High-voltage tank for high-voltage generation, including a strain gauge for tank pressure measurement
A housing for a high voltage tank has a boiler which is open on one side and a circuit board cover which closes the boiler. At least one strain gauge is arranged on or in the circuit board cover such that it is expanded or compressed with a pressure-induced deformation of the circuit board cover. A housing of this type is particularly suited as a high voltage tank for an x-ray emitter. An impermissible pressure in the housing for a high voltage tank can be determined easily and reliably.
1. A housing for a high voltage tank for high voltage generation, the housing comprising:
a boiler being open on one side;
a circuit board cover disposed to close said boiler; and
at least one strain gauge disposed on or in said circuit board cover such that said at least one strain gauge is expanded or compressed with a pressure-induced deformation of said circuit board cover.
2. The housing according to claim 1 , further comprising insulating oil contained on the inside of said housing.
3. The housing according to claim 1 , wherein said boiler is a Gastronorm container.
4. The housing according to claim 1 , further comprising a test circuit configured to detect changes in a resistance in said at least one strain gauge.
5. The housing according to claim 4 , wherein said test circuit comprises a Wheatstone bridge circuit.
6. The housing according to claim 1 , further comprising a safety circuit electrically connected to said test circuit and configured to switch off a high voltage generation upon detecting a change in resistance of said at least one strain gauge has reached a limit value.
7. A high voltage tank for high voltage generation, comprising:
a housing according to claim 1 ; and
a high-voltage transformer disposed in said housing.
8. A method for operating a high voltage tank, the method comprising:
providing a housing according to claim 1 with a high-voltage transformer in the housing;
generating high-voltages with the high-voltage transformer; and
monitoring the strain gauge of the housing and, when an expansion or a compression of the strain gauge exceeds a predeterminable limit value, switching off the high voltage generation.
