Technical Parameter

Certificate

DL/T 721－2013

Features

1. Local communication:

- The acquisition unit and the remote transmission collection unit on the line can communicate wirelessly, and the communication distance is more than 100 meters.

2.Ways to detect short circuit faults:

- The over-current catastrophe method: automatically tracks the load current without setting the operation parameters.

- The over-flow break method: can prevent the misoperation of reclosing inrush current and the sudden change of small current.

3. Detect grounding fault:

- Detect transient current at the moment of grounding and identify grounding fault.

4 Double CT structure:

- The electronic current transformer is used for measurement; the electromagnetic transformer is used for power collection, which increases the measurement accuracy and operation stability.

5. Three-phase time recording function:

- The synchronization progress of three-phase recording ≤50uS.

6. Zero-sequence current synthesis:

- The zero sequence current criterion is introduced into the grounding detection criterion to increase the accuracy of grounding detection.

7. Low battery voltage alarm.

8. Full-function 4A operation when battery free:

- For the data acquisition unit with battery failure, as long as the line current is greater than 4A, data acquisition unit will run with full function.

9. Bulk backup capacitance:

- When battery is full, the backup capacitance could maintain the full function data acquisition unit for 12 hours.

10. Auto-reset:
- 1min~48h optional for factory-setting, or intelligent restore (restore immediately after power supply resumed).

11. Hot-line handling:

- Not requiring special tools, standard insulated operating rods.

12. Display mode:

- LED light, flashing light.

Situation

Applicable to the power distribution automation renovation of the overhead line of 10kV distribution network, it can realize the function of judging short circuit and grounding fault, and has the function of recording wave, to realize fault backtracking and support big data analysis.

Introduction

As the first company in Hunan Province to be listed on SSE STAR Market, Willfar is the pioneer manufacturer in China that can simultaneously provide related industries with all kinds of advanced electricity, water, gas and heat metering products and meters for power distribution, power quality monitoring equipment, a full range of energy data concentrators, relay protection equipment, switchgear products and equipment related to metering automation system and all kinds of application systems as well as services which cover the demand of the whole process of energy production, distribution, transmission and consumption.

Willfar Information Technology Co., Ltd always focuses on customers and takes full control of products’ delivery and deployment, including the process of designing, testing and experimenting as well as the manufacturing process of raw material. We attach great importance to production control plan, potential failure mode and product reliability design which require us to implement the production approval procedure and control the production process strictly so as to ensure the products’ quality.

On November 4, 2013, President Xi Jinping, also general secretary of the Communist Party of China (CPC) Central Committee, visited Wasion in Changsha. He visited the product showroom and production workshops, where he talked with workers and labor models. Xi spoke highly of Wasion's achievements in product development and market expansion and encouraged the company to step up innovation in technology, management, product, marketing and branding.

So far, Willfar has 396 valid patents, of which 26 are invention patents, 240 pieces for utility model, 130 pieces for design and 442 software copyrights; it has also received 10 technical awards of provincial or ministerial level or above. Willfar has participated in the setting of 15 national industry standards, 10 of which have been published.

Willfar Information Technology Co., Ltd takes "smart manufacturing capability" as one of its core competing powers by realizing the whole process data tracing and full-lifecycle management of product design, processing, procurement, production, logistics and service via SCM, CRM and APS on the basis of ERP, PDM, PLM and MES.
