Description
Technical field
The utility model belongs to controller switching equipment technical field, and in particular to a kind of headlamp inside arcing emergency protection dress
It sets.
Background technique
Switchgear assembly is a kind of electric equipment distributed electric energy and control electric energy, some are that outside line is introduced into master control in cabinet
Switch, subsequently into sub-control switch, each branch, which is set according to its needs, distributes to power load, such as measuring instrumentss, automatic control, electricity
Motivation magnetic switch, various A.C. contactors etc..Switchgear assembly is divided according to voltage class, is divided into high pressure complete switch and is set
Standby, middle pressure switchgear assembly and low-voltage complete switch equipment.
Switchgear assembly is a kind of equipment being widely used in various distribution electric energy and control electric energy place, at these
Many switchgear assemblies need to have the interior indiffusible function of arcing failure in current high quality power requirement in
It can protection.As having internal moment kindling caused by the failures such as over the ground of individual event caused by short circuit or insulation breakdown inside equipment, putting
Phenomena such as electric, this phenomenon have very high temperature inside equipment and open fire occur, while generating biggish pressure once occurring
And high temperature, it needs and especially moment is protected to make interior arcing failure not to external diffusion, there is miscellaneous protection to do in industry at present
Method.However, cable vault or bus-bar room repairing lighting are that numerous producer's processing prevent internal arcing again in switchgear assembly
Weak link, specific disadvantage have the following：
First, there are part high-low pressure complete set of equipments cable vault or bus-bar room repairing lighting lamp to be directly installed on equipment door-plate
On, later without any protection；When occurring interior arcing failure inside equipment, since internal temperature is very high, outside repairing lighting lamp
Shell bracket is plastic material, in moment i.e. by high temperature melting, has biggish high temperature pressure inside equipment at this time, moment makes interior arcing
Failure is to external diffusion.
Second, there is part that cable vault or bus-bar room repairing lighting lamp are directly placed in equipment cable room or bus-bar room inner panel
It is interior, since high-tension switch cabinet high-tension cable room or bus-bar room have high voltage appearance power supply, in equipment normal control or distribution electric energy
When, it is fail to open cable vault or bus-bar room door-plate or sealing plate, once lead to cable vault or bus-bar room repairing lighting lamp light bulb in this way
Damage can not be maked an inspection tour normally, such as need to change repairing lighting lamp light bulb, it is necessary to which thus power failure operation gives downstream in current check
Production brings inconvenience, brings no small maintenance cost to maintenance.
Third, in addition there are also partial cables rooms or bus-bar room repairing lighting lamp in cabinet door, and outside has one layer of iron plate
Cover board is sealed by several screws, when needing replacing light bulb such as cable vault or bus-bar room repairing lighting lamp, needs to tear open the spiral shell of a circle
Silk, efficiency are very low.In addition, risk is very big at this time if occurring arcing failure inside equipment when worker more changes the bulb.
4th, cost of labor and maintenance cost are big.
