Some battery testers on the market can only perform "capacity verification discharge," requiring the battery to be disconnected from the system for testing, while others only support online monitoring without assessing actual capacity. The HZFD-200 integrates both functions into a single d
The minimum temperature of HZBD-1177's cold bath reaches -70 ℃, far below the usage range of most engine coolants (usually below -45 ℃ is already an extreme requirement). The implementation of this indicator relies on the combination design of dual compressor refrigeration technology and anhyd
In the type testing and factory inspection of high-voltage electrical equipment, there is a test that appears "violent"—a high-voltage pulse lasting tens of microseconds is used to "strike" the device under test, observing whether the insulation can withstand it. This is the lig
One of the most prominent engineering values of HZLY-200A is the integration of four core operations at the transformer overhaul site into one device, significantly reducing the number of on-site equipment and coordination complexity.Implementation of four functions in oneFunction 1: Transformer oil
There are two main methods for measuring the internal resistance of batteries: direct current discharge method and alternating current injection method (ACIR). The HZNZ-100 adopts the AC injection method, which is not a random choice, but the only practical technical route under the key requirement
