The

article

focuses on

the

heating

problem

of

high

voltage

switchgear.

In

the

existing

simulation

analysis

of

temperature

field

of

10

kV

high-voltage

switchgear,

it

is

difficult

to

calculate

its

internal

temperature

accurately

because

of

the

complex

internal

structure,

material

properties

and

heat

transfer

process

of

10

kV

high-voltage

switchgear.

In

order

to

solve

the

above

problems,

a

temperature

field

simulation

method

of

10

kV

high

voltage

switchgear

based

on

transfer

module

in

COMSOL

is

proposed.

By

using

this

simulation

method,

the

steady

temperature

value

of

10

kV

high

voltage

switchgear

can

be

solved

effectively,

the

steady

temperature

field

can

be

simulated

accurately,

and

the

error

of

the

results

is

small,

which

conforms

to

the

actual

temper­ature

distribution

law.

Finally,

the

validity

and

accuracy

of

the

proposed

method

are

verified

by

the
