What is the inclened angle of buchholz relay?
To enable any gases generated within the transformer to bubble along the pipe towards the expansion tank. The Buchholz relay itself isn't angled; it's the pipe in which its fitted.
Why buchholz relay is inclened at some angle?
The Buchholz relay is installed in an inclined position because of buoyancy. Slightly inclined so the gas bubbles will flow to the cover and then to the Buchholz relay and not stay in a pipe corner.
What is a function of a Buchholz relay?

So they are only used (1) where there is an expansion tank and, (2) in substations, where the associated protection relays can be installed.
Why to use buchholz relay in hermatically sealed transformer?
Buchholz relays are used with oil-filled transformers, and these types of transformerare not normally hermetically sealed, because the oil must be allowed to expand and contract with changes in temperature, and must be able to displace air within the tank. Air vents are provided for any resulting air displacement, and are normally fitted with silica-gel chambers to ensure any air entering the transformer when the oil contracts is dry.Buchholz relays are normally fitted in an inclined pipe between the main tank of the transformer and an elevated expansion tank, so that any gases formed within the tank pass up that tube and are collected within the Buchholz relay's chamber. A Buchholz relay is designed to set off an alarm in the event of a loss of oil or an excessive collection of gas within the relay; a further fall in oil level, or a catastrophic explosion within the tank, will cause the Buchholz relay to disconnect the transformer.
