Description
Technical Field
The utility model relates to a steam turbine device specifically is heat-preservation type instrument cabinet.
Background
The operation of the steam turbine cannot be monitored by various instruments, and in order to facilitate the installation and management of the instruments, the instruments led out from measuring points around the steam turbine are usually installed in an instrument frame or an instrument cabinet in a centralized manner, so that the maintenance and monitoring are facilitated.
However, the instruments are limited by the use of the environmental temperature, and when the instruments are used in cold areas and the lowest temperature is below-20 ℃, most of the instruments installed in an open instrument rack and a common instrument cabinet cannot display numerical values or even work, so that great potential safety hazards are caused to the safe and stable operation of the steam turbine, and personal and property losses are caused seriously.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a heat preservation type steam turbine instrument cabinet; this instrument cabinet can provide a suitable temperature environment for inside instrument, but also can remain stable temperature range, has simple structure convenient to use's characteristics.
The utility model provides a technical scheme is:
the heat preservation type steam turbine instrument cabinet comprises a cabinet body; the method is characterized in that: the front surface of the cabinet body is provided with an instrument glass window, the inner wall of the cabinet body is provided with a heat insulation layer, and the lower parts of two sides of the cabinet body are provided with an instrument pressure leading pipe joint and a cable interface sealing joint; the heat insulation layer is tightly attached to the inner wall of the cabinet body panel; the electric heater is arranged at the lowest part in the cabinet so as to dissipate heat upwards.
The instrument glass window is arranged on the surface of the cabinet body in an openable and closable manner through a hinge.
The utility model has the advantages that: the utility model provides an instrument cabinet can provide suitable operational environment temperature for the instrument to keep a stable temperature range, make the monitoring instrument of steam turbine normally work and show, and then eliminate the potential safety hazard. In addition, the device also has the characteristics of energy conservation, simple structure and convenient maintenance.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
The heat preservation type steam turbine instrument cabinet comprises a cabinet body 1 and two groups of electric heaters 3 inside the cabinet body, wherein a glass window 2 is arranged on the front surface of the cabinet body 1 and faces to each instrument (10 pressure gauges 7 are shown in figure 1) arranged in the cabinet body, so that the operation state of a steam turbine can be monitored from the outside, and heat loss on the instruments is reduced; the glass window is also arranged on the surface of the cabinet body through a hinge (omitted in the figure) so as to facilitate the maintenance of the instrument. A heat insulation layer 4 (preferably made of sponge heat insulation material) is fixed on the inner wall of the cabinet body panel to prevent heat in the internal space of the cabinet body from dissipating outwards. Instrument pressure leading pipe joints 5 (shown in the figure to be positioned on the left side face of the cabinet body) and cable sealing joints 6 (shown in the figure to be positioned on the right side face of the cabinet body; comprising 2M 40 cable joints, 3M 32 cable joints, 2M 25 cable joints and 1M 20 cable joints) which are communicated with each instrument one by one are arranged below the side face of the cabinet body 1, and the electric heater 3 is arranged below the inner part of the cabinet body, so that hot air can float upwards conveniently, and the temperature range in the cabinet body is maintained.
The utility model discloses a theory of operation is:
when the heater in the cabinet is electrified to work, heat is radiated to the inner space of the cabinet body; because the inner wall of the cabinet body is provided with the heat insulation layer, and the pressure guiding pipe and the cable are changed from the conventional direct open access at the bottom into the access at the side surface through the joint, the structural improvements can keep most of heat in the cabinet, and the heat loss is greatly reduced. Meanwhile, the configured electric heater has the function of automatic temperature sensing; when the measured temperature in the cabinet is higher than the set stop temperature, the work is automatically stopped, and when the temperature in the cabinet is reduced to the set start temperature, the work is automatically started, so that the temperature in the cabinet is always kept in a proper range. In addition, the glass window is additionally arranged on the front surface of the cabinet, so that the outward heat loss of the instrument arranged on the cabinet surface is avoided.
