5pa.
Because large-scale vacuum electric capacity is limited the serviceable life on high-power short-wave transmitter, during damage, need to change in time the large-scale vacuum electric capacity of backup, just can guarantee the normal operation of transmitter.In practical maintenance, often can run into the backup large-scale vacuum electric capacity of changing and connect after chilled water, find that there is the phenomenon of percolating water, therefore, just cannot normally work.
The main cause of large-scale vacuum electric capacity generation percolating water has the following aspects: 1, large-scale vacuum electric capacity dispatches from the factory from producer, vibration in transportation, causing that electric capacity internal water circuit unit has certain damage, cause under certain hydraulic pressure, there is seepage in tightness not.2, because large-scale vacuum electric capacity is long in the storehouse resting period, some large-scale vacuum electric capacity may be deposited several years, makes the O-ring seal in the inner water route of large-scale vacuum electric capacity aging, under certain hydraulic pressure, seepage occurs.3, owing to only carrying out DC voltage withstand test to backing up when large-scale vacuum electric capacity carried out maintaining in the past, and do not do water pressure test.4, there is no a kind of device of doing water pressure test.
This device is under certain hydraulic pressure, whether seepage to occur for ease of detecting large-scale vacuum electric capacity, guarantees the integrity of large-scale vacuum electric capacity.
Summary of the invention:
The purpose of this utility model is: backup large-scale vacuum electric capacity is carried out to water pressure test, guarantee the integrity of large-scale vacuum electric capacity.
The utility model is achieved through the following technical solutions:
A kind of large-scale vacuum electric capacity cooling water pressure test unit, because it is 750A that large-scale vacuum electric capacity allows maximum operating currenbt, the in the situation that of large electric current, will produce high temperature, so two pole pieces of electric capacity need carry out water cooling, it is 5 * 10 that the inside of cooling water channel allows maximum hydraulic pressure
5pa, this device is under certain hydraulic pressure, seepage can not occur for ease of detecting large-scale true appearance electric capacity, guarantees the integrity of large-scale vacuum electric capacity.The technical characteristics of this device is: have a water tank (1), radiator drain (2), pressure water pump (3), tensimeter (4), pumping line (5), water container backwater pipe (6), valve (7), large-scale vacuum electric capacity (10), water tank, radiator drain, pressure water pump, tensimeter, pumping line, large-scale vacuum electric capacity, water container backwater pipe, valve are connected successively, form a closed water route for sealing relatively, just form a whole set of water pressure test unit.Opening pressure water pump, is increased to 5 * 10 by the hydraulic pressure of inside, large-scale vacuum electric capacity water route
5after Pa, stop, keeping pressure 10 minutes, confirm that large-scale vacuum electric capacity inside is non-leakage, detection is passed through.
In the utility model, described large-scale vacuum electric capacity cooling water pressure test unit, is characterized in that: valve (7) is serially connected in water container backwater pipe (6), and when turn-offing this valve, the water pressure of large-scale vacuum electric capacity inside can rise gradually.Water tank (1), pressure water pump (3), tensimeter (4), valve (7) are installed in to one movably in go-cart, be convenient to each large-scale vacuum electric capacity in different transmitters to carry out the hydraulic testing, and the hydraulic testing to backup large-scale vacuum electric capacity.
In the utility model, described large-scale vacuum electric capacity cooling water pressure test unit, it is characterized in that: pressure water pump (3) is connected with radiator drain (2) and pumping line (5), opening pressure pump power, water pump just can be to the inner water that injects certain pressure of large-scale vacuum electric capacity.In the situation that water outlet end valve (7) is closed, the water pressure that can raise gradually, can meet the required pressure requirement of large-scale vacuum electric capacity.
In the utility model, described large-scale vacuum electric capacity cooling water pressure test unit, is characterized in that: tensimeter (4) is installed on device and is attempted by pumping line (5) above, be convenient to directly read water pressure value, accurately reading.
