensures the safety of personnel and equipment.

2. Three phases of A, B, and C complete the phase verification at the same time, and the phase verification is accurate and easy to operate.

3. Using a 3.5-inch LCD color screen, it can display the phase, phase sequence, and phase detection results on the same screen, which is clear and intuitive.

4. Data storage function, can store 200 groups of data. USB interface data upload function, the stored data can be uploaded to the computer, saved and printed.
