Hii, pls provide the circuit diagram if possible, otherwise provide the source from where you got these. I assume the second symbol is related to Generator.

An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit.

The first symbol is a feedthrough filter symbol. It is still used in UHF/VHF RF circuits. Used widely in 1960s Audio application product.

The Second one is a gas discharge charge arraster symbol with 250VAC trigger voltage.

An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit.

The graphic symbols used for electrical components in circuit diagrams are covered by national and international standards, in particular:

IEC 60617 (also known as British Standard BS 3939).
There is also IEC 61131-3 - for ladder-logic symbols.
JIC JIC (Joint Industrial Council) symbols as approved and adopted by the NMTBA (National Machine Tool Builders Association). They have been extracted from the Appendix of the NMTBA Specification EGPl-1967
ANSI Y32.2-1975 (also known as IEEE Std 315-1975 or CSA Z99-1975)
IEEE Std 91/91a: graphic symbols for logic functions (used in digital electronics). It is referenced in ANSI Y32.2/IEEE Std 315.
Australian Standard AS 1102. (Based on a slightly modified version of IEC 60617, Withdrawn without replacement with a recommendation to use IEC 60617)
The number of standards leads to confusion and errors.[1] Symbols usage is sometimes unique to engineering disciplines and national or local variations to international standards exist. For example, lighting and power symbols used as part of architectural drawings may be different from symbols for devices used in electronics.
