Geological disaster, it is ensured that the site terminal box of the reliability of site protective relaying device installation；The utility model solves so
The problem of.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is that providing one kind one kind is used for embedded installation on the spot
Change the terminal box of protective relaying device, protective relaying device of the present utility model is embedded in terminal box, improves installation strength,
Installed even in extreme weather conditions and in the case of geological disaster occurs still reliable；The terminal box of the utility model structure subtracts
Lack engineering site related work amount, saved transformer substation construction cost, shorten the transformer substation construction cycle.
In order to realize above-mentioned target, the utility model adopts the following technical scheme that：
A kind of terminal box for being used for embedded installation site protective relaying device, including：Terminal tank shell, is fixed on terminal

A kind of foregoing terminal box for being used for embedded installation site protective relaying device, protective relaying device composition have：
The device bonnet being fixed on cross-brace beam, is fixed on after device the apparatus housing covered, the relay in apparatus housing
Device, the air plug interface being connected between relay and cable.
A kind of foregoing terminal box for being used for embedded installation site protective relaying device, cable include：Air plug cable and
Optical cable.
A kind of foregoing terminal box for being used for embedded installation site protective relaying device, longitudinal support beam is terminal box shell
The bending edges of body.
A kind of foregoing terminal box for being used for embedded installation site protective relaying device, cross-brace beam pass through horizontal branch
Support beam bolt nut is fixed on longitudinal support beam.
A kind of foregoing terminal box for being used for embedded installation site protective relaying device, in addition to：Seal the close of cable
Sealing.
A kind of foregoing terminal box for being used for embedded installation site protective relaying device, seal is cable gland head.
It is of the present utility model to be beneficial in that：The utility model provides a kind of for embedded installation site relay protection
Protective relaying device is fixed on terminal box shell by the terminal box of device, the utility model by longitudinal support beam and cross-brace beam
In vivo, installation strength is improved, and avoids direct contact with the external world, so even in extreme weather conditions and geological disaster occurs
In the case of install it is still reliable；Cable directly from terminal tank shell inlet wire, reduces the length of air plug cable, cost-effective, simultaneously
Reduce related construction work amount；The terminal box of the utility model structure can realize plug and play, greatly reduce engineering site phase
Workload is closed, transformer substation construction cost has been saved, has shortened the transformer substation construction cycle.
