How to Test and Protect in the Wild Without Power Supply? Built in 20Ah Lithium Battery Artifact

For electrical engineers who conduct high-voltage tests in the field all year round, "finding a power source" is often more torturous than the testing itself.

Whether it's photovoltaic power plants in the vast Gobi Desert, wind turbines lining the mountains, or rural power grid overhead lines extending for dozens of kilometers in the wilderness, there are often no 220V mains sockets on site. In the event of a power outage for maintenance, the entire switchgear and transformer are in a power-off state, and traditional relay protection devices cannot be plugged in, becoming "iron lumps" on the spot.

In the past, in order to solve the power supply problem, the maintenance team had to grit their teeth and bring a small gasoline generator. Not only is it dirty and heavy, occupying the trunk, but it often takes a long time to light up when starting with a rope in the wild; What is even more frightening is that the voltage output by the generator often fluctuates, making it extremely easy to burn out the precision testing instrument motherboard on the spot.

The emergence of HZJB-1700 handheld three-phase relay protection tester has completely cut off the instrument's dependence on external power lines!

20Ah ultra large power lithium battery, supporting continuous operation for 8 hours

The HZJB-1700 revolutionary integrates an industrial grade 20Ah ultra large capacity power lithium battery pack into a portable body weighing only 2.75kg:

Ultra long off grid endurance: fully charged once, can continuously output three-phase voltage and current on site for up to 8 hours;

Worry free all day field work: capable of handling the constant value review and whole set transmission of dozens of microcomputer protection devices, fully supporting high-intensity inspection tasks throughout the day;

Dedicated fast charging: Equipped with a DC 16.8V dedicated intelligent fast charging adapter, it can quickly recharge during nap or transition time.

Test anytime, anywhere, when turned on

With the powerful built-in lithium battery, the on-site working mode has been completely changed:

Arriving at the testing site eliminates the tedious process of placing cable reels, pulling sockets, and debugging generators;

Place the instrument directly on the switchgear panel or ground, press the power button for a few seconds to enter the system;

Connect the testing line, immediately carry out protection setting verification, and after testing and packaging, rush directly to the next location.

From "searching for electricity on the ground" to "on-site testing", the HZJB-1700's hardcore lithium battery endurance allows field electrical testers to truly experience the calmness and efficiency brought by technology.
