Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] In view of the fact that the working position of maintenance is far away from the main control room, and the on-site staff cannot effectively get the corresponding sound prompt information, the following design is designed: figure 1 The shown substation fault trip sound and light alarm device includes a power supply module, a control circuit module, a signal acquisition module, an LED display module, an alarm module and a cooling module. The power module provides working power for all modules.

[0018] The control circuit module is respectively connected with the signal acquisition module, the LED display module, the alarm module and the cooling module. When the tripping signal is trans...

Abstract

The invention discloses a failure tripping sound-light alarm device of a substation. The failure tripping sound-light alarm device comprises a power module, a control circuit module, a signal acquisition module, an LED display module, an alarm module and a heat dissipation module. The failure tripping sound-light alarm device is characterized in that the signal acquisition module is provided with a signal receiving end, a current-limiting resistor and a photoelectric coupler. The failure tripping sound-light alarm device has the advantages that a tripping signal flows through the photoelectric coupler via the current-limiting resistor, so that a triode of the photoelectric coupler is powered on, the electrical potential changes, a master control device acquires signal change, and the words 'failure trapping' are displayed through the LED display module; the alarm module triggers an alarm unit to give an alarm to remind staff of attention, and therefore the staff can reset equipment and stop the alarm temporarily through a man-machine interface device; even if the overhaul working position is far from a master control room, the field staff can effectively obtain the alarm signal; as a result, the failure tripping sound-light alarm device gives out prompt information effectively in time, and the working efficiency of the staff is improved.

Description

technical field [0001] The invention relates to an acousto-optic alarm device for substation fault tripping, which belongs to the technical field of high-voltage power grid operation fault alarm. Background technique [0002] Substation is an important part of power transmission and distribution in the power system, and undertakes the important task of receiving and distributing electric energy. At the same time, there are many devices in the substation, and various failures often occur. When a fault occurs while someone is operating the equipment, if the work cannot be stopped accurately and timely and then diagnosed and restored, it will cause equipment damage or personal injury, and even cause other cascading faults to cause large-scale power outages, seriously affecting the normal operation of the power system. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an audible and visual...
