Problems solved by technology

However e.g. Kevlar is too expensive to be used in most frequency converter enclosures
Additionally, known bulletproof structures offer little protection against vibrations from gunfire, which are just as capable of damaging electrical equipment as penetrating gunfire
Known structures also fail to protect against sharp temperature changes between hot during the day and cold at night

Embodiment Construction

[0025] In the method according to the invention, the cover is produced in such a way that it can be equipped with protective material when the cover is installed. The cover is therefore preferably sent to the site without a protective element, ie a protective layer of absorbent material. The cover is thus made to have at least two nested shells, between which there is a cavity for receiving the protective element. Such as figure 1 As shown in , the enclosure has an inner shell 5 for receiving electrical equipment. Such shells are known per se. Electrical equipment can be any equipment that requires protection, but usually one specific type of equipment that requires enhanced protection is a frequency converter. This is because VFDs are commonly used on drilling rigs and for vulnerable operations such as this, where equipment is most likely to be exposed to sudden gunfire.

[0026] As said, the inner casing 5 surrounds the device. In the manufacturing stage, the second out...

Abstract

The present invention relates to an outdoor enclosure for electronic equipment and a method for providing an outdoor enclosure for electronic equipment for providing a robust and inexpensive enclosure for protection against gun fire and high temperature variations, in which method an enclosure having an inner shell (5) and an outer shell (1) en-closing the inner shell (1) at a clearance thereof is formed, whereby a cavity is formed between the shells (1, 5). Electrical equipment is enclosed within the inner shell (5). Natural granular absorption materials (4) are provided as the protective layer into the cavity on site upon installation of the enclosure.

Description

technical field [0001] The present invention relates to shielding structures. In particular, the present invention relates to protective covers for electronic equipment, these covers are designed to protect the equipment from external influences, such as gunfire and heat. More precisely, the invention relates to a method for providing a protective cover according to the preamble of claim 1 and a cover according to the preamble of claim 4 . Background technique [0002] Electronic equipment such as frequency converters are usually safely housed indoors or in enclosures suitable for outdoor use. Since some operations, such as oil drilling, take place in environments considered hostile in political turmoil or prone to sabotage, the need for suitable protective enclosures has arisen. In fact, common sites where frequency converters are used, such as oil drilling areas, are often plagued by various threats. Surprisingly, many inverter boxes suffer from gunfire, which is why a ...
