Overview

The comprehensive piano style industrial electrical experimental equipment is used for overload, short circuit, leakage locking, leakage action, and 1K resistance leakage time testing of explosion-proof switchgear in coal mines. It also provides zero sequence voltage and zero sequence current output, and has a testing platform for testing the leakage protection function and leakage action time of high-voltage distribution equipment. With relevant operating frames, it can also perform routine JDB and ABD8 plug-in inspections.

Product Details

Comprehensive piano style industrial electrical experimental equipmentFunction:

1. Switch on power supply, external power supply (optional according to user requirements).

2. This power supply consists of a fully controlled three-phase rectifier module, a phase-shifting trigger circuit, an automatic adjustment circuit, and an absorption circuit.

3. The transistor intelligent control module integrates complex automatic adjustment circuits, thyristors, and trigger circuits into one, and changes the thyristor by adjusting the magnitude of the control signal voltage

4. The size of the conduction angle of the tube enables the function of adjusting and automatically controlling the power supply.

5. The triggering circuit system, thyristor, and thermal conductive substrate are insulated and isolated from each other, with a dielectric strength greater than 2500V, making it safe and convenient to use. There is no phase sequence restriction at the input end of the three-phase rectification module. Suitable for resistive and inductive loads.

Comprehensive piano style industrial electrical experimental equipmentMaintenance and upkeep:

1. Key point one: Dust removal and cleaning

Electrical equipment dust removal is one of the items in electrical maintenance. Under the flow of air, the dust carried will adhere to electrical components, and the longer the time, the thicker the dust collection.

The attached dust collection can cause poor contact between electrical contacts. The closure of the contactor creates gaps, causing electrical equipment to overheat and other situations. Therefore, dust removal is an important task during the maintenance of electrical equipment.

2. Key point 2: Terminal fastening

Loose terminals are a common problem in electrical equipment under alternating cold and hot vibrations and same frequency vibrations. At the same time, virtual connection of terminals can lead to the risk of overheating of the circuit and burning of the switch. Therefore, during each maintenance, we should check whether the terminals are secure. Is the crimping tight? Is there any looseness.

3. Key point three: Testing and experimentation

Testing and assessment are common methods for checking whether electrical equipment can operate effectively. By operating the functions of electrical equipment, check whether the mechanical and electrical components are effectively coordinated and operate flexibly! During functional testing, the clearance between the adjustable and calibrated action mechanisms can be adjusted. By making appropriate adjustments and tuning, electrical equipment can achieve optimal performance.

4. Key point four: Replacement of vulnerable parts

During the implementation of electrical equipment maintenance, in addition to completing the aforementioned three steps, it is also necessary to check whether vulnerable components can work properly. For example, common situations include indicator lights not turning on, switch jamming, contactor noise, instruments, etc. Timely replace damaged electrical components and maintain normal operation of electrical equipment through preventive maintenance.
