JB/T10164-1999
The main switch should be selected from suitable materials that meet the use requirements, and after forming the main switch, it should comply with the relevant test requirements, and special attention should be paid to the flame retardant and moisture resistance of the materials and the necessity of protecting certain insulating materials from moisture. All materials used should comply with their respective relevant standards, and the brand, specification, state, etc. of the materials should comply with the requirements of relevant technical documents.
The suitability of the selected materials can be verified by the following tests, which can be carried out on the control switch and (or) the components of the control switch. a) Ageing resistance;
b) Moisture resistance;
c) Heat resistance;
d) Resistance to extreme heat and fire hazards: Www.bzxZ.net
e) Rust resistance.
For heat resistance, extreme heat resistance and fire hazards, the tests should preferably be carried out on the control switch and (or) suitable components removed from the control switch, however, in some cases, for special reasons, it may be permitted to replace the tests on the control switch or a component with tests on the preselected materials.
4.4.1.1.1 Ageing resistance of elastic components Elastic components of the control switch made of rubber, polyvinyl chloride (PVC) or similar materials should have ageing resistance. The test to verify the ageing resistance is specified in 6.1.1.
4.4.1.1.2 Moisture resistance

4.4.1.1.4 Resistance to abnormal heat and fire Insulating material parts may be subject to thermal stress due to electrical effects, and insulation deterioration may impair the safety of the main switch. These parts shall not fail or endanger safety after being subjected to abnormal heat and fire. The test method for verifying the resistance to abnormal heat and fire is specified in 6.1.4.
4.4.1.1.5 Rust resistance

Any screws that transmit contact forces shall engage on metal threads.

The requirements shall be verified by visual inspection and specified tests. 4.4.1.3 Electrical clearance and creepage distance
JB/T10164-1999
For main switches with rated impulse withstand voltage values (U.) specified in specific product standards, the values of electrical clearance and creepage distance are shown in 4.4.1.3.1.
For main switches whose rated impulse withstand voltage value (U) is not specified in the specific product standard, the minimum electrical clearance and creepage distance values are shown in 4.4.13.2.
Note: This standard recommends using the rated impulse withstand voltage to determine the electrical clearance and creepage distance. 4.4.1.3.1 Main switches with rated impulse withstand voltage (Um.) specified 4.4.1.3.1.1 Clearance
a) Insulation coordination of the system
The insulation coordination of the main switch is based on the priority system of transient overvoltages being limited to the specified impulse withstand voltage. The external transient overvoltage must be lower than or limited to lower than the impulse withstand voltage specified by the power system, and the transient overvoltage generated by the main switch in the system must also be lower than the impulse withstand voltage specified by the power system. Therefore, the conditions for the main switch to be used in the power system are: the rated insulation voltage of the main switch should be higher than or equal to the rated voltage of the power system. The rated impulse withstand voltage of the main switch should be higher than or equal to the rated impulse withstand voltage of the power system. The transient overvoltage generated by the main switch should be lower than or equal to the rated impulse withstand voltage of the power system. b) Rated impulse withstand voltage
When designing the main switch, it should generally be considered that the main switch is suitable for multiple power systems and one or more installation categories. Therefore, the rated impulse withstand voltage of the main switch should be determined according to the relatively highest voltage and installation category in the multiple power systems expected to be used. In the insulation coordination system with the normally specified overvoltage limit, the corresponding relationship between the installation category, the relative voltage to ground determined by the rated voltage of the power system and the rated impulse withstand voltage is shown in Table 3. Unless otherwise specified, the rated impulse withstand voltage of the main switch is recommended to be selected according to Table 3. Table 3

c) Determination of the electrical clearance value

(1.2/50μs.2000m Umg)
Installation category II
Under the conditions of installation category II I, the minimum electrical clearance of the main switch is listed in Table 4. The minimum electrical clearance specified in Table 4 is determined considering the altitude of 2000m. Therefore, it is also applicable to the altitude range of less than 2000m.

Minimum electrical clearance
Pollution level 2
Pollution level 3
Note: The electrical clearance value specified in the table is not used for the contact opening distance and the part affected by the arc. If the main switch uses an electrical clearance smaller than that specified in the table, it must be subjected to the impulse withstand voltage test corresponding to the highest installation category as specified in 7.1.3 of GB/T14048.11993. Creepage distance
4.4.1.3.1.2
The minimum creepage distance of the main switch is related to the rated insulation voltage (or actual T operating voltage), pollution level and insulation material group of the main switch.
Insulating materials can be divided into four groups according to their comparative tracking index (CTI): a) Insulating material group I
b) Insulating material group II
c) Insulating material group IIIa
d) Insulating material group IIIb
600≤CTI
400≤CTI<600
175≤CTI<400
100≤CTK175
For the determination of the comparative tracking index (CTI) of insulating materials, see 6.16. The creepage distance of the main switch shall be selected according to the values specified in Table 5. 4.4.1.3.2 Main switch with unspecified rated impulse withstand voltage (Um) The following applies to the main switch used in air and under normal atmospheric conditions specified in this standard. When the atmospheric conditions of the use environment are different from the normal atmospheric conditions, the outer shell or a larger creepage distance may be selected. Compliance with this clause does not imply that the main switch meets the requirements of this standard.
4.4,1.3.2.1 Basic requirements
a) It is recommended to design insulating parts with ribbed surfaces to block the conductive paths formed by conductive deposits. b) The recommended electrical clearances and creepage distances apply to parts where no arc occurs. In areas near arcs or where free gases exist, the atmospheric conditions specified in this standard do not exist, so the values of electrical clearances and creepage distances need to be increased. c) The recommended electrical clearances do not apply to the air gaps between separated contacts on the same pole when in the disconnected position. d) Conductors coated only with varnish and enamel, or protected only by an oxide layer or similar method, cannot be considered to be insulated. e) The recommended electrical clearances and creepage distances must be maintained in the following cases: 8
