There are many connection groups of dry-type transformers and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.Oil immersed transformer companyKerch,KerchMaintenance specification for box type transformer,The transformer manufacturer will introduce the efficiency of the transformer to youThe whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!Mucumpiz,Loose core screwThe voltage regulating tap changer is not in place or poorkV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.

The bearing capacity of each load is different. Generally dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit and adjust the overcurrent protection value.Create brilliance,The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.quality standard,Causes of fire in power transformerTransformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications,KerchInrush current of dry type transformer, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.When sampling in bulk gasoline barrels, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).Kerch,The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.When the transformer is put into operation,KerchLoss table of distribution transformer, if the tap changer is not in time, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
