Definitions

  • the invention is comprised in the technical field of electrical installations, and more specifically in installations relating to electric switchboards.
  • European patent application EP-2259284-A2 discloses a measurement module or kit for being connected in a three-pole fuse block base.
  • This one-piece module includes three strips connected to each of the contacts of the fuse block base, at least one current transformer.
  • This measurement module provides data about the current consumed by a device or apparatus connected to it.
  • the information obtained from this measurement module or kit comprises current values, which is certainly limited because it does not allow having voltage values with a single measurement module, having to arrange additional means to determine voltage, with the time and resources this entails.
  • the information obtained by this measurement module must be sent in any case to a measurement receiving device, which can be analog, digital, or simply a receiving device that collects the information and forwards it to another device that is further away. It so happens, for example, that this measurement receiving device sends the information to a central control room.
  • a measurement receiving device which can be analog, digital, or simply a receiving device that collects the information and forwards it to another device that is further away. It so happens, for example, that this measurement receiving device sends the information to a central control room.
  • the connection between the measurement module or kit and said measurement receiving device is by means of cables. These cables carry the measured current values in the form of an analog signal. One cable is therefore necessary for each parameter to be transported, and although in some cases some parameters can be grouped together, it involves a significant number of cables in any case to be taken from the terminals of the fuse block base to the measurement receiving device.
  • the layout can become a problem due to the large number of cables needed to be arranged, with the cost this entails, in addition to repair difficulties in the event of problems in one of the cables or connections and to the large space necessary for the layout of all the cables.
  • the invention relates to a measurement module for a fuse block base according to claim 1.
  • Preferred embodiments of the measurement module are defined in the dependent claims.
  • the present invention solves the problems mentioned in the preceding section, and is much more versatile, useful and optimal than the measurement modules existing today, needing much less space for cables.
  • the module comprises at least one analog-to-digital converter with at least one digital connection port comprising at least one digital output.
  • a single cable to a receiving device can therefore come out of the corresponding fuse block base to which this measurement module is connected.
  • the measurement module comprises at least one voltage connection.
  • the means necessary for taking the measurement of the current and voltage are therefore provided in a single measurement module, which facilitates said taking of measurements. To that end, it is provided with at least one conductive element for the voltage connection in addition to those of the current connections.
  • the digital connection port of the analog-to-digital converter comprises at least two digital inputs.
  • Placing the voltage connection next to the output terminals of the fuse block base has the following advantages: it facilitates mounting the measurement module because the connections are integrated in the actual module, whereby preventing having to make additional connections in other areas of the low-voltage switchboard to obtain said voltage measurements. Additionally, the information that can be obtained by simultaneously having voltage values upstream of the fuse, for example, in the main busbar, and downstream of the fuse, can be used in a useful manner, for example, to measure and quantify the energy lost in the fuses, or to monitor the state of the fuse, for example, to detect the moment in which the fuse blows.
  • a first aspect of the invention relates to a measurement module for being connected to a fuse block base, said fuse block base having at least three output contacts.
  • the measurement module is connectable to three output contacts of a three-pole fuse block base by means of at least three conductive elements which are connectable to the three output contacts of the fuse block base and on which at least one intensity or current transformer is mounted, preferably one for each conductive element, to provide preferably at least two analog measurement signals, one of them being a voltage measurement signal and another being a current measurement signal.
  • Each conductive element can consist of a conductive strip or of a cable, being easily substitutable with respect to one another, such that said conductive elements allow connecting the measurement module with different output contact typologies that fuse block bases can have.
  • the measurement module further comprises:
  • said at least one analog-to-digital converter collects the measurement signals of the measuring device and converts them into a digital signal.
  • This digital signal can be transmitted through a single cable.
  • Said cable is connectable to a receiving device, which can be installed in the actual electric switchboard, and this receiving device can send the data to a central control system.
  • the module comprises a casing containing at least said at least one intensity transformer, and on which said at least three conductive elements are mounted is contemplated, thereby allowing connecting the measurement module to the three output contacts located at one end, usually the lower end, of a three-pole fuse block base.
  • the converter can incorporate at least one digital input in addition to said at least one digital output, such that several analog-to-digital converters of the different fuse block bases are interconnectable.
  • Said digital input is envisaged for being used to transmit data in the form of a data bus, etc.
  • each analog-to-digital converter comprises a digital input and a digital output, forming a loop, allowing the information to go from one converter to another with information from all the interconnected bases such that a single cable to the receiving device can come out of the last converter.
  • the converter is an integral part of the measurement module. Once the measurement module is connected to the fuse block base, said fuse block base is installed in the switchboard and it is only necessary to connect a single output cable of the converter.
  • the measurement module comprises at least one electrical connection point, such as a terminal block, to which said at least two analog inputs of the analog-to-digital converter are connected.
  • at least one electrical connection point such as a terminal block
  • the device comprises the following additional advantages:
  • intensity transformers In addition to the current measurement through intensity transformers, it also includes a voltage measurement, so it therefore allows calculating power consumption as well as other necessary parameters for better managing the grid.
  • the strips are fixed such that certain movement thereof is allowed in order to be adapted to the range of measurements that the connections of the base may have, e.g., due to deformations caused by the prior mounting. This is done by fixing the strips to a flexible area of the casing.
  • the kit allows being able to continue using the protective terminal cover of the standard base, also referred to as connection cover.
  • the same cover is fixed to the casing of the measurement kit, such that the output terminals continue to be protected.
  • the kit is usable in bases in both the upper and lower output positions.
  • the converter can be placed in any part of the measurement module.
  • This converter incorporates an electrical connection point connected by means of cables to the electrical output connection point of the measurement module.
  • a second aspect of the invention also relates to a fuse block base with a measurement module as it has been defined above.
  • a three-pole fuse block base (1) of the state of the art comprises, in a known manner, three pairs of contacts (2), each pair of contacts (2) being electrically connected to a conductive strip, which has not been depicted, of the low-voltage switchboard of the corresponding electrical installation. There is one pair of contacts (2) for each electrical phase. A fuse (3) is coupled in each pair of contacts (2). The non-depicted conductive strip is connected to the fuse block base in its rear portion, i.e., in an area opposite the fuses (3).
  • fuses (3) are generally mounted in a cover hinged to a casing (4) of the fuse block base (1) where the pairs of contacts (2) are located, such that when the cover is closed on the fuse block base (1), the fuses (3) are coupled in their respective pairs of contacts (2) closing the electrical circuit. When the cover is opened, the fuses (3) are disconnected from the contacts (2).
  • the fuse block base (1) furthermore has output contacts (5, 5') to which the corresponding electric cables are fixed. These cables reach the equipment to be powered.

It is also contemplated that each flange has a sharpened element contacting the conductive element (20, 20'), perforating the plastic covering in the event that it is a cable (20').
  • the voltage connection is established by means of a conductor in electrical contact with the output contacts (5, 5'), directly on them or on the conductive elements (20, 20') which are connected to said output contacts (5, 5'), or on any intermediate element that is used to assure the electrical contact between the output contacts (5, 5'), and the conductive elements (20, 20').
