Abstract
The utility model relates to an electric automatic control security device, comprising a cabinet and a display control device mounted on an instrument door at the upper portion of the cabinet; whereina latching electromagnet is equipped at the right of the front lower portion in the cabinet, a grounding switch interlock mechanism is disposed beside the latching electromagnet, a coil is provided in the display control device, and the latching electromagnet is connected with the coil. The electric automatic control security device has simple structure and safe application.
Description
Technical field
The utility model relates to a kind of electric autocontrol safety device.
Background technology
In field of power, present electric autocontrol device is when upper level transformer station send electricity, and following of its earthed switch is charged, and system is easy to mistake earthed switch is closed a floodgate, and causes the generation of short circuit accident, so very dangerous.
The utility model content
Technology of the present utility model is dealt with problems and is: overcome the deficiencies in the prior art, a kind of electric autocontrol safety device simple in structure, safe in utilization is provided.
Technical solution of the present utility model is: a kind of electric autocontrol safety device, comprise cabinet and the display control device that is loaded on the instrument door of cabinet top, latching electromagnet is equipped with on the right side of preceding bottom in the described cabinet, the other earthed switch interlocking device of being equipped with of described latching electromagnet, in described display control device inside coil is housed, described latching electromagnet is connected with described coil.
The utility model compared with prior art has following advantage:
(1) the utility model is installed latching electromagnet by the right side of preceding bottom in cabinet, in the other earthed switch interlocking device of installing of latching electromagnet, (coil is housed in the inner forced blocking function that increases of display control device, this coil is connected with latching electromagnet), latching electromagnet restriction earthed switch interlocking device.Prevented effectively when upper level transformer station send electricity, caused the generation of short circuit accident after the charged and mistake of following of the earthed switch of this device will earthed switch be closed a floodgate.
(2) latching electromagnet of the present utility model links to each other by transducer with earthed switch interlocking device.When following of earthed switch is charged,, realized mandatory blocking function because the transducer effect flows to latching electromagnet with power supply signal, thereby limited the operation of earthed switch.
(3) the utility model is simple in structure, and cost is low, and is easy to install, and latch performance is reliable.
(4) indication of reporting to the police, alert quiescing earthed switch can appear in the utility model on display control device.
Description of drawings
Fig. 1 is the electric autocontrol safety device front view of the utility model embodiment;
Fig. 2 is the enlarged drawing at A position among Fig. 1.
Figure number explanation: 1-display control device, 2-earthed switch interlocking device, 4-latching electromagnet.
Embodiment
Below with reference to accompanying drawing embodiment of the present utility model is described.
As shown in Figure 1, the electric autocontrol safety device comprises cabinet and the display control device 1 that is loaded on the instrument door of cabinet top, latching electromagnet 4 is equipped with on the right side of preceding bottom in the described cabinet, the described latching electromagnet 4 other earthed switch interlocking devices 2 of being equipped with, described earthed switch interlocking device 2 and described latching electromagnet 4 link to each other by transducer.In described display control device 1 inside coil is housed, described latching electromagnet 4 is connected with described coil.
The content that is not described in detail in the utility model specification belongs to this area professional and technical personnel's known technology.
The utility model is not limited to the protection content that claim and specific embodiment are addressed, so long as any invention of creating out according to design of the present invention all should belong within the protection range of the present utility model.
