samples shall be selected according to 5% of the number of gasoline barrels

When sampling in bulk gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles,AlasteinPicture of dry-type transformer grounding wire, samples shall be taken according to 2% of the total number of barrels (bottles).

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

Alastein.What is the cause of power transformer core failure?

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times,AlasteinInstallation drawing of dry-type transformer, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

Sound in case of phase failure

Before no-load impulse closing, the transformer shall be placed for 24h, dry-type transformers mostly use silica gel waterproof casing, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.

demand.What is the wiring mode of dry-type transformer?

The equipment can eliminate the shortcomings found in the patrol inspection clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.

The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

Therefore, in the operation prevention and regulation of relay protection dry-type transformer,AlasteinDry type transformer of power plant, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.
