Definitions
- the present invention has its field of application in electric power distribution facilities, such as for instance electricity transformation centres, distribution centres, substations, etc., for the protection and operation of electrical circuits in general and, in particular, it refers to an electrical unit that comprises encapsulating in an insulating body of a series of elements, including amongst others one or two operating elements that enable the electrical circuit cutoff-connection-sectioning-grounding operation functions to be performed, as well as acting as an envelope integrating said insulating body, forming a module that may be expanded by connecting it to others.
- electric power distribution facilities such as for instance electricity transformation centres, distribution centres, substations, etc.
- Such switchgear used in electric power distribution networks is usually installed in metallic envelopes, called cells.
- Such switchgear comprises operating elements which perform the installation cutoff-connection-sectioning-grounding functions.
- such operating elements may be actuated to obtain the desired power distribution, prevent users being left without power or assure the protection of persons and such electrical equipment as transformers.
- every one of said operating elements has its own element of actuation, which may be performed both under the control of a hand-operated mechanism and of a triggering mechanism in response to a fault current.
- section switches are also used, which are further required to perform grounding functions.
- section switches are made up of two contacts that may be joined to let current pass or to leave a physical gap that is laid down by the safety regulation or the manufacturer in order to prevent current flow. Said section switches, however, are not able to perform the functions of a switch, i.e. to cut off the current when the circuit is under load or in the event of an overcurrent failure.
- the operating switchgear has both breakers and section switches with separate actuating means.
- part of this switchgear prefferably be encapsulated in solid insulation, such as insulating resin for instance, using vacuum or another fluid as the dielectric medium for performing the required operating functions mentioned above: cutoff-connection-sectioning-grounding executed respectively by section switches and breakers.
- patent application WO 0150563 which concerns a plurality of insulating resin bodies encapsulating a number of vacuum switches: some, corresponding to the connection-sectioning-grounding functions, are encapsulated in an insulating body along with their respective actuating mechanisms, while another different insulating body encapsulates the vacuum switch, which performs the cutoff-connection functions together with the respective actuating mechanism.
- the distribution bypass terminal and the main circuit busbars are also encapsulated in separate insulating bodies. Every one of these separate insulating bodies is installed inside a different compartment of the cell, said insulating bodies being connected by means of bushings which are part of the actual insulating bodies.
- the problem recurs of having to use a number of operating elements to perform the different cutoff-connection-sectioning-grounding functions, so that the cells incorporating the switchgear tend to be bulky.
- the disadvantage of the cells being bulky is exacerbated by the fact that the transmission elements for the actuating mechanisms for such operating elements are integrated in different compartments from those housing the operating elements, thus increasing the number of compartments in the cells, their size and, therefore, that of said operating switchgear in the electrical distribution network.
- EP1047169 describes a modular electrical unit according to the preamble of claim 1 comprising a moulded portion that encapsulates partially a metal vacuum container of the operating means (one of them performing interruption -connection - switching functions and the other performing the grounding function of the system), and two actuating elements (one for each of the switching devices) which are not encapsulated in any insulating body.
- the present invention is designed to resolve the afore-described problems, in every single one of the different aspects mentioned, constituting a modular electrical unit for installation and connection to other electrical equipment items in electricity transformation centres, distribution centres, substations, etc. which carries out at least cutoff-connection-sectioning-grounding operating functions in a single encapsulating.
- the electrical unit or module of the invention is claimed in claim 1 and comprises at least one solid insulating body inside which there are encapsulated the following components:
- an initial advantage of the invention on using a single insulating body for encapsulating the operating means, which perform at least the cutoff-connection-sectioning-grounding functions, is to considerably reduce the dimensions of the electrical unit, the amount of material needed and the cost of encapsulating, as well as its execution time, as the following savings are made:
- the operating means have their respective electrical contacts which are moving under the direct action of at least one busbar which acts as an element for transmitting the actuation of said operating means, there being a single actuating element adapted to trigger by itself either the cutoff-connection function or connection-sectioning-grounding function.
- That single actuating element is encapsulated in another solid body or insulating head, joined to the above-mentioned insulating body.
- the actuating element acts on one or more (actuation) transmission busbar, although a drive spindle transverse to the actuating element encapsulated in the insulating head may play a part in that transmission.
- the joint of the solid body and head is insulated by means of an elastic insulating element which permits relative movement between both.
- the two parts may be rigid or elastic and made from an insulating polymer material, for example, epoxy resin, silicone, polyurethane, NBR, etc.
- all the encapsulating, which may be coated with a conductive layer, is integrated in an envelope.
- the electrical unit may be composed not only of a single three-pole insulating body in which all the components of the electrical unit referring to the three phases are encapsulated, but also of an assembly formed of the union of three single-phase insulating bodies.
- the different single-phase insulating bodies of the three-pole assembly may be connected by means of metal parts or plates which are partly encapsulated in the insulating bodies, which at the same time permit the grounding of the electrical unit. These grounding plates are connected to the operating elements.
- the plates may be accessible from the outside of the envelope or else be completely in the interior of said envelope which integrates the three-pole assembly.
- the operating means are preferably implemented according to one of the three alternatives described below:
- the implementation possibilities proposed constitute a module, so that by means of the connecting elements which are accessible on the outside on one or more sides of the envelope, it is possible to enlarge the installation on one or more sides of the envelope, joining various modules by way of coupling means that depend on the sealing of the envelopes.
- the coupling between modules may be carried out for instance by means of collars, bushings or a link box like that is described in Invention Patent ES 2037590 .
- the coupling between the modules is done with a link box, so that in the event of a fault or failure of an electrical unit, this module may be easily replaced with a new one.
- a last but not least important advantage is that it is a compact modular electrical unit that may be easily replaced with a new one in the event of a possible deterioration of the same.
- the three-pole insulating body or three insulating bodies which make up a three-pole assembly inside an envelope which may contain a dielectric fluid and be sealed when the three-pole assembly is not coated with a conductive layer for the control of the electrical field, insulation between the bodies and prevention of internal defects, the distance is reduced between the envelope and the three-pole assembly, thereby achieving a compact operating switchgear.
- all the possible forms of implementation of the electrical unit proposed may comprise means capable of providing electrical voltage and current strength measuring functions, detection of the presence/absence of voltage, control, automation, etc.
- a modular electrical unit which comprises at least one insulating body (1) constructed with a polymeric insulating material, which may be rigid or elastic.
- the insulating body (1) encapsulates operating means (2) to carry out the cutoff-connection-sectioning-grounding functions, represented in figures 1-9 according to various possible implementations.
- the encapsulated operating means (2) in said insulating body (1) may consist of:
- first operating element (2a) which consists of an on-load cutoff switch and an automatic switch and a section switch/grounding section switch, as may be the case, for instance, of a vacuum switch, consisting of a vacuum bottle with two electrical contacts (11, 12), one being a fixed contact (11) and the other a moving contact (12).
- a vacuum switch consisting of a vacuum bottle with two electrical contacts (11, 12), one being a fixed contact (11) and the other a moving contact (12).
- all the cutoff-connection-sectioning-grounding operating functions are carried out by means of the single operating element (2a), reducing the size of the insulating body (1) where it is encapsulated and, therefore, the dimensions of the installations, as well as the amount of encapsulating material, encapsulating execution time and its costs.
- the insulating body (1) shown in figure 1 and, in greater detail, its interior in figure 2 encapsulates the operating element (2a) associated with main circuit busbars (5) and current bypass busbars (21).
- the moving contact (12) of said operating element (2a) is joined to the bypass busbar (21) which is accessible by way of a first connecting element (4), while the fixed contact (11) is joined to the main circuit busbar (5) which may have at least a second connecting element (6).
- These connecting elements (4, 6) are a component part of the insulating body (1) and they may consist of bushing of a female type, male type or their combinations, as shown in figures 1-5 , or else an overhead cable connection, as implemented in the first connecting elements (4) in the example in figure 6 .
- the moving contact (12) encapsulated in the insulating body (1) is in turn joined to an element (3) for actuating the operating means (2), by means of a busbar which acts as an actuating transmission element (10) fixed to the moving contact (12) by a joining piece (25).
- the actuating element (3) is encapsulated in an insulating head (13), made in polymeric insulating material, and it is adapted to actuate by itself either the cutoff-connection function or the connection-sectioning-grounding function.
- a drive spindle (17) transverse to the axis of symmetry of the insulating head (13) plays a part in the transmission of the actuation of the operating means (2).
- the joint between the insulating body (1) and the insulating head (13) is insulated by means of an elastic insulating element (16), for example, a rubber neck, as may be seen in figures 1 , 2 and 3 , which also permits the relative movement in a recess (15) between both the insulating body (1) and head (13) of the encapsulated unit.
- an elastic insulating element (16) for example, a rubber neck
- the electrical unit may be formed of three single-phase insulating bodies (1) which are joined by way of plates (9) partly embedded in each insulating body (1), thereby forming a three-pole assembly (8).
- the drive spindle (17) passes through each insulating head (13) thereby joining its respective elements (3) for actuating the operating means (2) so that they act in conjunction.
- said three-pole assembly (8) may be installed, for instance, inside a metallic envelope (7), which, in the event of being sealed, incorporates a dielectric fluid between this three-pole assembly (8) and the envelope (7) for the insulation between both and to prevent internal defects.
- connecting elements (4, 6) are accessible from the outside of the envelope (7), the former connecting elements being optionally disposed either horizontally or vertically, except when said connecting elements (4) consist of overhead cable connections, in this case with their connecting elements remaining inside the envelope (7) in order to carry out the connections with a bypass circuit in its interior.
- said connecting elements (4) consist of overhead cable connections, in this case with their connecting elements remaining inside the envelope (7) in order to carry out the connections with a bypass circuit in its interior.
- This modularity enables enlargements to be carried out on one or more sides of said module (14), in accordance with the options of figures 4 , 5 and 6 .
- it is a case of an insulated electrical unit in a high electrical strength insulation medium and a compact unit, thereby successfully reducing the insulation distance between different elements making up the electrical unit and the size of the installations.
- the connecting elements (4, 6) enable the installation to be enlarged by joining together various modules (14) and producing different electrical schemas, such as for instance a "ring main unit” or a subscriber schema.
- the first module (14) which acts as a service connection, may have second connecting elements (6) at the sides, being provided on one of the sides with male type bushings to which the supply cable terminals are coupled, while on the other side it has female type bushings, joining this first module (14) to the next one by way of the female type bushings (14) and by means of joining assemblies (18).
- the intermediate modules (14) in turn, have second connecting elements (6), which are female type bushings.
- the last module (14) may have second connecting elements (6) on one or more sides of the envelope (7); so that, in the event of their being provided on various sides, the second connecting elements (6) which remain free are sealed by means of plug to assure insulation, whereby the installation may be enlarged in the future.
- the dielectric fluid introduced between the envelope (7) and the three-pole assembly (8) considerably reduces the insulation distances, thereby preventing any internal defect that might damage the insulating body (1) in order to obtain a reliable compact electrical unit, and by using the joining assembly (18) as a means of coupling between various modules (14) the sealing of the set of said modules (14) is assured.
- the insulating body (1) plates (9) act as a terminal for grounding the operating means (2), as shown in figures 1-9 .
- the insulating body (1) plates (9) act as a terminal for grounding the operating means (2), as shown in figures 1-9 .
- a second way of conformation of the encapsulated electrical unit is that shown in figure 7 , where the insulating body (1) encapsulates operating means (2) of two operating elements (2a) and (2b).
- the first operating element (2a) consists of an automatic switch or on-load cutout switch, such as for instance a vacuum switch, and enables cutout-connection functions to be performed.
- the second operating element (2b) it is the case of a section switch/grounding section switch for executing the connection-sectioning-grounding operating functions, in which the dielectric medium where said functions are executed may be, for instance, a gas or a liquid.
- the first operating element (2a) comprises a fixed contact (11) joined to the main circuit busbar (5) and to the moving contact (12).
- the moving contact (12) also forms part of the second operating element (2b), which is provided with a third linearly moving contact (19) joined by means of a flexible connection (20) to the bypass busbar (21).
- This third contact (19) is also joined on another side to the actuation transmission element (10), which causes said linear contact (19) to move, establishing one operating function or another depending on the direction and advance of said linear movement.
- the movement of the actuation transmission element (10) in the opposite direction brings about the separation of the fixed (11) and moving (12) contacts of the first operating element (2a), leaving this in the cutoff function.
- the separation of the contacts (19, 12) of said second operating element (2b) takes place, determining the sectioning function.
- the second operating element (2b) also has a grounding contact (24) which sets it in the ground function, in conjunction with the third contact (19).
- FIG. 8 Another alternative embodiment of operating means (2), consisting of two operating elements (2a) and (2b), is that represented in figures 8 and 9 , each composed of vacuum bottles.
- the first operating element (2a) may consist of a vacuum switch, this being either an on-load cutoff breaker or automatic breaker, provided with a fixed contact (11) joined to the main circuit busbar (5) and a moving contact (12).
- the operating element (2b) is also another vacuum switch, but it constitutes a section switch/grounding section switch, comprising in turn a second fixed contact (27) joined to the grounding plate (9) and a second moving contact (26).
- the moving contacts consisting of two operating elements (2a) and (2b), is that represented in figures 8 and 9 , each composed of vacuum bottles.
- the first operating element (2a) may consist of a vacuum switch, this being either an on-load cutoff breaker or automatic breaker, provided with a fixed contact (11) joined to the main circuit busbar (5) and a moving contact (12).
- the operating element (2b) is also
