Diesel generator set detection fake load

Diesel generatorsGroup test maintenance AC fake load:
All types of diesel generators and UPS (uninterruptible power) are all emergency spare power supplies after commercial failure or power outage. Most time the diesel generator sets and UPS (uninterruptible power) are in standby spare state. Once the power outage is required, the diesel generator set is required to start the power supply immediately, otherwise the spare diesel generator set will lose its meaning.
Practice has proved that enhances daily detection and maintenance of diesel generator sets to effectively avoid accidents. Only the establishment of a perfect diesel generator set testing and maintenance procedures, and the timing standard is maintained, maintained and tested, and it can prevent it.
According to the ZUI new survey of many grassroots maintenance personnel, the maintenance technology problem in the current power maintenance work is - the output power of all kinds of diesel generator sets and UPS equipment and the detection of electrical characteristics parameters have not been high-power communication. The fake load is effective and smooth, and only the performance of the diesel generator set or UPS (uninterruptible power) is issued after the power supply fault.
I. Diesel generator set detection and maintenance AC fake load use
Detect diesel generator set:
Unbalanced load capacity; steady-state voltage adjustment rate; steady-state frequency adjustment rate; transient voltage adjustment rate; transient frequency adjustment rate; voltage recovery time; frequency recovery time; diesel generator set continuous operation detection.
Note: Electrical characteristics are automatic detection, data is calculated from the load itself computer.
Detect UPS:
Output voltage regulator accuracy; output voltage imbalance; dynamic voltage transient range; overload capability; city battery switching time; bypass inverting switching time; backup time.
Note: Electrical characteristics are automatic detection, data is calculated from the computer itself computer.
Second, the main function of the exchange of exchange of maintenance with diesel generator set
Downtable protection function: Diesel generator set detection and maintenance AC hypotransmonded in general AC fake load, the load box, increase the intelligent control system, can perform the protection settings such as lacking, overvoltage, etc., once the device detected The parameters exceed the set parameters, and the device will issue a sound alarm and automatically shut down.
Intelligent control and data processing function:
(1) Automatic detection can be realized by performing parameter settings for the detection device.
(2) Monitor the electrical parameters of the measured equipment online.
(3) Data Transition: After the detection is over, the acquired data can be stored to the U disk.
(4) Data processing software function: Data processing software and detector are used. The detection parameters can be set, analyze and process the various electrical parameters, operational status, and abnormal records detected by the detector; intelligent queries, display, print graphs.
Query function: Query the diesel generator set detection data and retrieve an abnormal record.
Online communication: The detector can be connected to the upper computer via the RS232 / RS485 interface.
Parallel function: The same model can be paralleled, the device is equipped with the RS485 digital parallel interface, which is controlled by the host, and the detection process is recorded.
Third, the main feature
Safety: Diesel generator set detection and maintenance AC fake load is different from the general load box, is through solid state relay, switch-on / off non-contact switch control, power is a non-segregation, and does not generate an arc, the operator passes the keyboard Input, microcomputer issues instructions, solid state relays have no contact control, and the detection personnel do not have to touch any switches, and the security reaches 100%.
High intelligence: Diesel generator set detection and maintenance AC dummy load has the triple function of AC load and measuring instrument, data calculation, so that product performance has reached a high intelligence.
High detection data accuracy: Diesel generator set detection and maintenance AC fake load is load, instrument integration, real-time collection data, computer automatic generation data, data accuracy can reach 99.99%.
Accurate power control (power constant): Diesel generator set detection and maintenance AC fake load uses solid state relay to control power components, high-speed power sampling adjustment module acquisition, comparison data. According to the load power set by the system, the relay control is achieved by comparing the real-time sampling, the feedback power and the set power, and the power correction is performed.
Multi-function-integrated liquid crystal display: Diesel generator set detection maintenance AC fake load uses a large screen LCD LCD screen display, full Chinese menu prompt, detection, display the three-phase voltage, each phase of the test device, each phase current, and Power, each phase reactive power, each phase power factor, each phase frequency, neutral line current, total power, and three-phase line voltage.
Multi-CPU work mode: Using the Lord, from the CPU control method, the main CPU coordination uniformly completes the sample, calculates three-phase control tasks, respectively, from the CPU.
Excellent performance of power components: Using columnar-resistant power consumption elements, the advantage is that the thermal temperature coefficient is excellent, with better consistency, and the power factor can reach 0.99.
Portability: Small load size, small area and easy transport; use of a rotational, easy to move.
It can be set by the keyboard: load power, load operation, load various protection, etc. The measurement parameters of the load are input by the keyboard, and can be adjusted at any time, and each phase is 100% continuously adjustable.
The heat dissipation system is perfect: using forced air-cooled heat dissipation, the fan selects high-power axial fan, low noise, long life, MTBF is 20,000 hours. Automatic locking, the detection stops 3 minutes, the fan is automatically stopped, and the load is reliable.
The power supply is used in a rotary quick connector, which is convenient and reliable.
