Abstract
The utility model discloses an overall plugging structure of a temperature transmitter's temperature bulb. The structure provided by the utility model comprises a transmitter (1) and a temperature bulb part (6). The opening end of the temperature bulb part (6) matches the transmitter (1) through a stepped part (7). External diameter of the stepped part (7) is successively decreased from the top down. According to the utility model, a thermometer bulb and a simulated additional temperature rise device are both fixed in the temperature bulb of the temperature transmitter. The temperature transmitter's temperature bulb can be entirely drawn out along the direction of a lead wire so as to avoid winding temperature measuring errors caused by improper field assembly of the thermometer bulb.
Description
Technical field
The utility model relates to the assembly structure of a kind of temperature transmitter, particularly temperature transmitter.
Background technology
Transformer winding temperature gage needs to simulate additional temperature rise and is superimposed upon in oil temperature to obtain Transformer Winding temperature in thermometric process, and the additional temperature rise device of simulation is arranged in temperature transmitter thermometer bulb to reduce the impact of environmental baseline on additional temperature rise; And use scene because of condition difference, when having when mounted the wall-through hole of needs or walking pipeline, whole temperature transmitter is removed to wall-through hole or walks pipeline is unpractical.
Thermometer bulb parts in old structure in temperature transmitter are that transmitter below is installed, can not extract out along lead-in wire direction is whole, thermometer thermometer bulb can only be extracted out from the thermometer bulb parts of temperature transmitter, after through walls, reinstall in the thermometer bulb parts of temperature transmitter, because this work is operated by on-the-spot installer, often, because of misoperation, cause the additional temperature rise matched with devices of thermometer bulb and simulation to be made mistakes, cause winding temperature measuring error.
Summary of the invention
The technical problems to be solved in the utility model: when through walls for temperature transmitter, exist because thermometer thermometer bulb and the additional temperature rise device of simulation refill the problem that complexion easily produces error after separated, provide a kind of can be by thermometer thermometer bulb and the whole assembly structure plugging of the additional temperature rise device of simulation.
Technical solutions of the utility model:
The whole connect-disconnect structure of temperature transmitter thermometer bulb, comprises transmitter and thermometer bulb parts, and the openend of thermometer bulb parts coordinates by end difference and transmitter, and the external diameter of end difference successively decreases from the top down.
The additional heat riser of thermometer bulb components interior fixed installation simulation and temperature sensing part.
On the cylindrical of end difference bottom, have screw thread, and the stop nut being arranged on transmitter matches.
On thermometer bulb parts, clamp nut is installed.
The utility model beneficial effect:
Thermometer thermometer bulb and the additional temperature rise device of simulation are all fixed in the thermometer bulb parts of temperature transmitter, and thermometer bulb parts are to insert and install from the top of transmitter, when need are through walls, temperature transmitter thermometer bulb can be extracted out along lead-in wire direction is whole, after through walls, integral installation returns temperature transmitter again, thereby has avoided because of the improper winding temperature measuring error causing of thermometer thermometer bulb assembled in situ.
accompanying drawing explanation:
Fig. 1 is the schematic diagram of traditional structure.
Fig. 2 is structural representation of the present utility model.
embodiment:
Embodiment: the rear portion, lower end of transmitter 1 offers mounting hole 8, and below mounting hole 8 mounting limit nut 5, limited location groove on stop nut 5, the limit convex of installing by this groove and mounting hole 8 belows is along by stop nut 5 restrictions, it can not skidded off, and can freely rotate.Thermometer bulb parts 6 are cylindrical, lower end closed, and upper end open, the additional heat riser 3 of inner fixed installation simulation and temperature sensing part 2, temperature sensing part 2 is exactly thermometer thermometer bulb.The openend of thermometer bulb parts 6 is provided with end difference 7, and the external diameter of end difference 7 successively decreases from the top down, on the cylindrical of its underpart, has screw thread.Thermometer bulb parts 6 are inserted in mounting hole 8 from top to bottom, and then rotary stopper nut 5 is fixing by thermometer bulb parts 6, finally clamp nut 4 is installed on thermometer bulb parts 6.When needs are through walls, first clamp nut 4 is taken off, unscrew stop nut 5, the whole extraction of thermometer bulb parts 6 is through walls.
Claims (4)
1. the whole connect-disconnect structure of a temperature transmitter thermometer bulb, comprise transmitter (1) and thermometer bulb parts (6), it is characterized in that: the openend of thermometer bulb parts (6) coordinates by end difference (7) and transmitter (1), and the external diameter of end difference (7) successively decreases from the top down.
2. the whole connect-disconnect structure of temperature transmitter thermometer bulb according to claim 1, is characterized in that: thermometer bulb parts (6) the additional heat riser (3) of inner fixed installation simulation and temperature sensing part (2).
