Abstract

The present invention discloses a thermal shock test system for a transmission project outdoor galvanization fitting. The system comprises a fitting heating assembly and an ice water spraying assembly. The test fitting heating assembly comprises a voltage regulation power current transformer, a current transformer and a test fitting, and the test fitting heating assembly establishes a conductive communication line through a lead. The ice water spraying assembly includes an ice water tank, an inlet pipe, a shower pipe, an outlet pipe and a test water tank. The thermal shock test system and method for a transmission project outdoor galvanization fitting fully consider the influence of the heating mode and the cooling speed on the thermal fatigue properties of the transmission project outdoor galvanization fitting and provide a thermal shock test design rule through combination of the through-flow heating and the spraying ice water mixture cooling to more accord with the real operation condition of the transmission project outdoor galvanization fitting so as to effectively guide the development of the thermal fatigue property test of the transmission project outdoor galvanization fitting and the design of the through-flow fitting and prevent the through-flow fitting from cracking and damaging caused by continuous accumulation of the interior thermal stress in the extreme cold and hot alternating environment.

Description

technical field [0001] The invention relates to the detection field, and more specifically, to a thermal shock test system and method for outdoor current-carrying fittings used in power transmission projects. Background technique [0002] At present, the flow fittings of substations and converter stations in my country's power transmission and transformation projects are usually composed of indoor and outdoor areas. At present, the natural environment of some project sites is harsh, and the climate is cold in winter, and the extreme temperature can reach -42°C. Low temperature environments can have severe effects on metallic materials. For the flow-through fittings of substations and converter stations operating under extremely cold conditions, especially outdoor flow-through fittings, it is easy to cause the temperature to rise rapidly after the current is applied, but because the external ambient temperature is not constant, sometimes the flow-through fittings will be at ...
