Description
Technical field
It the utility model is related to switch device cabinet bodies technical field, and in particular to a kind of Novel switch cabinet arrester installation knot
Structure.
Background technology
35kV switch device cabinet bodies are compact, floor space is small, be widely used in power transmission and transformation system electric substation by distribution, industrial and mineral
The occasions such as enterprises and institutions, equipment Electrical Safety are particularly important to whole system normal operation.Because installation site is limited in cabinet, although band
Goddess of lightning's line employs material contracting with heat and epoxy coated insulating meanses, can meet safe distance requirement, but the powered position pair in part
Ground（Metal shell）In small distance, we pass through the design to more times of 35kV metal armored withdrawal-type switching devices KYN61-40.5
Found with experiment：
1. though having certain insulating capacity arrester leader cable insulating barrier is organic material, dielectric level does not reach will
Ask；
2. because of KYN61-40.5 structure constraints, cable outlet cabinet arrester is installed after generally leaning on cabinet, is pacified using former arrester
Base is filled, cable tail touches housing and be likely to get an electric shock from cabinet door distance 280mm or so, operating personnel, potential safety hazard be present.
3. when there is a stronger voltage to pass through from arrester, electric charge can be along arrester silicon rubber skirt surface creepage, due to keeping away
Thunder device and installing plate are closer to the distance, and electric current can flow through from the installing plate of side, so that the on-line computing model quilt on installing plate
Breakdown, causes to damage.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of Novel switch cabinet structure for installing lightning arrester, by changing
Enter mounting seat structure type, effectively increase the distance of arrester cable tail over the ground, on the door, operating personnel are got an electric shock, electrically
The possibility that accident occurs reduces.
The utility model is achieved by the following technical solution：
A kind of Novel switch cabinet structure for installing lightning arrester is provided, including rear is provided with the cabinet of observation window, described cabinet
Arrester is fixed with by base on the bottom plate of observation window and on-line computing model, described bottom are fixed with by installing plate
The lower surface of seat is parallel with bottom plate and angle α at an acute angle, wherein acute angle α opening directions are seen between its upper surface and lower surface
Examine the cabinet of window side；Described arrester is arranged on the one end at the upper surface vertical height bottom of base, described installing plate one
End is fixed on high one end of upper surface vertical height of base, and installing plate is fixed with one end of on-line computing model to observation window side
Inclination and the angle β at an acute angle between the lower surface of base.
There is acute angle α base between upper surface and lower surface by setting, arrester tilted and is installed in cabinet,
And installing plate is set to the tank leaning of observation window side so that the distance of the distance of arrester and door, arrester and installing plate
Increase so that arrester when passing through a stronger voltage, electric current can be imported from top to bottom along arrester the earth, so as to reduce because
Arrester is closer to the distance with installing plate, causes electric current to be transferred on installing plate so as to cause punch through the hair of on-line computing model situation
It is raw.
Further, described acute angle α is 10 ° ~ 25 °.
Base upper surface and the acute angle of lower surface are the inclined installation angle of arrester, and α is arranged on 10 ° ~ 25 °
When, it is ensured that arrester does not contact with miscellaneous part in cabinet, causes electric leakage or conductive condition to occur.
Further, described acute angle β is 30 ° ~ 60 °.
The inclined installation angle β of installing plate is arranged to 30 ° ~ 60 ° on-line computing models that its end is installed for convenience can
Instrument board is shown in observation window, facilitates staff to observe and record data, compared to vertically arranged on-line computing model, is inclined
Tiltedly installation not only increases the distance of installing plate and arrester, prevents that current flowing occurs between the two, and causes work people
The visible angle increase of member, more convenient observation.
The beneficial effects of the utility model：
First, by installing inclined base so that arrester is respectively relative to vertical direction with installing plate and tilted to its both sides
Set, increase distance between the two, can effectively prevent electric current on arrester from introducing installing plate, can prevent from monitoring on-line
Instrument is punctured by electric current, protects on-line computing model.
2nd, the distance of arrester cable tail over the ground, on the door is effectively increased, operating personnel are got an electric shock, electrical hazard occurs
Possibility reduce.
3rd, the installing plate for installing on-line computing model and arrester are all installed on base and are located at base both ends respectively,
So that in maintenance or dismounting, convenient operation, while enhance integraty in cabinet.
