Description

"ELECTRIC POWER SUPPLY, MEASUREMENT AND CONTROL SYSTEM, AND THEIR EQUIPMENT USED IN THIS SYSTEM".

The present invention patent relates to a new system of supply, measurement and control of electric power, as well as to the equipment employed in said system, said system and equipment which is primarily intended to combat the theft of electric power.

As is well known, in Brazil in general, and more particularly in some regions of its territory, violence and the deterioration of socioeconomic indicators are increasing dramatically, and this situation has led to an increase in the rate of losses in the region. distribution of electricity caused by fraud.

In fact, the socioeconomic complexity of some regions, determined by factors such as inequality, violence, precarious access to water and sanitation services, credit defaults, among others, has contributed to consolidating a negative reality for women. electric utilities.

This is because, due to these social dynamics, coupled with an increasingly disorderly and uncontrolled land occupation, there is a spontaneous growth of new frauds in the distribution of electricity. And the thefts of electricity end up causing great damage to the utility companies. In other words, the increase in access to electricity is not corresponding to the increase in utility companies' revenues, and they are unable to effectively manage and solve this problem. As is well known in the art, the electric power coming from the power plants, when arriving in the cities, is sent to the substations, where it goes through voltage transformers that decrease its voltage. From these substations, the medium voltage, or medium voltage, distribution lines run through the city's distribution network, through wires installed on the poles, taking the energy to the streets. Before entering homes / buildings / establishments, the power still passes through other transformers (installed in some of these poles), which lower the voltage to 127 or 220 volts (low voltage or low voltage network). These low-voltage wires are then routed to electrical meter boxes (or light clocks) installed within the boundaries of homes / establishments, close to the sidewalk. And it is these meters that record the energy consumption of each consuming unit.

Energy thefts are usually obtained either by tampering with the measuring instruments themselves (light clocks), by changing the values they measure, or by deviations (commonly referred to as "cats" or "gambiarras") which they consist of the installation of a wire that captures and transmits electricity to the fraudster's home or establishment, before passing through the meter, thus not recording the consumption of this energy.

Often clandestine connections are apparent near the transformer or distribution circuit of the low voltage network, resulting in dangerous tangled wires. At other times, in more sophisticated facilities, these clandestine connections are embedded in the masonry; and in such cases, sometimes such connections are made in parallel circuit to the meter, so as to feed only part of the load consumed by the fraudster; Thus, the meter accounts for part of the consumption, raising no suspicion for the employee of the concessionaire company responsible for reading the meter. Such clandestine connections, in addition to causing the aforementioned financial losses, often also cause short circuits and fires, as they are generally carried out by technically unskilled persons, who additionally use inappropriate materials outside the safety standards. required by current regulations.

Regardless of the manner in which offenders take illicit electricity, the utility company is invariably the only one harmed by such fraudulent actions, and it must maintain a constant field technical staff to locate potential points where power theft is taking place, and take measures that at least somewhat inhibit such violations.

Several attempts to curb the theft of electricity have been undertaken. One of these is the replacement of electromechanical meters with high precision electronic meters to perform the tasks of measurement, recording, reading and billing, with which power consumption can be controlled automatically and remotely.

Another way to try to inhibit the occurrence of fraud is to externalize the meters, placing them closer to the distribution network, fixed on top of the poles, a solution that has been adopted by some concessionaires.

However, both of the above embodiments have caused consumers to object, as they are unable to read and monitor their own consumption.

Yet another way to try to curb power theft has been to provide the boxes that house the power meters with security devices that make it difficult for fraudsters to act (special keys, sensors, alarms, etc.).

As it turns out, the number of systems and

equipment already developed to try to inhibit the occurrence of fraud in the distribution of electricity, and a sample of these systems / equipment is represented here through the documents listed above, which are incorporated into the present patent application as illustrative of the current state of the art.

However, none of these systems / equipment was able to effectively solve the problem, all of which had some or some drawbacks; in fact, many of these systems known in the art present great constructive complexity, and consequently, relative difficulty of implementation; other systems are too costly, often making their actual practical use unfeasible; still others, more particularly those that foresee the installation of the unit's measurement set on top of the network poles, have not been widely accepted in the market, as they do not allow consumers to read and monitor consumption.

In order to obtain a definitive solution to the problem,

the present "ELECTRIC POWER SUPPLY, MEASUREMENT AND CONTROL SYSTEM, AND THEIR EQUIPMENT EMPLOYED IN THIS SYSTEM" has been created, these systems and equipment incorporating some features already present in systems and equipment known in the art but having a number of features. innovative features, which have resulted in a substantially safer way of supplying, measuring and controlling electricity from utility companies to consumers, their customers.

The system now innovated is based on the principle of inhibiting any attempted theft of electricity by sharing the damage caused by it among a certain portion of society; In other words, with the system now innovated, any attempted theft by a fraudulent consumer of a particular group of consumers will be immediately noticed by other consumers, who, being directly harmed by such fraud, will report and be oppose this practice and, as a result, will increasingly contribute to discouraging further future attempts at fraud.

To this end, the system object of the present patent foresees a multiplicity of suppliers / meters / controllers modules arranged by the city, each one fed directly by a respective transformer from the medium voltage network of the same, eliminating, therefore, the low voltage grid, each module being responsible for supplying electricity previously measured to a certain number of consumer units (houses, buildings or establishments), grouped by their proximity; These modules are installed at ground level, outside the territorial limits of the said units, and are provided with visualization means that allow the reading and monitoring of the individual consumption of each consuming unit. sensing means conveniently interconnected with an automation system capable of disrupting the supply of electricity, said means making said modules virtually tamper-proof and inaccessible to consumers, being accessible only to authorized technical personnel, for the making of new connections, for the execution of maintenance or emergency services, and for the suspension of the supply of electricity due to consumer default.

Thus, in general terms, the present system is characterized by the grouping of several consumer units into a single supply / measurement / control module installed at ground level, the supply of electricity previously measured to consumers, the elimination of low voltage, and by reading and monitoring the individual consumption of each consumer unit.

In more detail, a first feature of the system innovated by the present patent is that the electricity meters of a convenient number of consumer units (houses, buildings or establishments) situated next to each other are assembled into a single supply / measurement / control module, this module installed outside the territorial boundaries of said units, more specifically, the limits of the public roads on which they are located, and at ground level, that is, on the sidewalk, said module being inaccessible to consumers, however, capable of allowing full visualization of the values recorded by the meters, so that the consumer of each unit has access to the reading and monitoring of their own consumption of electricity.

Another feature of the system now innovated is the fact that each of the supply / measurement / control modules provided for it is formed by a measuring board mounted between two specially designed posts made of concrete and intended for wiring installation. from the power grid; In one of these poles, the transformer is supplied that feeds said frame directly from the medium voltage network, and the interconnection between the transformer and the frame is made inside the pole itself, through a galvanized iron tube; Likewise, the load branches that leave the frame (towards the various consumer units) pass through the other pole, also through galvanized iron pipes.

In turn, the measuring board flanked by said posts is fully shielded, being made of steel and reinforced concrete, including its doors (which may be one or two - versions illustrated in this application - or more), said table It is installed on a concrete base of a predetermined height to prevent water ingress, especially in places subject to flooding.

The doors of the said frame are provided with locks which only

can be opened with special security keys that cannot be copied; This framework is therefore capable of being operated solely by authorized technical persons holding the said security keys, whether for making new connections, performing maintenance or emergency services or for suspension of electricity supply due to consumer default.

Additionally, the opening of said locks must necessarily be done simultaneously, otherwise there is a disconnection (or "trip") of a general electrical protection switch; as a result, any attempt to break into one of the chassis locks will invariably cause the said master switch to automatically shut down as a result of the simultaneous failure to open both of its locks, leaving all electrical circuits exiting the chassis towards consumers unconnected, only the public lighting circuit powered by the switchboard is energized. In this way, any attempt by the unscrupulous people to breach the board will be immediately noticed by all the consumers in that group, since all of them will have automatically cut off their power supply, all of them being directly harmed by that act. of vandalism. As a result, consumers themselves will report and oppose that act, and the attempt to fraudulently capture energy will not succeed.

On the other hand, the glasses in the frame that integrates each of the supply / measurement / control modules of the system are colorless, to allow a clear reading of the energy consumption of each consuming unit, and endowed with high resistance. shockproof and bulletproof. The board also has its own ventilation system, configured by two hoods located on its inner bottom.

An additional feature of the system in question is that the power supply does not have a low voltage grid since, as already mentioned, the switchgear is directly powered by a transformer from the medium voltage grid; In this way, the load branches leaving the said frame, after passing inside the pole, as previously mentioned, go straight to the eaves of the consuming units, through antitheft cables protected by flexible and thermally insulated flameproof conduits.

Thus, it is extremely difficult to make "cats" or "gambiarras" from these conduits that involve the load extensions of the various consumers; however, in the event of any consumer being able to make a fraudulent connection, for example, at a neighbor's charge extension, as such charge extensions are already measured from the frame, such a fraudulent connection will not harm the utility (who will receive it for consumption). already measured from that extension, before leaving the frame), but the consumer himself who had his cargo extension tampered with, since the electricity bill of this consumer will suffer a considerable increase due to the higher consumption resulting from the connection carried out by your fraudster neighbor.

Thus, being directly harmed by this situation, the injured consumer himself will denounce that clandestine connection made by his neighbor, which, consequently, will not succeed in his attempt to fraudulently capture energy.

Each load branch, corresponding to each of the consumer units, is protected by specific circuit breakers, according to their load and phase type (single phase, two phase or three phase). When necessary, the power is cut and the power is reconnected from each consumer unit through these circuit breakers.

The now innovative system also includes several sensors within each supply / measurement / control module (door opening, temperature, vibration and smoke sensors) which, when activated, also switch off (or " disarm ") the aforementioned general switch for electrical protection, leaving the electrical circuits of all consumers switched off, and only the public lighting circuit powered by the switchboard remains energized.

Such sensors are intended to make it even more difficult to attempt to breach the supply / measurement / control module as they provide immediate detection of possible fraud; in fact, at the moment when a first violating action occurs (for example, applying too much force to the frame or its doors, provoking a fire principle, attempting to break glass, etc.), the corresponding Sensors will disarm the master switch, and this will turn off the lights on all consumer units controlled by that frame being tampered with.

Thus, here too, because all units in the area controlled by the module being breached are out of light, consumers will be directly harmed, and will themselves report and / or stop that fraudulent energy capture attempt. The system now innovated also provides for the communication of

several supply / measurement / control modules throughout the city (each controlling a number of consumer units) with one or more monitoring centers (whether or not associated with a GPRS technology system), such that at all times when the switch protection switchboard of a supply / measurement / control module is switched off (for various reasons or various attempts at tampering), the corresponding monitoring center shall be immediately and automatically informed. Then, quickly move a field team to where that module is, to check what happened, sanitize the problem and immediately reconnect the power to consumers who were out of light. Optionally, these centers may call a reinforcement or escort team to provide greater security to the maintenance team when it arrives at the location where the newly violated module is located, thus preventing that team from becoming involved. be robbed by the fraudsters if they are still nearby even after the failed attempt to steal power.

As it turns out, the system now innovated and the equipment employed in that system has the primary purpose of combating theft of energy, both in the measurement itself - since it is absolutely forbidden for anyone to access the energy meters. thus making it impossible for tampering to occur in the measuring instruments themselves - as well as in the low-voltage network - once this network has been eliminated and the already measured load of supply / measurement / control, it becomes practically unfeasible to perform deviations ("cats" or "gambiarras"), and these are denounced by the community itself served by that framework.

With all the innovative features of the system in question and the equipment employed therein, it is possible to totally prevent the occurrence of power distribution fraud, since any attempted theft by a fraudster of a particular group Consumers will be immediately noticed by other consumers, who, being directly harmed by such fraud, will report and oppose this practice and, as a result, will increasingly contribute to discouraging and inhibiting further future attempts at fraud.

As a result, the population will benefit from better conditions and better quality electricity supply, as clandestine connections will cease to exist, and consequently, will no longer cause interruptions in the system, nor cause short circuits and fires.

On the other hand, in addition to this new system providing a visualization of the recorder of the various meters for reading by consumers, it will contribute to facilitate and streamline the services of connection, shutdown and reconnection of electricity by utilities.

The object of the present invention patent is an "ELECTRIC POWER SUPPLY, MEASUREMENT AND CONTROL SYSTEM, AND THEIR EQUIPMENT USED IN THIS SYSTEM", as shown in the block diagram of Figure 1, the system hereby innovated provides for a multiplicity of power supply / meter / controller modules (1), powered directly by a respective transformer (2) from the city's high-voltage grid (3), thereby eliminating the low-voltage grid, each module (1) being responsible for the supply of electricity previously measured to a certain number of consumer units (4), grouped by their proximity.

Said modules (1) are installed at ground level, outside the territorial limits of said units (4), and are provided with visualization means (IA) that allow the reading and monitoring of individual consumption of each consumer unit (4). , further being provided with closing means (IB) and sensing means (1C), conveniently connected to an automation system capable of interrupting the transmission of electric energy, said means (IB) and (IC) making said modules ( 1) practically inviolable and inaccessible to consumers, being accessible only to authorized technical personnel to make new calls, to perform maintenance or emergency services, and to suspend the supply of electricity due to consumer default.

This system also provides for the communication of the various supply / measurement / control modules (1) spread throughout the city - each controlling a certain number of consumer units (4) - with one or more monitoring centers (5), associated or not. GPRS technology system in such a way that, at all times when the switchgear protection switch of each of the said supply / measurement / control modules (1) is turned off (for various reasons or for the most various breach attempts), the monitoring center (5) corresponding to it will be immediately and automatically informed, which will then quickly move a field team to the location of that module (1) for verification of the occurrence, sanitation and immediate reconnection of electricity to consumers

Optionally, the system now innovated also foresees the communication of the several monitoring centers (5) with one or more reinforcement / escort centers (6), to provide more security to the field team, when it arrives at the place where finds the module (1) recently violated, thus preventing that team from being eventually robbed by the fraudsters, in the event that they are still nearby, even after the failed attempt of power theft.

The "EQUIPMENT" employed in said "SYSTEM" consists of said supply / measurement / control modules (1), each formed by a measuring frame (7) mounted on a concrete base (8) of a predetermined height. , to prevent water from entering, especially in places subject to flooding, and flanked by two posts, the inlet (9) and the outlet (10), made of concrete, and intended for the installation of galvanized iron conduits, namely , (9a / 9b / 9c) at the input pole (9), and (10a / 10b) at the output pole (10), these conduits into which the mains wiring will pass.

As best illustrated in Figures 3, 3A and 3B, said posts (9) and (10) are preferably square-shaped, internally hollow (hollow), and provided in their face facing the frame (7) with respective openings for passage. of said electrical wiring; in one of said poles, more specifically in the input pole (9), the aforesaid transformer (2) is conveniently fixed, which feeds only said frame (7) from the medium voltage network (1), whereby the interconnection wiring between said transformer (2) and the frame (7) goes through the pole itself (9), and remains embedded in the already mentioned conduits (9a / 9b / 9c). Likewise, the load branches leaving the frame (7) towards the various consumer units (4) first pass into the other post, the outlet (10), also embedded in the aforementioned conduits (10a / 10b), and reach the upper part of said post (10), from where they are led to the units (4) by flexible anti-theft and flameproof conduits made of galvanized steel, coated with PVC to provide thermal insulation, and provided UV protection.

In turn, the measuring table (7) disposed between said posts (9) and (10) is fully shielded, and may be provided with one or more doors (7a) and have been illustrated in the accompanying drawings. In the present application, two versions, one in which the frame (7) has two doors - see Figures 4 to 4H, and the other in which the frame (7) has a single door - see Figures 5 to 5H.

All faces of said frame (7) (rear, top, bottom and side), as well as its door (s) (7a), are formed by a layer of reinforced concrete coated with a galvanized steel sheet; and both side faces of the board are further provided with respective openings (7b), coincident with the openings of the posts (9) and (10), for passage of the electrical wiring, as already explained above.

Within the said frame (7), the meters are mounted

consumer units (4) controlled by the same module (1), as well as the electrical-electronic components necessary for the adequate supply, measurement and control of the electric power to said units (circuits, circuit breaker, partial circuit breakers, etc.). ). By way of illustration, such components have been shown schematically and in weakened lines in Figure 4F.

Thus, each load branch of a respective consumer unit (4) is protected by a respective partial circuit breaker, which is also used to cut and restart the power when necessary. The general circuit breaker and the partial circuit breakers are sized to meet the load demanded by the consumer units, being specific to the phase type (single phase, two phase or three phase). The panel (7) has its own ventilation system, formed by two hoods (11) and (12), conveniently arranged in respective housings (Ila) and (12a) provided in the lower inner part thereof; one of them (11) serves to remove hot (internal) air from the board, and the other (12) serves to inject ambient (external) air into it, thereby creating forced ventilation.

Furthermore, each supply / measurement / control module (1) is provided with display means (IA), configured by a plurality of windows (7c) provided in the door (s) (7a) of the frame (7), matching the consumption registers of the various energy meters mounted inside the table (7), corresponding to the various consumer units (4) controlled by the same module (1); Such windows 7c are sealed by colorless glass to allow a clear reading of the energy consumption of each consuming unit, which are high strength, shockproof and bulletproof.

Each supply / measurement / control module (1) is also provided with locking means (1B), configured by electric locks (13) that can only be opened with special safety switches; Additionally, the opening of said locks (13) must necessarily be done simultaneously.

Thus, in the event of failure of the opening procedure of the locks (13), they emit an electrical signal to an automation system, which in turn may temporarily render the operation of the keys invalid, or simply sound an alarm, allowing time for a proper new key opening to take place.

In this way, table (7) may only be operated by authorized technical persons holding the security keys, either for making new connections, for performing maintenance or emergency services, or for suspending the system. supply of electricity due to consumer default.

Each supply / measurement / control module (1) is further provided with sensing means (1C), configured by a series of sensors (door opening sensor, temperature sensor, vibration sensor and smoke sensor) which act in conjunction with the aforementioned automation system to respectively identify the following events: non-simultaneous opening or breaking of the door (s) (7a); sudden temperature rises in the vicinity of the module (1), intense mechanical shocks to the frame (7), posts (9) and (10) and the windows of the door (s) (7a), and smoke inside the table (7).

Accordingly, in the event of an improper opening or opening of the door (s) (7a), the door opening sensor signals the automation system to switch off (or "trip") the main switch. protection (general circuit breaker) of table (7), whereby all consumer units (4) controlled by that module (1) will have their electricity supply suspended, remaining only the public lighting circuit, powered by painting.

If the internal temperature of the board (7) exceeds a predetermined value (approximately 50 degrees Celsius), the temperature sensor activates the forced ventilation system provided by the hoods (11) and (12); If the ventilation is not sufficient to cool the frame, thus reaching a temperature higher than another predetermined value (approximately 100 degrees Celsius), the temperature sensor will signal that the automation system will also shut down (or "trip"). ") of the electrical protection general switch (breaker) of the switchgear (7). In the event of severe mechanical shock and breakage of glass, the vibration sensor also signals the automation system to switch off (or "trip") the electrical protection switch (general circuit breaker) of the switchgear (7). ).

And in case of fire, the smoke sensor acts the same way,

that is, it gives a signal to the automation system to shut down (or "trip") the electrical protection general switch (breaker) of the switchgear (7).

As already shown throughout this report, the system and equipment now innovated contribute to virtually eliminating fraud in the distribution of electricity; with them, clandestine connections will cease to exist, and as a result they will no longer be the cause of system disruptions or the cause of short circuits and fires; In addition, the electricity supply, metering and control services will be performed by the utilities under better conditions and with better quality, as well as the electric power cutting and reconnection services will be performed by them faster.
