1.System Introduction

HZBZ-IV automatic transformer comprehensive test system is technically used for routing test，type test and special test of transformers, including automatic test capability for ratio-voltage，direct current resistance, no-load loss measurement,induced over voltage withstａnd test，temperature rise test(10～35kV class distribution transformer). All the test items can be operated by the relevant transformer automatic comprehensive test syste.

The fully automatic model adopts PLC as the control core and industrial control computer as the man-machine interaction interface, which has the outstanding advantages of high reliability, intuitive interface, simple operation and perfect protective measures.

III.Installation and commissioning

1. After the production of complete sets of equipment is completed, preliminary installation and commissioning work shall be carried out to reduce on-site installation and commissioning time. The on-site installation and commissioning shall require the necessary assistance from the purchaser, and the supplier shall provide training to the demａnd side in order to be able to operate the equipment proficiently. The contents include: system overview, basic working principle of the system, operation and usage of equipment, inspection and maintenance of equipment, failure analysis and processing.

2. After trial operation or normal operation, technical personnel of both parties will test the technical indicators of the equipment.

Precautions

1. The equipment demander only needs to provide three : power distribution cabinet with frequency 50Hz±0.1 and current not less than 500A;

2 The grounding resistance of the installation site shall not be greater than 0.5 ohms; in order to maintain the integrity of the site, it is better to pre-ditch the cable trench in the control room and equipment area during the civil construction;

3. Delivering the equipment should also provide detailed technical documents, instructions for use, electrical installation plans and related information;

4. The unfinished matters are negotiated and resolved by the two parties.
