Description
Technical field
This utility model relates to hydroelectric generation Automation Elements technical field, specifically a kind of easy-disassembling-assembling hydraulic turbine bearing shell temperature detecting resistance.
Background technology
In hydroelectric generation production process, the monitoring of turbine-generator units bearing bush temperature is taked to be to ensure that the important means of unit safety operation, general hydroelectric power plant has all designed the protection of unit bearing bush temperature, the protection of unit bearing bush temperature, direct action tripping grinder will be started when unit running process intermediate bushing temperature increases to over protection definite value. therefore to guarantee the reliability of bearing bush temperature protection act, all need in conjunction with Overhauling for Hydraulic Generator Set every year bearing shell temperature detecting resistance is verified, it is ensured that the accuracy of measured temperature. the temperature detecting resistance in the past adopted generally is made up of temperature detecting resistance probe and cable for measuring temperature two parts, probe is arranged in the thermometer hole of measured bearing shell, measure signal and cause in the signal processing apparatus outside unit by cable, general temperature detecting resistance probe and cable design for integral type, owing to hydraulic turbine bearing shell is installed in the oil groove of unit each portion bearing, apart from each other from temperature measuring equipment, often the configured cable of temperature detecting resistance will not be oversize, it is connected so generally need to separately add cable with temperature detecting resistance, method of attachment is usually and is wound around at cable core two ends or welds together, insulation processing is carried out again with adhesive tape wrapping, because connection construction quality and unit operation oil stream wash away, often introduce junction cable core get loose or break, signal circuit is caused to loosen or broken string, temperature thermometric value saltus step and disappearance. and in junction, cable need to be disconnected again when every year temperature detecting resistance being verified, take out temperature detecting resistance and verify, bring great inconvenience to replacing, verifying work, waste time and energy, increase repair and maintenance person works amount. additionally traditional hydraulic turbine bearing shell temperature detecting resistance adopts epoxy resin to be encapsulated in bush temperature detecting hole by temperature detecting resistance probe, it is prevented that move because vibrating in unit operation. from junction, cable need to be cut off when carrying out temperature detecting resistance replacing, verification every year, do open loop epoxy resins, could take out and verify into temperature detecting resistance row, owing to epoxy resin material is firm, survivable taking-up, often result in resistance and damage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy-disassembling-assembling hydraulic turbine bearing shell temperature detecting resistance, taking-up temperature detecting resistance can be mounted and dismounted conveniently and efficiently verify, shorten the time of equipment replacement and repair and maintenance, reduce the human and material resources of inspection Job engagement, can ensure that connection is reliable, measured value is accurate simultaneously.
This utility model such as techniques below scheme solves above-mentioned technical problem:
The easy-disassembling-assembling hydraulic turbine bearing shell temperature detecting resistance of this utility model, including temperature detecting resistance probe, signal cable, described signal cable is divided into two sections, and connected by cable connector, wherein another termination detection equipment of a segment signal cable, the other end of another segment signal cable connects the afterbody chip of temperature detecting resistance probe, and the outer body socket hollow bolt of described temperature detecting resistance probe, threadeds with the thermometer hole of hydraulic turbine bearing shell in the outside of this hollow bolt.
Cable connector described in the utility model is made up of public plug and female, and adopts contact pin type structure, and plug inside is equiped with sealing ring.
This utility model temperature detecting resistance, by using a cable connector and hollow bolt, can carry out the installation of temperature detecting resistance, replacing and verifying work quickly and easily, use manpower and material resources sparingly, the reduction of erection time.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model hydraulic turbine bearing shell temperature detecting resistance.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model hydraulic turbine bearing shell temperature detecting resistance is further described.
As shown in Figure 1, the easy-disassembling-assembling hydraulic turbine bearing shell temperature detecting resistance of this utility model, including temperature detecting resistance probe 1, signal cable 2, signal cable 2 is divided into two sections, and connected by cable connector 3, wherein another termination detection equipment of a segment signal cable, the other end of another segment signal cable connects the afterbody chip of temperature detecting resistance probe 1, outer body one hollow bolt 4 of socket of temperature detecting resistance probe 1, threadeds with the thermometer hole of hydraulic turbine bearing shell 5 in the outside of this hollow bolt 4.
The cable connector 3 that this utility model adopts is made up of public plug and female, and adopts contact pin type structure, and the inside of two plugs is all equiped with sealing ring, public plug and female and uses threaded, it is ensured that firm and reliable connection.
During installation, 1 body of being popped one's head in by temperature detecting resistance is inserted in hollow bolt 4, at hydraulic turbine bearing shell 5 thermometer hole place tapping, is fixed on hydraulic turbine bearing shell 5 thermometer hole with thread connecting mode by hollow bolt 4. When to remove temperature detecting resistance and verify, cable connector 3 of only need to outwarding winding, unclamps hollow bolt 4 and namely can be taken off temperature detecting resistance probe 1.
By adopting this utility model temperature detecting resistance, the installation of temperature detecting resistance, replacing and verifying work can be carried out quickly and easily, use manpower and material resources sparingly, the reduction of erection time.
