Description

Transformer internal fault simulates collector
Technical field
The invention belongs to power industry experiment equipment, more particularly to a kind of main transformer internal fault simulation collector.
Background technology
During transformer normal work, transformer oil is filled with inside gas relay.Inner air should be excluded, when When transformer breaks down in the process of running, the transformer oil of fault point is decomposed, and the gas that it is produced is in gas relay Assemble in device and act gas relay.In order to judge that residual air or internal fault generation are not drained to obtain during maintenance Gas, when there is main transformer bulk gas protection act, should take gas sample carries out chromatography.The component of these gases and contain Amount is one of important evidence that judgement equipment whether there is failure and nature of trouble.There are different back dissolving rates to reduce different component Influence, it is necessary to gas sample is taken out within the time as short as possible, and is analyzed as early as possible so that judge power transformer interior fault property and The order of severity of failure, development speed and trend.But for the action of on-load voltage regulating switch gas relay light gas, due to its with Main transformer body working condition is entirely different, need not take gas sample, pneumatosis directly can be drained into slot signal.But by The probability of happening for actually encountering generation gas in gas relay in operation maintenance personnel is relatively low, and on-site training difficulty is big, dangerous high, Seldom actual to carry out gas collecting training, training is more based on theory, and live manipulative ability is weak.
The content of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, there is provided a kind of simple structure, small volume, be easy to mobile and grasp The main transformer internal fault simulation collector of work.
The present invention solve technical problem use technical scheme be:Main transformer internal fault simulation collector includes instrument The table ﹑ combination tool boxes ﹑ of cabinet ﹑ ten thousand take the inverse power supply ﹑ rows that become of gas pipe ﹑ and walk to take turns branch frame ﹑ oil case ﹑ conservator supports on ﹑, are characterized in work Left side above tool bottom of cabinet face is fixed with simulation aerogenesis apparatus, and the upper bracket of frame shape is fixed with above Tool Cabinet, Left side in upper bracket is fixed with collector box, and fuel tank is fixed with the right side of collector box, with connecing on the left surface of collector box Head connects the top of simulation aerogenesis apparatus with appendix, and check valve, check valve connection air entraining pipe, air entraining pipe are provided with collector box It is placed in fuel tank, fuel outlet valve is provided with below the right flank of fuel tank, gas relay, gas is fixed with above upper bracket The top of collector box is connected above relay with hollow soft siphunculus, in the right flank oil gas pipeline connection fuel tank of gas relay Top, conservator support is fixed with the left side of upper bracket, fixed-analog conservator, simulation oil above conservator support Oil filler point is provided with above pillow, the hole set up by conservator branch below simulation conservator connects gas relay with pipeline road Left surface, circuit board is fixed with the back side top of upper bracket, weight gas is provided with the upper right corner before circuit board and is moved Make lamp, light gas action lamp, alarm buzzer and signal home button.
The beneficial effects of the invention are as follows:Main transformer internal fault simulation collector is trained in power industry employee skills Cheng Zhong, can significantly lift the level of skill of power transformation operation maintenance personnel, reduce on-site training or the directly danger coefficient of operation.This The overall process of unit simulation gas shield action, disclosure satisfy that power transformation operation maintenance personnel takes gas to gas relay and collector box Simulated drill, good appearance is clean and tidy, small volume, and observation is convenient, and placement location chooses flexible, can be placed in interior, substantially reduces Training difficulty.
