Abstract
The invention aims to provide a detection device capable of conducting safety detection for a temperature sensing cable in an anti-explosion environment. The detection device is characterized in that a detection clamp (1) is positioned on a heat accumulation block (2); the heat accumulation block (2) is connected with a heater (3); the heater (3) is connected with a power supply (4), and has a function of conducting the safety detection for the temperature sensing cable in a condition of cutting off the power supply (4) as the heat accumulation block (2) is added, so as to satisfy the safety detection for the temperature sensing cable in the anti-explosion environment.
Description
Technical field:
The present invention relates to a kind of pick-up unit that can under explosion-proof environment, carry out the temperature sensing cable safety detection.
Background technology:
The pick-up unit of traditional temperature sensing cable is owing to self need have power supply when detecting, so can not use under explosion-proof environment.
Technology contents:
The purpose of this invention is to provide a kind of pick-up unit that can under explosion-proof environment, carry out the temperature sensing cable safety detection, it is characterized in that: the detection folder (1) of pick-up unit is on the heat accumulation piece (2), heat accumulation piece (2) is connected with well heater (3), and well heater (3) is connected with power supply (4).When temperature sensing cable is carried out safety detection, at first connecting power supply (4) makes well heater (3) that heat accumulation piece (2) is heated, when the temperature of heat accumulation piece (2) reaches rated temperature, cut off the electricity supply after (4) pick-up unit brought in the explosion-proof environment temperature sensing cable in this environment is detected, because this moment, device was not charged, and the stored heat of heat accumulation piece (2) is enough to satisfy the needs that detect, so this device has been realized under explosion-proof environment temperature sensing cable being carried out safety detection.
Of the present invention just possessed the function of temperature sensing cable being carried out safety detection under the condition of (4) of cutting off the electricity supply owing to increased heat accumulation piece (2).Thereby satisfied under explosion-proof environment, to the safety detection of temperature sensing cable.
The present invention can be perfect like this: be connected temperature controller (5) between heat accumulation piece (2) and the well heater (3).Well heater (3) can be at heat accumulation piece (2) (4) current supply circuit of cutting off the electricity supply automatically when reaching rated temperature.
The present invention can also be perfect like this: have to have between the heating power supply (4) of the heat accumulation piece (2) that detects folder (1) and well heater (3) and be connected and separate difunctional (6).Connection with separate difunctional (6) and can make things convenient for being connected and separating of casing (7) of pick-up unit and charged source (4).
The present invention can also be perfect like this: detect the both sides of folder (1), the one side is positioned on heat accumulation piece (2) one planes, with this plane of heat accumulation piece (2) be that opposite side forms and detects folder.Such structure is more reasonable in the utilization of heat energy.
