Abstract
The objective of the utility model is to provide a detection device capable of performing temperature-sensitive cable safety detection in an explosion-proof environment. The detection device is characterized in that a detection clamp (1) of the detection device is arranged on a heat storage block (2) which is connected with a heater (3). The heater (3) is connected with a power supply (4). The heat storage block (2) is additionally arranged so that a function of performing safety detection on a temperature-sensitive cable under the condition of turning off the power supply (4) is possessed. Therefore, safety detection on the temperature-sensitive cable in the explosion-proof environment is met.
Description
Technical field:
The utility model relates to a kind ofly can carry out the pick-up unit of temperature sensing cable safety detection under explosion-proof environment.
Background technology:
The pick-up unit of traditional temperature sensing cable is due to self need to be with power supply, so can not use under explosion-proof environment when detecting.
Technology contents:
The purpose of this utility model is to provide a kind ofly can carry out the pick-up unit of temperature sensing cable safety detection under explosion-proof environment, it is characterized in that: the detection folder (1) of pick-up unit is on heat storage blocks (2), heat storage blocks (2) is connected with well heater (3), and well heater (3) is connected with power supply (4).When temperature sensing cable is carried out to safety detection, first switch on power (4) make well heater (3) heat heat storage blocks (2), when the temperature of heat storage blocks (2) reaches rated temperature, cut off the electricity supply after (4) pick-up unit is brought in explosion-proof environment the temperature sensing cable in this environment is detected, because this timer is not charged, and the stored heat of heat storage blocks (2) is enough to meet the needs that detect, so this device has been realized under explosion-proof environment, temperature sensing cable is carried out to safety detection.
Of the present utility model 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 having increased heat storage blocks (2).Thereby met under explosion-proof environment the safety detection to temperature sensing cable.
The utility model can be perfect like this: between heat storage blocks (2) and well heater (3), be connected temperature controller (5).Well heater (3) can be when heat storage blocks (2) reach rated temperature automatic cut-off power (4) current supply circuit.
The utility model can also be perfect like this: with detecting between the folder heat storage blocks (2) of (1) and the heating power supply (4) of well heater (3) with being connected and separated difunctional (6).Connection and separated difunctional (6) can facilitate being connected with separated of casing (7) of pick-up unit and charged (4).
The utility model can also be perfect like this: detect the both sides of folder (1), one side is positioned on heat storage blocks (2) one planes, with this plane of heat storage blocks (2) be that opposite side forms and detects folder.Such structure is more reasonable in the utilization of heat energy.
