Definitions
- This invention relates generally to the field of large electrodynamic systems, such as electrical power generators. More specifically, this invention relates to an improved connector for a combined electricity/ coolant junction in such a system.
- conduits that are fabricated out of electrically conductive material are used at certain locations to convey both the gaseous coolant and electricity.
- FIGURE 1 depicts an electrical connection at the parallel ring/main lead junction for such a generator model.
- Such connections are designed to be flexible, so as not to transmit vibration between the connected components, and gas tight, so as not to leak during operation.
- the conventional parallel ring coupling 10 depicted in FIGURE 1 connects a pair of parallel ring connectors 12, 14 both electrically and in terms of coolant communication to a main lead connector 16.
- Coupling 10 includes machined glass blocks 18, 20 that are formed over bolting hardware and are sealed by means of a silicone compound 22 to the respective connectors 12, 14, 16 and an external rubber insulation cover 24.
- a number of flexible electrical connectors 26, as shown in FIGURE 2 are electrically connected to the connectors 12, 14, 16 respectively by means of bolt 30, as is shown in FIGURE 1, to establish the desired electrical connection between the connectors 12, 14, 16.
- Tape 28 is preferably wound about the connectors 26 to insulate the connectors 26 from the coolant that will pass from connectors 12, 14 through the coupling 10 to the main lead connector 16 during operation.
- conventional couplings such as that shown in FIGURES 1 and 2 perform well during operation, they are relatively cumbersome and expensive. A need exists in this area of technology for an improved flexible, gas tight electrical coupling that is less expensive and time consuming to manufacture.
- a flexible, gas tight electrical coupling for a gas cooled electrodynamic system such as an electrical generator
- a gas cooled electrodynamic system such as an electrical generator
- a first connector element the first connector element being in communication with a first combined coolant and electrical path and having a first passage defined therein for a coolant
- a second connector element the second connector element being in communication with a second combined coolant and electrical path and having a second passage defined therein for a coolant
- a flexible tube for communicating the first passage in the first connector element with the second passage in the second connector element, the flexible tube having an outside surface
- an electrical connection for electrically connecting the first connector element to the second connector element, the electrical connection means being external to the flexible tube, whereby both coolant and electricity are conducted from the first connector element to the second connector element .
- FIGURE 1 is a fragmentary cross-sectional view depicting a conventional parallel ring coupling
- FIGURE 2 is a fragmentary cross-sectional view of the coupling depicted in FIGURE 1;
- FIGURE 3 is a fragmentary view of an electrical coupling that is constructed according to a first embodiment of the invention
- FIGURE 4 is a fragmentary cross-sectional view of a portion of the coupling that is depicted in FIGURE 3 ;
- FIGURE 5 is a fragmentary view illustrating an electrical coupling that is constructed according to a second embodiment of the invention.
- FIGURE 6 is a fragmentary view illustrating the electrical coupling that is depicted in FIGURE 5.
- a flexible, gas tight electrical coupling 32 for a gas cooled electrodynamic system such as an electrical generator is intended to provide both a coolant and a electrical connection between a single parallel ring connector
- Coupling 32 preferably includes a first connector element 38 that is in communication with a first combined coolant and electrical path, this being the single parallel ring connector 36. Coupling 32 further includes a second connector element 40 that is in communication with a second combined coolant and electrical path, this being the main lead connector 34 depicted in FIGURE 3.
- coupling 32 further includes a flexible tube 42 for communicating a first passage in first connector element 38 with a second passage that is defined in second connector element 40 so that coolant may flow during operation, without leakage, between parallel ring 34 and main lead connector 36.
- Flexible tube 42 includes an outside surface 44, shown in FIGURE 4, and is preferably fabricated from a flexible polymeric material, most preferably polytetraflouroethylene, which is also known by the brand name Teflon ® .
- flexible tube 42 could be fabricated from any other resilient plastic material that is heat- resistant and flexible.
- coupling 32 further includes a number of flexible electrical connectors 54, which are each secured to the first and second connectors elements 38, 40, respectively, by a number of connector bolts.
- electrical connectors 54 are external to flexible tube 42, in order to avoid exposure of connectors 54 to coolant, and reducing the amount of material and sealant that is necessary to achieve the combined coolant and electrical connection with respect to the conventional coupling shown in FIGURES 1 and 2.
- first and second sealing arrangements 46, 50 are provided for sealing the outside surface 44 of the flexible tube 42 with respect to the first and second connector elements 38, 40.
- first and second sealing arrangements 46, 50 are embodied as simple
- O-rings 48, 42 In comparison to the laborious application of the silicone compound that is necessary in conventional couplings such as that depicted in FIGURES 1 and 2, O-rings 48, 52 provide a simple, yet effective seal that prevents leakage of coolant during operation.
- Coupling 56 is designed to provide communication between a pair of parallel ring connectors 58, 60 to a single main lead connector, in the same manner as the conventional coupling that is depicted in FIGURES 1 and 2.
- Coupling 56 includes first and second connector elements 62, 64 and first and second flexible tubes 66 , 68.
- First flexible tube 66 is provided to communicate coolant from parallel ring connector
- Second flexible tube 68 is provided to communicate coolant between parallel ring connector 60 and main lead connector 61 via passages and connector elements 62, 64.
- a number of flexible electrical connectors 70 are provided to electrically communicate the first connector element 62 with the second connector element 64.
- Bolts 72 are used to secure the electrical connectors 70 to the respective connector elements 62, 64.
- sealing arrangements that are embodied as O-rings 74, 76 are provided to seal outer surfaces of flexible tubes 66 , 68 to the first and second connector elements 62, 64.
- electrical connectors 70 are external to the flexible tubes 66, 68.
