The utility model relates to an explosion-suppression type instrument converter case and belongs to the technical field of flow measuring devices for coal mines. The technical scheme is that the explosion-suppression type instrument converter case comprises a converter case cover (1) and a switcher case bottom box (2), wherein the converter case cover and the converter case bottom box are connected and closed through locking bolts to form a converter case body, and an arc-extinction painting layer is arranged on the inner surface of the converter case body. The explosion-suppression type instrument converter has the advantages that a converter case casing has the explosion-suppression and arc-extinction performance in accordance with the requirements for special environments containing explosive gases and including coal mines. When accidental explosion occurs in the under-mine measuring environment, the converter case can effectively protect safety of a converter and can avoid risks like secondary relative ex
