Hertz Three Phase Field Deactivator Secondary Current Injection Test Device

Product Description

Product Description

HZJB-430 handheld relay protection tester is mainly used in power grid companies, power plants, electric construction companies, comprehensive security manufacturers, petrochemical companies, rail transit traction power supply system and other users of electrical secondary equipment operation and maintenance maintenance debugging work. It is a set of domestic electric power industry standards, high degree of automation, advanced technology, high-end testing equipment. It is powered by built-in high-capacity lithium battery, lightweight and compact, easy to operate, especially suitable for outdoor maintenance and testing of power intelligent terminal devices in distribution network system, and can verify the protection action logic of terminal devices.

Product Features

1. It is lighter and smaller, easy to carry, and it is the newest tool for out debugging personnel;

2. Support a variety of online ways, through the RS232 serial port, RJ45 Ethernet interface, wireless WIFI three ways to control the tester;

3. The internal structure is modularized, and many imported components are used, so the output of the instrument is stable and reliable;

4. Built-in high-capacity rechargeable lithium battery, standby time is more than 8 hours, continuous working time is more than 4 hours;

5. A new chassis structure and operating panel design, using a number of shortcut function keys, easy and efficient operation;

6. Perfect self-protection function, current overheating alarm, voltage short-circuit protection, overheating protection, overload protection and so on;

7. Voltage and current menu. It can complete the testing of overcurrent protection, zero sequence current protection, voltage protection and other protection action logic functions of power intelligent terminal device. The amplitude, phase and frequency of each circuit voltage and current can be adjusted arbitrarily under the hand-controlled test mode;

8. State sequence menu. User freely customized test mode, the program provides 50 test states, all states of voltage, current amplitude, phase and frequency can be freely set by the user, switching between states by time control, key control or open-in contact control. The opening and closing of the two pairs of open and close quantities in each state can be freely controlled, which can be used to simulate the action of the protection exit contact, especially convenient for the single unit debugging of the terminal device.
