Definitions

  • the invention relates to a protective device for a load current-carrying device for preventing or reducing an arc during a separation process from the load current-carrying plug contacts using a switch that reduces the load current so far that a harmless load current remains with a device attachable protective cover for the load current plug contacts, the pulling the load current plug contacts difficult as long as it is attached to the device, wherein the protective cover has a means which is so in operative connection with the switch that the load current is reduced by the switch when the protective cover is removed from the device.
  • a protective device in which an arc protection is realized in that a clocked semiconductor device is used. This is connected in series with an auxiliary contact.
  • the auxiliary contact is designed as a trailing contact, so that it is disconnected after the load current contact. As a result, the load current has been reduced so far, when the load current contacts are separated, that no arc is formed.
  • Inverters with an integrated DC load disconnector are known. However, it may be forgotten to operate this before the load plugs are removed. This can cause an arc, which can lead to personal injury.
  • a device for the grid connection of a solar generator wherein a module distributor and a network coupling device are provided.
  • the module distributor inputs for solar modules and an output for a network coupling device, wherein the network coupling device is connected to one or more inverters, and moreover has an output for one phase of the AC network.
  • the inverter has a cover which mechanically disconnects the inverter when it is lifted.
  • Both DE 198 82 471 T5 and US Pat. No. 5,542,425 A disclose a protective device of the aforementioned type.
  • the opening is detected by a detection switch when opening the protective cover, wherein when the detection switch responds when charging a battery or the power supply by the battery, an internal switching circuit of the power control unit is opened.
  • the invention has for its object to provide a protective device of the generic type, which protects against arcs in a simple manner.
  • the switch can be configured as a semiconductor switch, clocked semiconductor switch, as a relay or as a so-called one-time switch.
  • a one-time switch is understood to be a switch which can not be closed after a single actuation; he acts as a kind of security.
  • the protective cover according to the invention prevents on the one hand, that the load current contacts are pulled, as long as they are mounted on the device.
  • the protective cover is removable. By removing the protective cover acts the inventive means in which the clocked semiconductor device is used. This reduces the load current so far that when removing the load current contacts no or at least only a harmless arc for people can arise.
  • the protective cover according to the invention allows additional load disconnectors in the device to be dispensed with, since disconnection at high load current is not possible without the invention. In this way, the relevant standards and regulations are complied with.
  • the control means may be a mechanical or electromechanical means.
  • an actuating pin or the like may be provided on the protective cover which operates a switch provided on the device when the protective cover is mounted.
  • the switch contacts of the switch are parallel to the clocked semiconductor switch. This in turn lies in the load circuit, in particular in the DC circuit.
  • the switch is closed so that the load current flows through the switch.
  • the contact is opened so that the load current through the clocked Semiconductor switch flows. Since this current is now less or is clocked, an arc protection is given.
  • an electrical solution is used in which the protective cover has electrical contacts for electrical connection with additional contacts on the device, so that when removing the protective cover, the contacts of the protective cover separated from the additional contacts and the load current is reduced.
  • the protective cover comprises a short-circuiting bridge as a means which short-circuits the additional contacts when the protective cover is mounted over the contacts of the protective cover.
  • the short circuit bridge integrated in the protective cover creates a very simple control of the load current.
  • the shorting bridge will engage and the load current may be high. If the short-circuit bridge or the cover is removed, a lesser current sets in through the clocked semiconductor component, which interrupts the current continuously at regular or even irregular intervals.
  • the short-circuiting bridge is connected in parallel with the semiconductor component and the semiconductor component with the short-circuiting bridge lies in the load circuit.
  • a closed switch would bypass the semiconductor device.
  • the current goes the path of least resistance.
  • the load current flows through the low-resistance bridge. If this is missing because the cover has been removed, the current must flow over the clocked semiconductor switch. As a result, however, the load current is reduced to a safe level.
  • the semiconductor device can be clocked continuously, which is easy to implement. Since the load current flows through the low - impedance current bridge when the protective cover is mounted, the Semiconductor device no switching losses, resulting in a high efficiency.
  • the device comprises an inverter module and the semiconductor device is housed in a clock module which is electrically connected to the inverter module.
  • FIG. 1 shows a preferred embodiment of the protective device according to the invention for a photovoltaic inverter 1.
  • the inverter 1 is provided with plug contacts 2, which lead a load current for an input side DC voltage circuit.
  • plug contacts 2 PV plug 4 (photovoltaic plug) can be connected, which are connected to photovoltaic modules 3 (solar generators), as Fig. 2 illustrates.
  • the protective device is preferably located on a DC circuit, in particular on an input-side circuit (DC circuit).
  • a protective cover 5 can be mounted in front of the PV plugs or the plug contacts 2, as FIGS. 1 and 3 illustrate.
  • the protective cover 5 can be positively and / or non-positively attached to a housing of the inverter 1. When mounted, the cover prevents the PV plugs 4 from being pulled out and breaking the load circuit at high current. An interruption of the load circuit during a high load current would cause an arc.
  • a module 6 with a clocked semiconductor switch 7 is connected in series to an inverter circuit or an inverter module 8, as FIG. 2 shows.
  • a current bridge or short-circuiting bridge 9 which is integrated in the protective cover 5.
  • the shorting bridge 9 is automatically connected to existing on the protective cover 5 contacts 10 and additional contacts 11 on the housing of the inverter 1 when the protective cover 5 is mounted. The load current can thus flow with little loss via the shorting bridge 9 during operation.
  • the short-circuiting bridge 9 is connected practically parallel to the semiconductor switch 7.
  • a device attachable protective cover 5 for the load current plug contacts 4 is present, which prevents removal of the load current plug contacts 4, as long as it is attached to the device, the protective cover 5 has an electrical and / or mechanical means (shorting bridge), which is in operative connection with the semiconductor device or the semiconductor switch 7, that the load current is reduced by the semiconductor switch 7, when the protective cover 5 is removed from the device.
  • the integrated in the protective cover 5 means or control means controls in the broadest sense in a simple manner the load current.
  • FIG. 4 shows a further circuit diagram which shows the arrangement of the short-circuiting bridge 9 and of the semiconductor switch 7.
  • the short-circuiting bridge 9 preferably short-circuits additional contacts 11 or lies parallel to the semiconductor switch 7.
  • the additional contacts 11 are attached to the device.
  • the semiconductor switch 7 is driven by a clock controller 12, so that the semiconductor device is continuously clocked.
  • the timing is set so that no dangerous arc is formed at the additional contacts 11 when the protective cover 5 is removed.
  • FIGS. 5 and 6 show the principle of the current reduction according to the invention.
  • the semiconductor switch 7 is shown in simplified form as a switch. Parallel to this is the shorting bridge 9, which is also shown in simplified form as a switch.
  • the switch 9 could be integrated in the device and formed on the protective cover 5 mechanically actuated. For operation, an actuating pin or the like which would be attached to the protective cover 5, could serve.
  • the protective cover 5 has a handle 13, which is preferably formed as a wall. As can be seen in FIG. 3, the protective cover 5 conceals both the auxiliary contacts 11 and the load current or PV contacts.
  • the protective cover 5 is preferably made of plastic, for example a thermoset or thermoplastic. It has, for example, a three-dimensional shape and preferably carries end walls 14, as FIG. 3 shows. A central web 15 stiffens the cover or serving as a handle 13 wall.
  • a separate contact 2a, 2b is used for each independent input of the inverter.
  • four or more contacts 2 are present. Therefore, several additional contact pairs are used, in particular two pairs, as shown in FIG. 3.
  • the protective cover 5 is so inventively arranged on the inverter that in the mounted or mated state, the plug-in connections of the inverter are hidden and can not be operated. By removing the protective cover 5 by the integrated electrical contacts a function is triggered, which ensures that a maximum of a harmless for the removal of the connector plug of the inverter current flows through the plug-in connections. By removing the protective cover 5 continues to access the plug-in connections (Contacts 2) released, so that at the latest by the then following removal of the plug-in connections from the inverter a complete separation of the upstream energy source (eg PV system) takes place.
  • the upstream energy source eg PV system
  • the additional control unit for covering the inverter's connectors effectively prevents arcs that can lead to personal injury.
  • the load current is not completely switched off, but it remains a pulsed, small current.
  • the constant switching on and off of the semiconductor switch not only reduces the current, but also extinguishes an arc due to the clocking.
  • a hinge hinged cover can alternatively be used.
