Novel instrument insulation can

Abstract

The invention discloses a novel instrument insulation can. The insulation can comprises an inner casing and an outer glass casing, the inner casing is hung in the outer glass casing via connecting assemblies, a hollow interlayer is formed between the inner casing and the outer glass casing, the top wall of the inner casing is connected with the top wall of the outer glass casing via connecting assemblies, the bottom wall of the inner casing is connected with the bottom wall of the outer glass casing via connecting assemblies, each connecting assembly comprises a stud, a holddown spring and internal and external fastening nuts, the inner walls in the left and right sides of the inner casing are provided with conductors respectively, and the outer walls in the left and right sides of the outer casing are provided with induction coil discs at positions corresponding to the conductors respectively. Electromagnetic induction heating and the heat insulated hollow interlayer are used to greatly reduce heat loss of the insulation can, the heat insulating ability is improved, and a heating line is avoided for circuit break due to heat fatigue in both cold and hot environments simultaneously.

Description

Technical field [0001] The invention relates to the technical field of instrument insulation, in particular to a new type of instrument insulation box. Background technique [0002] Instrumentation equipment is often used in special environments. Whether it is outdoors in northern cold regions, low-temperature production chemical plants, cryogenic liquid gas pipelines or underground freezing areas, the insulation of meters affects the accuracy and safety of survey data. For related technologies The current solutions fail to effectively solve the problems of heat loss and circuit thermal fatigue. Therefore, it is necessary to invent a new type of instrument insulation box. Summary of the invention [0003] The purpose of the present invention is to provide a new type of thermal insulation box for meters, which has excellent thermal insulation performance and can prevent the circuit from being broken due to thermal fatigue caused by simultaneous contact with cold and heat.
